v6.42rc [release candidate] is released!

anuser · Sat Feb 17, 2018 1:45 am

What's new in 6.42rc27 (2018-Feb-14 11:53):
*) wireless - added support for "band=5ghz-n/ac" (CLI only);

1. setting this one within CAPSMAN would be nice to have.
2. What will be the difference between "band=5ghz-a/n/ac" and "5ghz-n/ac"? Some kind of old compatible mode on the first one that will be disabled on the second and therefore results in higher performance?

It's like the 2ghz-g/n, where is disabled the 802.11b.

Is it ok to upgrade from 6.42rc3 to 6.42rc28?

I tried to upgrade from v21 to v24 and it caused by x86 routerOS fail to have connection. I have used sometimes to restore the older working version. The one I got at home was rc3.

*) wireless - fixed incompatibility with macOS clients

can mikortik tell us if this is (presumably) implied for capsman as well?

yes mikrotik, please tell us if disabling an old band mode results in an improvement. dont make me create a new email ticket for every question

Alessio Garavano · Sat Feb 17, 2018 6:52 am

Hi guys, it would be great if you allow to select, within each update channel, 5 or 6 previous versions, in order to update the RC versions correctly and correlatively.
Or make a downgrade directly to the previous version that we liked or better worked for us.

Thanks and regards,

Bricked RB3011UiAS-RM by updating from rc20 To rc27.

LCD shows always "starting services"...

Netinstall wont work anymore... LCD shows ether Boot but Router will not apear in netinstall GUI. Troubleshoot this with other mikrotik products they imedatly apear on the GUI at the same win7 machine with same settings and cable/port...

don't update from any RC!!! it will brick the device.

CPU hog issue is still not fixed in rc28
(Ticket#2018010522007579)

pe1chl · Sun Feb 18, 2018 12:25 am

I had a CHR that was originally installed on VMware ESXi some versions ago when only the bare disk image was available.
(using the trick of converting the image to SCSI)
It initially had ether1 connected to a LAN network (which has access to internet via another router), later ether2 was added
directly connected to internet, and configured in RouterOS. It had Dude installed but not enabled at this time.

As it was effectively stuck at 6.42rc20 because of the update bug, I exported the config and the dude database and created a
new VM from the 6.42rc28 OVA file. I connected ether1 to the LAN and added a second network interface to the VM, again
connected to internet as before.

However, whatever I try, RouterOS sees the LAN interface as ether2 and the internet interface as ether1. So what is called
network interface 1 in ESXi is ether2 in RouterOS.
Even when I deleted the second network interface and reset the configuration, seeing that LAN is ether1 and everything is correct,
as soon as I added the extra interface the names were swapped again.

I gave in and edited my exported config to match the swapped ether1 and ether2 and everything now works as before,
but what is going on here? it is confusing and inconvenient.

The same occurs in VirtualBox since rc23 (I saw this after the upgrade from rc20 to rc23).

I configured a fresh CHR in rc27, on first try, swapped the interfaces. On second try, was disabled the NIC #2 and I did a MAC reinitialize in both interfaces. Booted with one interface and I added a new IP to ether1 and then was shutdown. Was enabled NIC #2 and booted, then the problem stopped.
I upgraded to rc28 and no problem with swapped interfaces.

The interfaces that I use in VBox are "Intel PRO/1000 MT Desktop", NIC #1 as bridged and NIC #2 as NAT Network.

indnti · Sun Feb 18, 2018 11:17 pm

Answered many times before! The old version is the one that performs upgrade. We can't fix a released and installed version.

If you bring out a version that *bricks* hardware you must consider that it will not happen. maybe a special intermediate version to repair version rc20-24. It can not be true that one be forced to use rc20 till the end of lifetime of that hardware!

Hello!

Well, RC Versions are not meant to be production ready versions. So expect them to break stuff. And because of that, only use them in a lab or test environment, where you are happy to do netinstall if things break.

PS: I still advocate that MikroTik changes the name of the "release candidate" version to "beta", "development" or "unstable" version. Just to be crystal clear about it's purpose and for the sake of customer happiness.

Could you please send the supout file to support, we would like to take a look at it.

Which ESXi version are you using?

Also, please explain in more detail what exactly did you do: did you upgrade from an earlier rc? Or from current version? From which?

Thanks.

6.42rc28 wrecked my CHR on libvirtd / Qemu KVM setup. Virtio network interfaces (or any interfaces at all) aren't recognized anymore.

Do not install 6.42rc28 on KVM CHR!

Still trying to salvage this thing, will write more later...

Add: Just managed to get 6.41.2 installed. Had to get the stable package file to the guest first somehow, which if you don't have any way of officially interacting with the guest on the host (interfaces are all down) is quite the ordeal:

mount raw image with manually calculated offset

put file in right place in Linux file system underlying RouterOS

run guest, qemu console to it, login, do /system package downgrade

I can only repeat: Don't install rc28 on QEMU/KVM!!

Yes. "Release Candidate" normaly is something that is expected to be near production quality:
https://en.wikipedia.org/wiki/Software_ ... _candidate
And at least CRS317-1G-16S+RM needs the rc to work. And there is no hint CRS317-1G-16S+RM is a beta product.

