Re: CAPsMAN errors in log

Possible causes:

1. poor network connection between capsman and caps
2. high cpu load of capsman

Re: How to evenly distribute clients in capsman?

If APs placed in same location, use load balancing group for distribution between balanced APs.

Re: Does CAPsMAN controlling radio channels and interference betweens

Does not matter, as it is called, (management or control)) the result is the same: cAPs select different channels to avoid neighbours interference.

Re: CAPsMAN

2011 can serve up to 70 cAPs in capsman forwarding mode and up to 400 clients at same time, with 40-60% CPU load. Download speed make no matter, if capsman is a simple bridge (routing, queuing, firewalling ets served by another hardware), overwise you should keep in mind this workload.

Re: hotspot + CAPsMAN

Create hotspot on CAPsMAN, with capsman bridge as hotspot interface, will be fine )

Re: Does CAPsMAN controlling radio channels and interference betweens

Yes, CAPsMAN use DFS channel management by default. Some configuration tweaks for channel selection restriction may needed.

Re: CAPSMAN disconnects sporadic all caps interfaces

Seems CAPsMAN is single-threaded app, so degrade while connect-disconnect rate utilize single core performance. Here is two ways to avoid CAP disconnects: 1. Rise up single core frequency: use 3011 or CHR as single controller. 2. Set up multiple controllers: 2011 can serve 300-400 concurrent connect...

Re: CLOUD CORE ROUTER

Has anyone used the CCR for hotspot deployments? I'm curious about max user counts and CPU load. Have test hotspot installation with 1036 as hotspot and 27 AP (SxT-G2HnD). Work fine, 70-150 online users (more than 4k in radius database) with simple queues. CPU usage less than 1-2%, peak traffic 30M...

Re: This is how is done and everybody should do the same

I often give installers the device with a wire inserted in such a way.
Аdapter can not be lost, but the installer knows how to arrange the wire, so you laughter are not very relevant.

Re: CLOUD CORE ROUTER

While reading forum, i often look complains about poor performance not only in queues and pptp tunnels, but also in general applications such VLANs. Also, according profiler, seems queue process utilize much less CPU...

Re: CLOUD CORE ROUTER

Normis, same situation, as with OlegM. I tried to use ccr1036 as pptp NAS with queues and nat. Seems, when traffic come to around 100Mbps, some cores bring 100% use by IRQs, that may lead to lags and traffic forwarding stop. Else processes in profile look like low CPU consumption.

Wrong RSTP packet flow.

Hi guys. I was faced with incorrect work with RSTP in bridge, which includes vlan interfaces. In this case the vlan interface is the uplink, RSTP packets from the upstream switch come through in a tagged form, but the response mikrotik sends through this interface in untagged form, which leads to th...
