The CCR2004-1G-12S+2XS looks promising. I would like to see some speed test results of GRE and EoIP over IPSec. With the current generation of CCRs (TILE) the results of using plain ipsec and tunnel over ipsec differ by a mile.

Will CCR2X series come out straight with ROSv7 or will it be part of the v6 family first?

Do you have more information about that Annapurna AL32400?

Unfortunatley every time MikroTik features in a Linus Tech Tips video he never gives the product the showcase it deserves, makes me wonder if he really understands it! After watching their 10 Gbit home network video a while back and they were having trouble figuring out how to configure it/couldn't find winbox so the video just cut to when it was done lol.

Do you have more information about that Annapurna AL32400? E.g. how many cores?

It has four cores. See here for details of CCR2004:

Only 4 cores for such a huge amount of SFP+/SFP28 interfaces... Is there any other way more powerful version on the roadmap?

Well, looks like the CCR1016-12S-1S+ is pretty much dead now. But the test results have me scratching my head. Either a box is PPS (CPU)-bound, or it is IO-bound. Looking at the block diagram, you can push a maximum of 50 Gbps through it (port extender uplink to the SOC is 2x25G).

Yet the box maxes out at ~2.8 Mpps fastpath at 1518 byte packets, giving ~35 Gbps. As that isn't really close to 50G, it looks it's CPU-bound. But going to 512 byte packets, the PPS more than doubles to 6.2 Mpps, showing that it wasn't. Going to 64 byte packets the PPS again goes up by a factor of 1.5 to 9.2 Mpps. So if it can do 9+ Mpps, why can't it get closer to 50 Gbps at larger packet sizes?

And at 35 Gbps going flat out the box is oversubscribed by a factor of 5. And that's in the absolute best case. If you want it to do anything more than just slinging max size packets, it's going to be closer to a factor 30. A CRS has the excuse that it's a switch (and can do L2 at speed) for L3 oversubscriptions like that, but this is supposed to be a router... I can see it being a VPN concentrator or BGP RR, but you don't need the 25G (or even most of the 10G) ports for that.

I'm not really getting this, to be honest.

Good to see a desktop version of the CRS3XX line. I need the CRS112-8P-4S-IN upgraded to the CRS3xx hardware and have 16 ports, rackmount or desktop (short depth PoE switch).

Linus is a nice dude that honestly likes technology.
But when it comes to networking he simply doesn't know much about it. (Check an old Infiniband video that he did that shows clearly the lack of knowledge on networking)
So I don't expect him anytime soon to give RouterBoards and RouterOS the attention they deserve.
Even STH don't seem to show what the platform can actually do.

Anthony is probably the only guy in LMG that can understand complex network stuff (but doesn't necessarily knows them in advance).

Besides, their (gaming) audience is not that advanced to even understand what RouterOS can actually do.
They obviously prefer RGB

Why are you making these black cases? Well, couldn't you have made a normal case for hAP AC3? Like the hEX S by color, or classic white? Again, this "cheap" case as in the "lite" version.

Could it be a mix? The only part of the packet that uses CPU power is the header, the payload is just using memory bandwidth. Maybe with the 1518 byte packets its memory is bandwidth starved, and the CPU isn't maxed out. When it get smaller packets we use more CPU - as the payload gets smaller - than memory bandwidth. This way we don't have a smooth curve, as we are used to see.

Going down to 64 byte packets, it finally gets CPU starved - and we see the pps and bps falling.

Yeah, but that's not what happens. If we assume that 35 Gbps is an IO limit (not due to the interconnect but something else, like memory bandwidth for instance as you say), the 64-byte result proves that the CPU can do 9.2 Mpps. Then why isn't it doing 8.5 Mpps to get to the same 35G at 512 bytes? The CPU can do it, as it proves when shuffling 64 byte packets, and the IO subsystem can, as it proves with the 1518 byte packets. Yet although PPS goes up, total BPS goes down for both 512 & 64 bytes. That makes no sense; it isn't hitting either IO or CPU limits yet at 512 bytes.

When you look at the results for other boxes, like the CCR1016, they behave more or less like you would expect; either 1518 bytes IO bound (by combined bandwidth of the physical ports) and 512 & 64 bytes CPU bound with roughly the same PPS and lower total BPS, or 1518 & 512 bytes IO bound with roughly the same BPS and 64 bytes running out of CPU with higher PPS buth lower total BPS.

If I remember correctly, these tests measure the speed of the payload traffic, not the speed at ethernet layer. That would explain the difference: due to the header overhead it hits the (theoretical) 35Gbps ceiling.

Hello. Interesting point of view about the performance.. what about a comparison between the 1036 and one of these in terms if pure speed? We use 1036 at core with 4.5 gbit per second fastrsck with cpu 15%... this new router seems interesting so i can avoid a switch for trunk in 10g ports, but the max throughtput will be lower...

Nice products for this newsletter. I would love to see Mikrotik on the CRS3xx line to have PoE+ included, and mGig Ports instead of normal 1 Gbps ones. That will make this switch (and the rack mount version a very compelling device.

Still I like the new CRS326 desktop version but the next level for me will be to have these features out of the box.

Will CCR2X series come out straight with ROSv7 or will it be part of the v6 family first?

Do you expect an answer from MT on this? They will not respond.
My guess, no, v7 is in early beta stage.

If I remember correctly, these tests measure the speed of the payload traffic, not the speed at ethernet layer. That would explain the difference: due to the header overhead it hits the (theoretical) 35Gbps ceiling.