So please MT increase your SW Development Quality control to protect your customers from bad experience.

pe1chl · Mon Feb 19, 2018 11:29 am

I encountered another problem in my "fresh 6.42rc28 install then import old config" that I forgot to mention above:
I am using the serial port on this CHR (configured to map to the hardware serial port in the VMware ESXi config) to
connect to the serial port of a CCR router at the same site. This is an emergency access in case there is some
error in the CCR config. (the CHR is on a bridge in the CCR so it will not always be useful, but one can always try)

Well, for that config in the previous version there was this:

/port
set 0 baud-rate=115200

On the new version this config is refused with "cannot set speed because port is in use".
(and the import stops there! that is another issue that should be fixed: when such an error is encountered when
importing a config, the import should just go on with the next step. this kind of problem makes it impossible to
do a /system reset-configuration no-defaults=yes run-after-reset=scriptname because almost always there is some
minor hiccup like this and you are left with an unconfigured router)

When examining the situation I found it is now required to go to /system console and disable the console on the
serial port. After doing that, it is again possible to set the serial port speed.

However, when looking in the /export after that, this command:

/system console
set [ find ] disabled=yes

appears way down in the /export and the /port (same as above) still appears near the top.
So importing this config on a freshly reset router will still fail!

I have it working on ESXi but see above for an issue I have (the sequence of the ESXi interfaces is not the same as the ether#)

Maybe you have upgraded from a version around 6.42rc20? Then, this is indeed the problem that you will have.
You will need to re-install from the OVA or image!

hi guys, on my rb750Gr3 with firmware 6.42rc28 I wanted to mount a hotspot for a job. I can not install the user-manager package.

No. There is no usermanager for this router, also not for stable version.
It is unclear why this is, e.g. there is a dude (network monitoring) package for this router, so the smallish (low-end) type should not be the reason.
Anyway, you need another router type or use an external RADIUS server e.g. a Raspberry Pi with freeradius.
(which provides a lot more functionality than usermanager anyway, and you could use it to host a local webpage too)

Tue Feb 20, 2018 3:36 pm

Yes, there is 6.42rc changelog:
*) userman - added support for ARM and MMIPS platform;

Download MMIPS extra packages, there will be userman package in archive.

Installing 6.42rc30 from rc20 makes the RB3011 unbootable! See other descriptions of update bug.

Updated from rc20 to rc30, didn't boot back up. Resetting didn't do anything, so I had to netinstall back the stable. And that even only worked after three tries.

This is wellknown, no need to report it, read above. The problem is that rc20 won't update to anything. Not a problem with rc30 as you suspect.

Oh OK, I was under the impression that the problem was with updating from rc20 to rc24. Didn't know it was even worse than that.

Wed Feb 21, 2018 4:49 pm

Once more - if you upgrade/downgrade from 6.42rc versions below rc25 - you might (not will) experience issues. Does not matter which version you install. If you experience such problems, then Netinstall will be required. This is know problem which is already resolved. At the moment (after rc25) we have not experienced or received complaints about issues with upgrade/downgrade.

Hello. So now we can not use global variables in scripts called by or put as is in netwatch??? Is this by design now?? My scripts using global vars, now netwatch can not get/set values.
Yes, checked manuals, Mikrotik removed "policy" policy for netwatch scripts and global variables now can not be accessed. Seems like all global vars are "created by another users", so can't be accessed. Not the best upgrade IMHO...

@jmi2

short version: With this routerOS version, if there is single client with older card like CM9, then all other clients got no change to communicate without issues.
Simply if such client is connected to AP, then mobile and notebook have horrible connectivity and LG TV and hama radio got disconnected always after few seconds.

long version: Starting with 6.37 (actually already before, if previous FWs like 6.36.4 were switched to use wireless-rep) in combination with old HW like CM9, R52 on client side, wireless channel becomes useless for all (other clients of same AP and also clients of other APs on same channel). Same issue is still there with 6.42rc20.
...

original post here

Did you check different frequencies? I had two 912UAG-5HPnD and one 411U with R52 connected to another 411U with R52 at 5200MHz with one 912 constantly dropping connection. Can't completely rule out, that nothing else was using the spectrum at that frequency but scanning for wlans at 20MHz bandwidth didn't show anything. But changing to 5220MHz stabilized the connection

JimmyNyholm · Sun Feb 25, 2018 12:10 pm

Ok So I did see the wiki was updated to state the fact of HW offload on crs3xx series. So I did a new test and:

23 I H ether24                      bridge1                   yes   64     0x80         10                 10       none
24   H Core                         bridge1                   yes   64     0x80         10                 10       none
[admin@labb-mgmt-1] /interface bridge port>

Shurely it states that the Bond in my case named Core show hardware offload....
But!:

Setting admit only taged vlan, making it part of the vlans as taged member. Adding IP and accessing stuff works for most part from bridge to other but other to bridge sort of comes and goes.
I see one odd thing in the export:

/interface ethernet
set [ find default-name=sfp-sfpplus2 ] mac-address=6C:3B:6B:ED:F8:46
/interface bridge
add igmp-snooping=yes name=bridge1 protocol-mode=none pvid=64 vlan-filtering=yes
/interface bonding
add lacp-rate=1sec min-links=1 mode=802.3ad name=Core slaves=sfp-sfpplus1,sfp-sfpplus2 transmit-hash-policy=\
    layer-3-and-4

Why do the system change the mac'adddres one of the lacp member ports? the Unit should advertise its chassiID in its LACP BDPU's but then the individual links is surly individual links. There is, as far as I can se, in winbox or cli not any way to see the lacp state is this by design or misstake or is it not ready yet.

