I'm haivng problems with a UC520 system with a WLC526 and 2x AP521s. The data and voice VLANs are working perfectly and the guest VLAN was (at one time) working properly also. At this point, however, the UC520 is not assigning an IP address to any device on the Guest VLAN.
Guest VLAN UC520 IP: 10.0.97.1
DHCP server: 10.0.97.1
I can ping the guest VLAN IP from the data VLAN 10.0.96.x. When I set a static IP on a guest device and try to ping the guest VLAN IP or Guest DNS, the requests time out.
WLC has been set for no security, no web auth. Currently, I turned web auth back on and created a user account for testing purposes. Any recommendations or things I could check?
FWIW, we have a TAC case that is open, but the TAC tech doesn't know the UC520 - only WAPs and WLCs. He's convinced that it isn't a wireless issue, but rather is a problem with the UC500 not acting as a DHCP server on that VLAN. Everything looks great in CCA, but something is getting missed somewhere.
