I'm having a strange problem, and I'm having trouble figuring it out.
I'm running two 4402 controllers connect via dot1q trunks to a 6509 (Native VLAN 1).
I have been creating VLAN interfaces on the controllers and assigning them to WLANs...everything seems to be working fine except when I try to add my VLAN 10.
VLAN 10 is addressed 10.18.0.0/16.
All my WAPs and Controllers are on VLAN 2 (10.12.0.0/16)
My WCS is on VLAN 10 (10.18.1.x).
When I add a VLAN 10 interface of (10.18.201.x) on my controller, I am unable to reach the controller by the Management IP address on VLAN2. This happens with both of my controllers. It appears to be intermittent... For one minute I can ping the management interface and not the VLAN 10 Interface I created...and vice versa.
WCS reports the controllers and being down, and I'm unable to push policy to them.
Please help me with this matter, it's driving me crazy.
Thank you in advance,