Could you please expose lacp states to cli and winbox!.

Edit: If I activate one port 1-24 on the bridge then the switch is reachable from bonding (sfp-sfppluss1,sfp-sfpluss2) but if I remove the cable from port 1-24 the switch does not answer from bridge bonding interface anymore. Is this a bug due to new hardware offload that bridge doesn't think of the bundle as to enable the bridge ip's.
@Mikrotik do you need me to create support case or is this relevant information to do you tests?

This works as expected with all interfaces that are not hardware offloaded lacp bonding the interface named Core is a bonding interface.

It does have a mac in running and that mac is what is being seen on arp lookups on other machines aswell.

jmi2 · Mon Feb 26, 2018 11:25 pm

@jmi2

short version: With this routerOS version, if there is single client with older card like CM9, then all other clients got no change to communicate without issues.
Simply if such client is connected to AP, then mobile and notebook have horrible connectivity and LG TV and hama radio got disconnected always after few seconds.

long version: Starting with 6.37 (actually already before, if previous FWs like 6.36.4 were switched to use wireless-rep) in combination with old HW like CM9, R52 on client side, wireless channel becomes useless for all (other clients of same AP and also clients of other APs on same channel). Same issue is still there with 6.42rc20.
...

original post here

Did you check different frequencies? I had two 912UAG-5HPnD and one 411U with R52 connected to another 411U with R52 at 5200MHz with one 912 constantly dropping connection. Can't completely rule out, that nothing else was using the spectrum at that frequency but scanning for wlans at 20MHz bandwidth didn't show anything. But changing to 5220MHz stabilized the connection

Sure, i tried multiple channels, also two bands, i tried to change nearly each wireless setting.
And once i figured out, that it's old card mikrotik with new firmware causing problems, i also did that one test, which confirmed, that routeros in this combination must be "flooding" air as with no very little useful traffic, it's capable to turn spectrum to totally unusable to other ap on same frequency. With older firmware all tests worked like a charm. See my full post.

wolph · Tue Feb 27, 2018 1:20 am

It seems that since the new firmware (6.42rc35) my capsman managed ap's can't get a dhcp lease anymore. All other devices in the network have no problems, but the mikrotik devices are unable to obtain a lease.

My logs are filled with:

feb/27 00:18:22 dhcp,warning dhcp1 offering lease x.x.x.x for C0:FF:EE:00:BA:BE w
ithout success 
feb/27 00:18:22 dhcp,warning dhcp1 offering lease x.x.x.x for C0:FF:EE:00:BA:BE w
ithout success

[edit]
Reprovisioning through capsman solves the issue temporarily. After a few minutes it goes back to the "without success" state.
The bridges have an admin-mac set and rebooting and resetting the devices makes no difference

Reverting back to stable and doing the same capsman reset immediately resolves the issue

Have you set admin-mac on the bridge?
I have only created the bridge1 interface.
<...>
what do you make of that?

/interface bridge
set bridge1 auto-mac=no admin-mac=6C:3B:6B:ED:F8:2E

And then recheck.

Chupaka · Tue Feb 27, 2018 10:08 am

Checking 6.42rc35, my L2TP/IPSec setup doesn't work anymore, connection stops at

10:50:58 ipsec Adjusting my encmode UDP-Tunnel->Tunnel
10:50:58 ipsec Adjusting peer's encmode UDP-Transport(4)->Transport(2)
10:50:58 ipsec encmode mismatched: my:Tunnel peer:Transport

Back to 6.41 - and it's fine again:

10:55:18 ipsec Adjusting my encmode UDP-Transport->Transport
10:55:18 ipsec Adjusting peer's encmode UDP-Transport(4)->Transport(2)

Settings are quite straightforward:

/ip ipsec proposal
set [ find default=yes ] auth-algorithms=sha256,sha1
/interface l2tp-server server
set authentication=mschap2 enabled=yes ipsec-secret=wonttellyou use-ipsec=yes

Can anybody check this?

Thanks, Chupaka. We will fix this in next versions.

pe1chl · Tue Feb 27, 2018 11:31 am

Please also fix the automatic addition of a DHCP client. It should only do this on first boot, when applying default config.
When there already is config (address, route) it should not create a DHCP client!

I suppose, you might have shrinked the disk, as normally (AFAIK) 128MB is the starting disk size of CHR in every type.
Or you started using CHR from the beginning, then 64MB was the starting size of the disk (as far as I can remember).
I can see 95+MiB total-hdd-space in every CHR I use, and 60+MiB free-hdd-space, so upgrade is always successful for me.

Probably, you should try resizing the disk of the CHR, then it might use the extra space, but probably, only the installation phase can resize the inner filesystem of CHR.

You should start from scratch, as stated in the System Requirements wiki, there 128MB of RAM and 128MB of disk space is required to operate/install CHR. You only need to copy out the current configuration, probably nothing more is needed.

Please answer a few questions about crs317.
1) will the switch be able to do vlan-remapping and outbound filtering(acl) ?
if the answer is positive, then when to expect it.

