CAPsMAN Wireless clients do not get IP addresses

Sat Aug 26, 2017 1:51 am

I have recently configured a CAPsMAN setup. I've got it going, my CAP is provisioned correctly with both wireless interfaces managed by the CAPsMAN.
But the thing is... whey I try to register with a wireless client, I'm able to, the wireless registration succeeds, but the client does not get an IP address.
So here's the thing, in the log I see:
aug/26 01:38:13 caps,info 48:27:EA:BE:6D:D7@CAP_5GHz connected
aug/26 01:38:20 dhcp,warning dhcp-local offering lease for 48:27:EA:BE:6D:D7 without success
aug/26 01:38:49 caps,info 48:27:EA:BE:6D:D7@CAP_5GHz disconnected, received disassoc: sending station leaving (8)

So the original request from the client is received and the DHCP server responds but apparently the client does not get the DHCP offer and hence it does not respond.
I'm really struggling to find out what's wrong with my config. Here's how it looks like:

Have you guys stumbled upon this?

Re: CAPsMAN Wireless clients do not get IP addresses

So here's how I was able to solve this.
As I saw in several guides and videos, the bridge interface that's associated with the CAPs Manager should have STP disabled. I did the same with the CAP bridge interface.
After doing that I was able to get it working. So I guess it might have been the STP that has been blocking the traffic.
