RB3011+WAP+CAPsMAN > problems with 2.4GHz - disconnects

Thu May 17, 2018 10:55 am

Hello,

I have a simple setup with the RB3011 mostly in its default configuration. Attached to it is a WAP configured as CAP device.
Added one bridge for guest network, "bridge-guest".
There are configurations for CAPsMAN, one for the 2.4GHz and one for the 5GHz.

I can configure the 5GHz interface to connect to either bridge (defcon "bridge" and "bridge-guest"), that works OK.

However, the 2.4GHz cannot be configured to connect to the default "bridge". If I try this, the RB3011 logs:
"ether6-master: bridge port received packet with own address as source address (....), probably loop". The CAP is disconnected, the wireless networks go offline and after 10s there's a new attempt with the same result.

I did notice the following:

Is it possible that the loop is caused by conflicting addresses between remote-cap and radio-mac for cap6 (being the 2.4GHz)?
Not sure how/what to change to correct this properly. Seems to me like the default configuration should just work out of the box.

Thanks for any pointers!

This was due to the bridge being active inside the WAP, after manually reconfiguring the device to CAPS. When you do a reset of the device into CAPS mode, this bridge is disabled.
Thanks for all the pointers. 8)