That's not what the test results indicate; 1518 bytes is a full 1500-byte MTU Ethernet frame, and the BPS & PPS rates match those 1518 bytes. So do the other two, where 64 bytes is of course the minimum Ethernet frame size. So in the published numbers the entire frame is counted, not just the payload.

True. Time to find a new hypothesis. But it is clearly hitting some limit, and I don't think it is software related.

What irony in NEWSLETTER you show a photo of Nexstream employees from mikrotik sxt lite5 with software from .... Cambium.
During the epidemic, it is very clear how much MIKROTIK suffers from the lack of a good p2mp protocol. Any AP where many clients have launched a home VPN // Video teamwork almost ceases to work 802.11AC + RTS / CTS completely fails. NV2 supports only 20Mhz channels with full scaling and only 20-25 clients without any degradation of spectral performance.

Very surprising to me that launches another indoor LTE device. The most incredible is that all indoors are more expensive that the outdoors models.

Regards.

@krafg: Me to. The focus on LTE SOHO boxes generally confuses me. That market is already flooded with cheap alternatives.

No news about spectral scan o mu-mimo?

dear MikroTik,

on regards of CRS326-24G-2S+IN, it's nice if you can create CRS326-24G-2S+2HnD-IN (the upgrade of CRS125-24G-1S-2HnD-IN). this unit also can help the MTCSWE class as the switch crs3xx will have the internal wireless to be able to connect to the trainer router. Or may be create the smaller version like CRS317-16G-1S-2HnD-IN or similar.

thank you

Paul

@prawira: Why just not buy a simple access point? 99% of all switches ends up in a closet or rack - what's the point of wireless then? Wireless is also more prone to technology changes (n, ac, mimo etc.) but a switch remains.

Why is the hap ac3 so more expensiv than the hap ac2. only an additional lte mode can not justify +150€, or?

mikrotik is never going to carry out a spectral scan?

Any plans/timetable for UNII-2 support in the US on RBwAPG-5HacT2HnD? I just switched all APs to these and was disappointed they were not on the list of supported products listed in the newsletter.

Just a suggestion / HW feature request:
all fanless future products should also have the possibility to optionally add a cooling fan, ie. a power source for it should be available on the board.
MT can put such add-on and replacement cooling-fans also into its product portfolio.

Why is the hap ac3 so more expensiv than the hap ac2. only an additional lte mode can not justify +150€, or?

good question, for 140 EUR you get Huawei B715 cat9 modem + hap ac2 fo firewalling/routing

Where is Wifi 6E?

many reasons of the need of build-in wireless option on switch...
1, for the mtcswe class where no network cables from trainer router to students router. with add another access point means more complicated setup, as more cable and need more power plug for it.
2. with the condition where the switch located on top of roof and no celluler signal available, than the engineer can do the communication with noc within the build-in wireless on the switch.
3. remember CRS is router and switch as well, it can do routing as well; not just switching. so wireless still need for indoor / desktop. as state before, additional access point means more complicated setup as more data and power cables; thus reduce 1 port on switch for the additional suggested access point.

cheers

hi
i have a problem on LHG XL hp5
lhg ethernet port not compatible with any switch ,when connect the ether to any switch will cause loop into switch,even when i use a mikrotik rb951 as aswitch by bridging it is ports,rb951 log say ethernet4 (lhg connect into) on bridge1 rseve pakit with it is own mac.........loop.
_____________________________
LHG config
bridge1=>ports=>(ether1+wlan1)
wlan1 config
staion-wds

Because of this problem I bought a new device (LHg) but the surprise was the new device suffers from the same problem,
I tried in all ways and with all releases of ruoteros but I surrendered now and I came to ask for help
____________________________
SOLVED
the problem solved by using A little trick

LHG XL Hp5 config
bridge1=>ports=>wlan1 . . . . . "wlan1 mod staion-wds"
mesh1=>ports=>bridge1+ether1 ............. this is my little trick mesh Contain bridge as an aport + ether1

I too am super-interested in UNII-2 support in the US, especially for the Audience/RBD25G-5HPacQD2HPnD. Being able to leverage UNII-2 for the mesh network at 160MHz is the spectrum flexibility we've been needing!

Also the RBwAPG-5HacT2HnD-US APs as well. These are "primary devices" in a business infrastructure.
Unfortunately, the power and flexibility of the Mikrotik wifi ecosystem is terribly limited in the US.

We really, desperately need UNII-2 in the US to use these things in serious facility deployments; having 57% of the available spectrum 'locked out' due to lack of FCC device-approval makes Mikrotik a non-starter for anything other than simple home deployments in the US (point-to-point things are obviously still very much on the table).

We are actively working on other UNII certifications, including for Audience. Other already certified products are listed in the newsletter.

Thanks Normis!
I appreciate your response and I know you are! I just wanted to add public feedback in support of it! "Squeaky-wheels get the grease" and all...

Where is Wifi 6E?

Hopefully it will go away.

• CRS326-24G-2S+IN

@normis, what's the big difference, if any, between this new CRS326-24G-2S+IN and the CRS326-24G-2S+RM, besides the case?

I spotted the following difference in their respective download directories:
https://mikrotik.com/product/crs326_24g ... -downloads has a "RouterBoot firmware" for download (file tilegx_3.41.fwf ),
whereas this is missing for the RM version:
https://mikrotik.com/product/CRS326-24G ... -downloads

How come & what does this mean?

dear all,

i just find out that netPower 16P is CRS318-16P-2S+OUT.
so, we suggest mikrotik can release CRS318-16P-2S+IN-2HnD

Yes, this could be the update to the CRS112-8P-4S-IN.

When Cube 60 will be released with 1gbit ports?

Dose anyone know when July 2020 Newsletter will release?

Most likely last week of July or little later