2) whether the switch forwards the qinq packets at wire-speed ?
if the answer is positive, how it is configured.

That is right, it is for CHR. Well, it appears to be a on-off problem, I did not see it in 6.42rc30 and it returned in 6.42rc35 but maybe that is pure coincidence.
It is a bit of a problem that the router suddenly obtains a new address and route that is not the configured one.

Well, Well, Well... With this latest release (6.42 rc35), IGMP-Snooping seems to be working correctly on a CRS-125 !!
Wow, what went right.

Seemed to make a difference (at least observed), after upgrading the firmware to rc35 as well.
It's been working correctly (for me), for over 4 hours... Never did that before..

There is something specific to your setup that is causing access to the CPU being lost. Please write to support@mikrotik.com, attach the supout.rif file and a small, simplified network diagram (preferably with device's model name on the other end).

You can also try disabling IGMP Snooping to check if that isn't causing the issue.

The script reads and writes private-pre-shared-key from "/ interface wireless access-list" and sends e-mails. Both actions require "sensitive".

Is it intended that 'on down' script is called each time a PPPoE client unsuccessfully tries to connect?

I have a simple script that clears VoIP connection tracking entries, to essentially force them to reroute and only want it to run 'on up' if the connection was previously down and only 'on down' when it was previously connected.

Since rc35 CAPs do no longer get an DHCP IP-address if the DHCP client runs on a bridge.

The DHCP server does see a DHCP request and replies but the CAP does accept the reply.
Tested with WAP AC and CAP AC.

kid-control:
hello guys, I do not know if I'm on the right page, since I have children at home I connect to the internet, I saw the kid-control utility, apart from the times and the mac address, you can also set custom dns that block adult sites?

thank you
valerio

pe1chl · Sat Mar 03, 2018 10:59 am

You can always configure OpenDNS as your DNS server, either as the DNS for the router itself and then advertise the router address as DNS server in DHCP
or by advertising the OpenDNS servers in DHCP, and then configure an OpenDNS account on your internet address with the settings you like.
You do not require kid-control for that.

Jotne · Sat Mar 03, 2018 11:32 am

You can always configure OpenDNS as your DNS server

This helps just for smaller kids. Larger kids understand what is going on, and set an other DNS server.
So you should also block other DNS server than the OpenDNS.
Even then they can use VPN and bypass OpenDNS DNS.

Chupaka · Sat Mar 03, 2018 11:47 am

Even then they can use VPN and bypass OpenDNS DNS.

That's why you should block any traffic in chain=forward and force using web proxy

pe1chl · Sat Mar 03, 2018 11:48 am

There is nothing you can do to really block things, it is only possible to do some shielding.
When you close your entire router they can use their 3G/4G connection.

tigro11 · Sat Mar 03, 2018 4:07 pm

or by advertising the OpenDNS servers in DHCP, and then configure an OpenDNS account on your internet address with the settings you like.
You do not require kid-control for that.

it's okay as you say if I want to screen all the traffic, even the adults.
I want to isolate children from filtered dns like norton, but adult traffic is open to everything. If it would be possible to insert custom dns on mac address kid it would be much easier.

pe1chl · Sat Mar 03, 2018 4:17 pm

It should be possible to do that! It should be possible have 2 DHCP server configs on your network, one with only static entries for the kid's devices
and one with the pool for all other devices, and then you can configure these servers with a different DNS address.
I did not try that, so you may encounter some hurdles.

You could also isolate the kid's network entirely (make a separate virtual WiFi AP with different SSID and password) and put a separate IP
range on it with different DNS server setup. I have a config like that running, not for kids but for guests. I have a separate guest WiFi SSID
that only routes to internet (while my own SSID is bridged to my LAN), and it has a separate DHCP server which advertises 8.8.8.8 as the DNS,
while my own network uses the MikroTik DNS resolver. This works without issue.

tigro11 · Sat Mar 03, 2018 4:37 pm

my idea was to use existing wifi and filter everything through mac address. Would you give me a hint on how I could do?
thank you

Jotne · Sat Mar 03, 2018 4:55 pm

When you close your entire router they can use their 3G/4G connection.

That is what I see too, so then you have lost the battle

Hello,

I've tried to configure bonding interfaces on the CRS326 based on the wiki entry:
https://wiki.mikrotik.com/wiki/Manual:C ... es#Bonding

When I try to add the ether interfaces to the bridge, I get the following error message:

failure: ether2 is already slave

The bonding interface is also not workling. I have tried to connect a NAS, where the bonding interface works fine with other devices, like a RB3011.
I'm using RouterOS Version 6.42rc37 in CRS326. Is this a bug?

When I try to add the ether interfaces to the bridge, I get the following error message:
Code: Select all
failure: ether2 is already slave

You should add the bonding interface, not the ethernet interface!

The documentation says add both.

skuykend · Sun Mar 04, 2018 5:19 am

The documentation says add both.

It's showing ether3 and ether4 also in the bridge as non-bonded ports as an example, but the bonded interface consisting of ether1 and ether2 is added to the bridge just as bond1.

