Anyone else find that the enclosure for this case acts like a sound amplifier? I no longer have one of these switches in my attic. Instead they are in living spaces of my home, where the noise profile is more important. I used them without fans for a short period of time, but then I needed to instal...

Attics get surprisingly hot baking in the sun. Much more so than most people would assume. The heat kind of gets trapped in there, especially if you like most people - have a black roof, poor/no ventilation and all of your insulation in the attic floor to insulate the living spaces below It's worse ...

Well, I wanted to make this work, but I got to the last day of my return window, and I had not yet been able to resolve my issue, so I decided to send them back. I have popped my old Unifi 802.11ac units back in for the time being (and all the VLAN's work great again). Going to have to think about w...

holvoetn , so, if I want to congfigure guest network (separate SSID with custom name, security, channel, VLAN ID, etc.), and my basic VLAN ID is 1, Iam just can make datapath config with VLAN 1 for main network and, for example, datapath config with VLAN ID 2 for guest network, and all will works f...

So, as recommended in this other thread with a very similar topic I went back and reset the CAP ax units to CAPSMAN mode. I then re-paired them with CAPSMAN on the CAPSMAN device. I applied my main SSID config and security profiles. So far so good. Main SSID works. In CAPSMAN I added slave interface...

Caps mode is configuration. So don't use No Config. Then you don't even get caps mode. According to documentation: Default ether1 will be set to DHCP client, ether2 will go to bridge with wireless interfaces. All wireless interfaces listening for capsman controller. No firewall, no NAT, nada... But...

Also as a reformed UNIF--KER... I was bit hard by the shortcoming of Mikrotik's AC radios. I did a few hundred caps-man system, but configured 1 cap system with the WAVE2 drivers, and that was the end of that. Caps-man is awesome in concept and gives you instant info about roams and stuff... but Mi...

This part of the documentation should be sufficient:

https://help.mikrotik.com/docs/display/ ... Fi-CAPsMAN:

When interested, only read the part of the wifi-qcom driver beneath.

I will take a look, thank you.

From what I know and have red: - cAP ax: reset config and set it in CAPs mode (this is enough) - CAPsMAN: config datapaths with corresponding VLAN id's Use a hybrid port with management VLAN untagged, Corporate and Guest tagged. Don't use VLAN id 1 (implicitly or explicitly), when using VLAN's. Jus...

Alright, so please bear with me here. I just bought two CAP ax units. I have no idea what wifiwave2 is (and neither my google search results nor Mikrotiks documentation is helping), but I joined them to CAPSMAN on a separate routerOS 7.14 device. I tried pushing vlan to slave devices using configura...

Hi everyone, First off. I am no stranger to VLAN's and networking. I started playing around with this stuff on my old ProCurve switches in the late 2000's and since have successfully configured on ProCurve, HP, Aruba, and Mikrotik switches, as well as Unifi AP's and controllers, as well as managing ...

One POE port powering a third party wireless AP on my CSS106-1G-4P-1S has gone from working fine under 2.13 to reporting a "short circuit" under 2.16. Nothing else changed in between. Working -> update -> short circuit (15s later, after reboot) Anyone else having similar issues? Any sugges...

CAP AX judging by the specification can not power CRS326-24G-2S+ it does not have enough power even if you use a power supply at 30V, the maximum you can supply 18W, and CRS326-24G-2S+ consumes up to 21W. From a standard 24V power supply can deliver 14W. Indeed. I misread the specs. That is a shame...

Hi everyone, I was reading the cAP ax specifications . It claims max bandwidth at 5ghz of 1200Mbit/s and a max 2.4Ghz bandwidth of 574 Mbit/s. Now, I am no beginner when it comes to WiFi, and I know these max figures are rarely achieved in real life (and are half duplex at that) but theoretically wh...

This issue is related to the design of the S-RJ01 module. We had to rip them out using force during our last migration, unfortunately in some cases damaging the switchport (or NIC) they were in. While I am glad to hear it is not just me, I'm sad these are wrecking SFP+ ports. I was able to remove m...

As title says. Here is what I am looking at in SwOS: mik_fan.png Is this normal behavior for this switch, or did I get a switch with a dead fan? I can confirm that I cannot feel any air flow from the leftmost (from the front) fan hole, but I can feel it from the other two. It is also worth noting th...

Is anyone else having this issue? For my main rack switch it was beneficial to have a split of ~12 gigabit copper ports and ~12 SFP+ ports, but since no such switch existed, I just splurged for one with 24SFP+ ports (CRS326-24S+2Q+) and just grabbed a bunch of the S-RJ01 modules. At $37 each they ar...

Hi Everyone, Just picked up a new CRS326-24S+2Q+ and I am struggling a little bit. I'm using it as a layer2 switch + VLAN's with no routing, so I opted to boot and use it in SwOS mode. I am using 3M Molex DAC cables to connect the Fortville (Intel XL710-QDA2) NIC's in my servers to the switch. I wen...

Hey everyone, So I am currently scheming replacing my three aging Unifi UAP-AC-LR units with a Mikrotik setup.

Hey Everyone, Got a ~3 year old CRS317-1G-16S+RM. Walked by my rack today and noticed a bright red "FAULT" light. Upon some investigation one of the two fans is at 0 RPM. I think I am out of warranty (but I can't seem to find how much warranty I actually had anywhere), so it looks like I a...

I'm curious if there is any information out there that I may have missed. My network is currently largely 10gig SFP+ based but I am considering moving to 25/100gig. I feel like in 2022 I don't want to invest in a dying standard in 40gig SFP+ The CRS354-48G-4S+2Q+RM would be absolutely perfect for my...

I guess no one got back to you on this? I myself am trying to configure LACP in a similar way and trying to figure out the best way to do so. Unfortunately not. Since this incident, I just disconnected one of the two links, and have left it that way. Thus far it hasn't become blocking with my load,...

With no other details, my first guess is that you are creating a loop that is not configured properly for a LAG on one end or the other. At least until you get the LAG working, enable RSTP so that at the least the loop will be killed quickly. I can tell you that LAG does work on the CSS326 (I have ...

Hey all, My main switch in my rack is an CRS317-1G-16S+. I also have a CSS326-24G-2S+ in that same rack, for gigabit copper stuff. I wanted to link up the CSS326-24G-2S+ to the CRS317-1G-16S+ using both of its SFP+ ports in a LACP configuration in order to get almost non-blocking performance on the ...

Hi All, I recently upgraded my CRS305-1G-4S+ to SwOS 2.12. Prior to the upgrade my SFP-GE-T 1000BaseT SFP modules were working perfectly.

Alright. I see we have a few "gaming" home PC builders here. Firstly, the "rules of thumb" of gaming PC building do not apply to switches. Even if they did, a lot of people spread dumb "rules" out of ignorance in the PC gaming communities. 1.) From a "safety" ...

All the clients attached to the secondary switches are gigabit only. I have a large number of RX pauses on the SFP+ port on the CR...

My CRS317 under Swos appears to be reading the temp of my Finisars accurately at 40C. Problem is CPU is at 35C, but because my finisars are at 40C, the fans are kicking on. Why is th efan trigger so low? The specified temperature range on these transducers is -5C to 70C. Seems silly to kick the fans...
