I have a strange thing going on on our network here with our UC520 and WLC526. I have the WLC and 2 AP521s connected directly to the PoE ports on the UC520. The WLC is setup for 3 VLANs with the associated VLANs and networks - data (VLAN 1, 10.0.96.0), voice (VLAN 100, 10.1.1.0), and guest (VLAN 50, 10.0.97.1). I have ACLs setup on the WLC526 that should prevent 10.0.97.0 from reaching 10.0.96.0. The SSIDs for data and guest are both broadcast, but different (Nomad GCS, and Nomad GCS guest). For some reason, whenever you bring a computer up on the guest WLAN, it automatically gets a 10.0.96.0 address. If you perform an ipconfig/release and renew a couple of times, you'll eventually get an address in the 10.0.97.0 range, but it doesn't happen automatically.
I am only using 1 port of the WLC and the smartports are set to VLAN 1. The second port is not connected to anything.
All laptops that we have been testing with have already been connected to the data VLAN and their MAC addresses have been added to the MAC address list.
Has anybody else seen anything like this?
Thanks in advance,