You can always configure OpenDNS as your DNS server, either as the DNS for the router itself and then advertise the router address as DNS server in DHCP
or by advertising the OpenDNS servers in DHCP, and then configure an OpenDNS account on your internet address with the settings you like.
You do not require kid-control for that.
it's okay as you say if I want to screen all the traffic, even the adults.
I want to isolate children from filtered dns like norton, but adult traffic is open to everything. If it would be possible to insert custom dns on mac address kid it would be much easier.

With dhcp options and option sets you can define different DNS servers for specific users by mac address.

You are right, my mistake. But I don't get the "H" flag on the bonding device and it still not work. Also today I get the following messages on serial console, when I tried to reconfigure the bonding device:

MikroTik 6.42rc37 (testing)

Internal error: Oops: 17 [#1] SMP

Then I have tried to add an 802.3ad connection between CRS326 and RB3011. Interfaces coming up, so that I configured an IP address on each endpoint. It doesn't matter, ping does not work in each direction.

Additional it's not possible to configure MTU size on CRS326 on bonding interfaces. On RB3011 it works fine.

I suppose, you might have shrinked the disk, as normally (AFAIK) 128MB is the starting disk size of CHR in every type.
Or you started using CHR from the beginning, then 64MB was the starting size of the disk (as far as I can remember).
I can see 95+MiB total-hdd-space in every CHR I use, and 60+MiB free-hdd-space, so upgrade is always successful for me.

Probably, you should try resizing the disk of the CHR, then it might use the extra space, but probably, only the installation phase can resize the inner filesystem of CHR.

You should start from scratch, as stated in the System Requirements wiki, there 128MB of RAM and 128MB of disk space is required to operate/install CHR. You only need to copy out the current configuration, probably nothing more is needed.

Got a similar issue but I have a 128MB partition

Please please please do some work on IPv6!
E.g. following priorities from this posting: viewtopic.php?f=2&t=123302

Things I really need, the sooner the better:
- route marking and multi route tables using marks as in IPv4

Is this supposed to show under Terminal or via Winbox DHCP-Client Window row dispaly ? If its under window mine does not show the "D: flag as described for the release. If its under Terminal it does show up as in the Flags: row
My question:: when should the "D" flag appear under DHCP-Client? before the ip address has been assignend or after the ip addrsss has been assigned by the server?

To me CAPsMAN along with VLANs works in 6.41+, so can you open a separate topic for that and describe what you want to achieve? Maybe a workaround can be found.

Thanks. This will make it possible to configure stuff that I was waiting for.
Is there any plans for more learning modes. now there are Auto, On, Off.

[admin@MikroTik] > interface bridge port set learn=
auto  no  yes

No I do understand do not learn, static only check...
Yes I do understand learn end of discussion check...
But Auto? No but Yes? For Auto to make sence it would be accompanied with max-learn-hosts=[nr] being integer number from 1 to n and the option on-max-replace-mode=[none, fifo, lifo] and on-max-replace-timeout=[nr] sec.
With the learn being Auto and:
No timeout set honor only on-max-replace-mode
timeout set honor on-max-replace-mode and check that the timeout is reached before.

Am I right to be waiting for this aswell?

Thu Mar 08, 2018 4:46 pm

dksoft, biatche - This is still an rc version. The first step is to add such mode in regular wireless settings;
mozerd - As changelog entry states "winbox - show "D" flag..." it is a Winbox fix. Applies to, for example, DHCP client created by "detect-internet" feature;
kunago - Have you contacted support regarding this matter? If not, then write to support, explain the issue that you have and if it an actual software issue, then we will try to resolve it;

Q: How do you set the "default" option for "Unknown Unicast Flood", "Unknown Multicast Flood" and "Broadcast Flood" overall for an interface. It seems like dynamic interfaces (say an l2tp interface on the bridge) default to all flooding ON can you can't modify the options. I wonder if you can add a "Default Unknown Unicast Flood", "Default Unknown Multicast Flood", and "Default Broadcast Flood" option to the bridge, OR allow the ppp profile to set the bridge options similar to how you can set horizon.

Please would MikroTik consider allowing us to set granular pps (packets per second) filtering on ports, instead of percentage. 1% of 10 Gbps is still 100 Mbps, this would rapidly exhaust MAC address tables and take the network offline.

D-Link DGS and Netgear M4300 switches support setting most ports to selectively drop excess or shutdown port when exceeding eg 500 pps for customer facing ports, whilst having different values on internal ports.

Are there plans to provide dot1q-tunnel equivalent features and switch port rules to manipulate two VLAN tags? (eg pop outer and inner tags and replace them with others)

Please do this!! On our Extreme and Juniper switches we set PPS differently depending on the role of the port, e.g. ENNI's get very low limits, Trunks get very high limits, Servers get high limits, Edge devices get very low limits.

Now the switch on vlan64 will get ip and can access everything it should. But nothing from the upstream device can access the bride not by mac nor IP.
If i then check the connection by connecting a laptop to ether1 this laptop gets ip from upstream dhcp and all works AND the bridge itself is accessable from upstream on other device(winbox l2 or l3).

The minute I disconnect the laptop (ether1) so that the only active port in bridge is Core (lacp hw bond/trunk) then the same upstream system can't access the bride no more through any l2 or l3 means in winbox. It is seen still but can't login.

Exactly... The CPUs in CRS class devices are weak, extremely weak. I assisted someone recently that couldn't do 10Mbps routing on a CRS125, as this was software based.

