I currently have 7 WLCs with the same Vlan interfaces defined across all 7 controllers. Does anyone know the best practice for addressing these interfaces on each of the WLCs. I currently have each unique Vlan interface assigned with the same IP address across all 7 WLCs. This is working. Should I leave it this way or should I assign each controller with a different address for the Vlan interface?
If I read this correctly you have used the same IP address on all the VLAN interfaces across all the controllers? If so I'm surprised this is working. Each controller should have a unique IP address for every interface. The only interface that should have the same IP address as the other controllers is the virtual interface.
These interfaces are the interfaces that are assigned to the SSIDs. In the manual they are called the Dynamic interfaces. I inherited the network and the addresses were assigned when I got here. It's been working this way for close to a year. The section on the interface config page entitled "Interface Address" with the fields Vlan identifer, IP address,netmask and gateway. Is what I'm talking about.
