I have 3 C5x clients and an A5c setup with 1 VLAN for Management. All radios have the 2.5.3 firmware and I have 1 SSID setup as a Trunk (a.k.a. pass through). As far as I can tell the STP BPDUs make it from the A5c to the C5x’s but not back the other way.
I have a mix of Cisco 3000 and 3300 switches. I am trying to use 2 VLANs for data.
So far tech support has told be to try about 4 different versions of firmware(including betas), but none have resolved the issue.