I would like to see more high end merchant silicon implementations. Broadcom Dune, for example, was released in 2015 and provides 800 Gbps forwarding capacity per device, VXLAN, NVGRE, Geneve, MPLS, VPLS, hierarchical traffic manager with support for thousands of flows and external DDR4 or GDDR5 packet buffering support.

People are excited about CRS326 when a 4 year old D-Link DGS (8x1Gbps UTP, 24x1Gbps SFP, 2x10Gbps, dual power) switch does everything wirespeed and supports (R|M)STP, QinQ, dot1q-tunnel?

Mikrotik should work on their RouterOS 7 unicorn, these functions are missing and sorely needed:
- IPv6 blackholing
- Per interface rp-filter settings (no reverse path filtering in IPv6 at all currently)
- MPLS for static or BGP routes
- BGP multi-protocol support (IPv4 BGP sessions that exchange IPv6 routes and then switch traffic using MPLS labels)
- IPv6 MPLS
- VirtIO NIC multi-queue support
- Integrate the high-availability work that community members have done. Most people would probably purchase pairs of CCR devices if they could simply connect a heartbeat cable and enable a feature.
- Proper VRF isolation and working trace routes
- IPv4 and IPv6 feature parity (NAT (even just 6to6 or prefix translation), connection tracking, etc)

I've been using QinQ trunking in software bridges on a hex for sometime now. Nothing really special to report about it. I imagine it's software switched but for me that's not a problem.

Exactly... The CPUs in CRS class devices are weak, extremely weak. I assisted someone recently that couldn't do 10Mbps routing on a CRS125, as this was software based.

Well the CPU is weak, but not THAT weak. To have that problem you would have to do IPsec or extremely lot of (and badly ordered) filters.

However, a CRS is NOT a replacement for an L3-routing switch as available from A-brand manufacturers (HP Procurve / Aruba Networks, Cisco etc).
Those switches do wirespeed routing just like they do wirespeed switching, and a CRS simply cannot do that.

My position remains, when you require a professional switch with wirespeed L3 routing and other facilities available in that range (DHCP and ARP snooping/filtering etc)
then do not buy from MikroTik. MicroTik has some nice low-end switches that can do some routing but it is only intended for management and/or some special use
case, not to route the main traffic of the switch. And it does not offer many of the facilities available on those professional switches.

Maybe it will change in the future, but hey, maybe in the future we'll also get RouterOS v7. However, that does not seem to be the near future.
So for now, buy CRS only when you need mainly plain switching and no advanced features.

Went from 6.42rc24 to 6.42rc41 and it broke my dual WAN configuration, its similar to this configuration except I am just using 2 WANS with a 3:1 ratio, ie one WAN gets more traffic. https://aacable.wordpress.com/tag/mikro ... wan-links/

Cannot roll back either or force a downgrade for some reason.

Would resetting the configuration and downgrading work? I don't know why the downgrade just fails. It just reboots and I am stuck on 6.42rc41

*) crs326 - fixed known multicast flooding to the CPU;
*) dhcp - improved DHCP service reliability when it is configured on bridge interface;
*) ssh - generate SSH keys only on the first connect attempt instead of the first boot;
*) ups - improved disconnect message handling between RouterOS and UPS;
*) wireless - enable all chains by default on devices without external antennas after configuration reset;

If you experience version related issues, then please send supout file from your router to support@mikrotik.com. File must be generated while router is not working as expected or after crash.

Note that release candidate versions are published strictly for testing purposes and should not be used on production routers.

*) ssh - generate SSH keys only on the first connect attempt instead of the first boot;

Could you please comment on why this change was made?

Is it not better to generate these at startup than to make an user wait the first time he connects?
Specifically on older boards (with single-core 400MHz CPUs), this generation can take a long time.

Lets say I power-on a new router , or a router that has been reset to empty config.
It's way more comfortable for me for that router to generate its SSH keys while I might be clicking doing other things, rather than make me wait when I want to connect.

My guess would be that routers are powered off-on during initialization when it takes so long, and configuration gets inconsistent resulting in complaints or returns.

Tried 6.42rc43 and found nice visual bug:

Under System -> Routerboard I can see factory ROS version, while under System -> Resources it is blank field.

Any SIM slot control button still there even that RB951G-2HnD have no such slot. Funny to see this suddenly appeared "feature".

eworm · Fri Mar 16, 2018 12:09 am

Under System -> Routerboard I can see factory ROS version, while under System -> Resources it is blank field.

One is RouterOS version, the other is boot firmware version.
Looks like older devices do not have a record about factory RouterOS version.

Good afternoon.

Such a problem - 6.42rc43 +hAP AC^2 = boot loop. If you roll 6.42rc43 and do not update the firmware, everything seems to be fine, but it's worth updating the firmware and the router stupidly goes to the boot loops. At the same time, I tried to download a stable version via nethinstall, but there is still a loop.

If the router reboots from the button (pull out the button, hold down the button, insert the PS and wait for 20 seconds, the router allows you to go through the winbox, but if you just reboot or turn it off / on, it's a loop again.

I was able to roll back to stable firmware in this way - installed 6.41.3, then rebooted from the button to the factory, connected to winbox and rolled firmware by pressing "update firmware" several times and then rebooted the device.

So it goes.

