I am having trouble with a newly configured install. Basically it seems that my centrally switched guest SSID is not functioning. As you change AP groups, which should change the interface associated with the SSID and also the dhcp client address, the client is retaining the original dhcp address from whichever AP group they first associated with.
I also have a locally switch WPA2 SSID at each location which is working fine. Clients are able to change dhcp address correctly as they move between AP groups. It just doesn't seem to be working on the guest network, which is odd because it was working earlier in the install. It has only started having issues yesteday afternoon.
It does not always coincide with the guest errors but I am generating these logging errors:
*DHCP Socket Task: Aug 17 15:09:23.526: %SIM-3-DHCP_SERVER_NO_REPLY: sim_interface.c:1039 Failed to get DHCP response on interface 'may89-guest_vb_122'. Marking interface dirty.
The interface above is assigned to the guest SSID in one of the AP group. I assume this has something to do with it but I've been over my DHCP assignments on the core switch, local switch, controller, and dhcp server and can find no issue with the configuration.....Also the fact that it was working earlier this week.
I also seem to be generating a high amount of:
*dot1xMsgTask: Aug 17 14:46:22.844: %DOT1X-3-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:456 Max EAPOL-key M1 retransmissions exceeded for client xx:xx:xx:xx:xx:xx
I am not sure why as I am not using DOT1X at all. The guest is a pass-thru and the WPA2 network is just WPA + WPA2 with TKIP and AES. No DOT1X anywhere on the controller...
