[Solved] CAPsMANv2 and VLANs

RouterOS General
1

Can someone give me a quick primer on what is required to enable multiple SSIDs and VLAN tags using CAPsMANv2?

I want to use local forwarding on all CAPs (I believe this is where the CAP actually tags and forwards the traffic to the switch, as opposed to sending all traffic to CAPsMAN for forwarding).

I’m trying to figure out where I need to create the configuration to make this happen automatically. Do I need to create the necessary VLAN tags on each CAP? Is there any way CAPsMAN can auto-create the necessary VLAN and bridge interfaces on the CAP, or does all traffic HAVE to come through the CAPsMAN when using VLAN tagging?

Any help would be appreciated.

So I’ve made some headway with this, however I seem to have created another problem at the same time.

Since CAPsMAN doesn’t seem to create any interfaces automatically, I created a bridge on the CAP, tagged the needed VLANs and then in Wireless>CAP, told it to add interfaces to this bridge.

The problem I’m having now is my ethernet link is flapping any time I enable a wireless interface in CAPsMAN, resulting in terrible packet loss. Other than that, the tagging is working as expected.

What am I missing here? I’m using a RB912UAG-2HPnD with a secondary R11e-2HPnD card installed. It doesn’t seem to support vlans in switching, so I’m stuck with software VLANs.

So I’ve determined this has to be some type of bug. If I enable the integrated wireless interface on my RB912, the ethernet link flaps utilizing the above bridged configuration. If I disable the integrated wireless interface, it works fine.

Enabling just the pci-e wireless card does not cause problems and the configuration works EXACTLY as I would expect.

This is with 6.28.

This turned out to be an antenna placement issue. As soon as the transmitter was active, it overpowered a nearby capacitor on the board itself which caused the ethernet link to drop.

This is a special use case with the RB912 installed in an RF Elements InSPOT case. Probably not as likely to happen to others out in the field using other products.