Sincerely.

tomaskir, pe1chl, 105547111 - Waiting time is not too long. This kind of implementation will satisfy the biggest part of the users so we decided to re-make this generate process.
upower3, eworm - This is not a bug. If router was installed in factory before we introduced this feature "show min RouterOS version", then this value is not specified. These are two different variables - RouterBOOT and RouterOS minimal supported versions.
Keyko - We will look into this problem and fix it as soon as possible if we managed to reproduce it. I recommend that you still contact support@mikrotik.com regarding this problem so you can get more feedback from our side and reach solution much faster.

But what is the benefit - what was the original need to change this?

Because from what I can see, this has only disadvantages.
Making users wait when they want to connect is NOT a good UX.

The big problem on CCR1072 with 6.42rc43 (Release candidate)
After the upgrade, all 10g interfaces were lost! Only 1 gb copper is still visible. Reset did not help.
I had to roll back to a stable 6.41.3

atlanticd · Sat Mar 17, 2018 3:14 pm

Hi strods, Keyko,

I experienced the same on my hAP ac^2. I upgraded from factory 6.40.5 to 6.42rc43 using netinstall (netinstall version was also 6.42rc43). After successful update, I triggered firmware upgrade in Winbox by clicking on Upgrade button on System/Routerboard menu. After upgrading the firmware to 6.42rc43, the boot loop started. I tried to install with netinstall and RouterBOOT "15 seconds" method 6.41.3, again 6.42rc43, and lastly 6.40.6, and although install was always successful, the boot loop still remained. In the end I recognized that even without pressing reset button while plugging in the power, it always went to RouterBOOT (I saw it in netinstall Ready state always). Finally, I reverted by RouterBOOT "5 seconds" factory reset method to boot, that booted properly RouterOS 6.40.6 (the last I tried with netinstall), and I saw that current firmware was 6.42rc43, and Upgrade firmware was 3.43. Here is a screenshot:

Once I clicked on Upgrade, and after reboot, I could properly boot again. And upgrade again to 6.42rc43 (and of course this time I skipped firmware upgrade, so it is running now with ROS=6.42rc43 and RouterBOOT 3.43)

So steps to reproduce:
1. Upgrade from factory firmware to 6.42rc43
2. Upgrade firmware to 6.42rc43
3. Bootloop start to happen

Revert:
1. Boot the device with "5 seconds method" : Hold this button during boot time until LED light starts flashing, release the button to reset RouterOS configuration (total 5 seconds)
2. Trigger Upgrade (which is actually Downgrade) of RouterBoot firmware

Kindly ask you to investigate this issue. Thank you.

Good afternoon.

Such a problem - 6.42rc43 +hAP AC^2 = boot loop. If you roll 6.42rc43 and do not update the firmware, everything seems to be fine, but it's worth updating the firmware and the router stupidly goes to the boot loops. At the same time, I tried to download a stable version via nethinstall, but there is still a loop.

I'm getting this error "no such item (4)" when enabling or disabling the pppoe client interface. Router is RB750Gr3 6.42RC43.
Note that this problem is not unique to 6.42RC43. I've encountered it before. It's just that I've only started looking into it now.

If I do a "/interface disable pppoe-out1 " then wait more than approximately 16 secs, and do a "/interface enable pppoe-out1 ", I will receive the error "no such item (4)".
Less than approx 16 secs, no error.

If I try the above with an ethernet port, no error.

Same thing happens on an RB2011UAS-2HnD running 6.42rc41.

Not a big problem, more of an annoyance, during normal use but wreaks havoc with scripts that takes longer than 16 secs between disabling and enabling the pppoe-out1 interface.

Update regarding 6.42rc latest release:

We have made a potentially significant improvement for wireless Nv2 PtMP configurations in the latest 6.42rc version release.

Those of you who are willing to test rc versions on your test network, please upgrade to the latest version, test the performance and report to support@mikrotik.com with the results. Your effort and feedback will be highly appreciated.

Please note that rc versions are released strictly for testing purposes and should not be used on crucial network devices.

We have made a potentially significant improvement for wireless Nv2 PtMP configurations in the latest 6.42rc version release.

Before such protocols are of any use to us, we need you to implement airMAX, the other guys to implement NV2, or you both agree
on a standard that both can implement. We invariably have a mix of different manufacturers of user equipment and now can
only use bare 802.11 or it will not be compatible

All the changes are on the AP side so you need to upgrade the AP. Client version can stay the same.

Hi strods,

I can confirm that the RouterBOOT firmware upgrade to 6.42rc46 works, and it is not causing boot loop anymore. However I noticed that after firmware upgrade (and only after Firmware upgrade, not ROS upgrade), the total memory and free memory shows much less than before. Instead of ~256 MB now it is ~128 MB.

              
              free-memory: 79.1MiB
             total-memory: 106.3MiB

I reported earlier in another topic that interestingly my hAP ac^2 unit came with 256 MB unexpectedly, and a colleague from MikroTik support stated it that some unit came with more memory. Can you confirm that MikroTik now limit by intention the available memory in this new firmware just to meet the specs, even though the unit has more memory physically, or was it a software bug?
Thank you.

I am having trouble with setting up a CAP AC using the 'quick setup'. Everything was fine until I rolled the last couple of RC updates. I am trying to set up as 'Home AP dual', and configure as before. However it refuses to get an IP address and then I cant access the device thought winbox as it refuses the connection. This then requires a manual reset if the device, but nothing seems to work when setting up with the 'Home AP Dual' quick settings. I have internet back now by using the 'WISP' quick setting and configuring that....

I am a no expert, but it's strange I had no problems from a few RC versions ago.

Not what you ask for, but you can send you log to syslog.
Install Splunk and you get an amazing log tool for your Mikrotik.

I saw the Splunk installation, but I tried not to commit a machine to mount the Splunk server. On PFsense I use NTOPNG, unfortunate that on mikrotik you can not install as memory could be used or USB sticks or better still the Micro SD. I need it because I have to keep track of the surfing of my hotspot. If you have a solution to track without engaging a computer as a log server it would be a great thing
now i use this solution.

Synology NAS can do it if you install the Log Center package and configure it as the syslog destination for your Mikrotik. QNAP probably does something similar.

How do I tell RouterOS how many queues I have allocated on the hypervisor or does RouterOS set them equal to the number of CPU cores?

Chupaka · Tue Mar 27, 2018 7:06 pm

Per CPU, I think. Check with

/system resource irq print where users~"virtio"

dksoft · Tue Mar 27, 2018 11:25 pm

Per CPU, I think. Check with
Code: Select all
/system resource irq print where users~"virtio"

Good tip, thanks.
It does automatically detect how many queues are configured. No need to change anything in RouterOS.

I know that there are some problems in the WiFi section of hAP ac^2. There are significantly improvement with V6.42rc52, however, this is not enough. Please take at take at the following figures:

iperf Done.

The figure shows very good. However, when we attempted to carry the actual file download tests, it turns out very dissatisfactory.

hAP ac² file transfer test
310.66MB file

V6.40.5 310MB （92s）27Mbps
V6.40.6（bug fixed) 310MB (82s) 30Mbps
V6.41.3 (stable) 310MB (124s) 20Mbps
V6.42.RC52 310MB (3s) 826Mbps
V6.42.RC52 310MB (30s) 83Mbps
V6.42.RC52 1.64GB file (147s) 89Mbps

hAP ac lite 5G WiFi file transfer test
V6.40.6 310MB (28s) 89Mbps.

Also I carried out the Mikrotik bandwidth test on both hAP ac^2 and hAP ac lite.

hAP ac^2 5G WiFi

hAp ac lite

Can anyone tell how comes the differences of them are so big?

When you compare tests made with different tools (e.g. iperf VS. CIFS) you have to be aware of behaviour of test "tools". Tests done using iperf are not affected by latency much (apart from usual TCP slow-start) while some more "chatty" protocol (such as CIFS file transfer) can be affected by larger latency quite much.

In your particular case one needs to know what was latency during CIFS test (and latency with idle connection) and it might become quite obvious why CIFS shows so much worse results than iperf. Or it might not.

I work for mobile network operator and when we are measuring pure radio performance, we allways use iperf (and UDP). If such "raw" test shows good performance, then the rest is lost elsewhere, either other parts of network or is artefact of application. One example of application affecting tests was when using Ookla Speedtest on Android: we were consistently getting much worse results when running Speedtest directly on smart phone than when running Speedtest on laptop with USB tethering between the very same smart phone and laptop. We attributed the difference to the fact that phone's CPU was unable to process all data in due time. We also observed negative impact of app when testing latency. Speedtest, run on laptop, was giving us say 30ms RTT but we were able to show that reply from server arrived into the laptop after say 22ms ... but app took another few ms to process data. We couldn't say when additional delay occurred (at TX or at RX or both), but that's about how correct tests can be.

With the Unknown Unicast/Multicast Flood disable button being added in to the bridgeports, is there a way we can get that added to PPP profiles similar to bridge/bridge priority/cost/horizon? OR have a bridge-wide default option for it to be either on or off? I'd rather it DIDN'T default to "on"

Thanks

Thank you very much for responding my post. Based on your information, I have already learned more about network bandwidth, throughput, and latency.

Based on the results of MikroTik Bandwidth test on hAP ac^2 5G ac and hAP ac lite 5G ac, they show that the firmware V6.42RC52 on hAP ac^2 has to be finely tuned to achieve a stable and nearly flat performance otherwise the sales order for this product will drop tremendously due to poor and unstable performance.

In summary,

1. Bandwidth - can be determined by iperf3, MikroTik bandwidth test

2. Throughput - can be determined by actual file transfer or the equivalent area in MikroTik bandwidth Test

3. Latency - can be determined by ping command.

Is there any bug? DFS searching time is 10minutes ??

I also have Mimosa and there the DFS even takes the network down longer. Up to some 15-20 minutes. Partially also because when the AP if 'free'd' from the DFS it takes a long time before clients are associated back and in full running mode again. Actually, if your Mimosa P2MP network is hammered by DFS you might as well not use is it at all....... completely unusable. You have to find a band/channel that has no radar or no DFS restrictions. Only then it works. (there is no way of avoiding DFS in Mimosa product line, as we can with MT.

I understood it.
I'm playing with capsman ant 5 access points, At first time I did not understand why there is no wireless connection...

But I think it will be better if in satus window will show not only detecting radar but countdown timer, so you will known exactly when detecting will end.
