[c-nsp] Wireless Controllers, SVIs and WCCP

[Andrew Jones]

New HA configuration for WLC v7 is good, gives you active / standby controllers, so no need for AP to re-associate to alternate controller. Im told its 1-2 sec failover between controller.

Also, you don't need to double up on licensing for your AP, ie 500 ap license plus a HA license is all that is required for 2 controller and 500 ap.

4500 has vss on the roadmap, not sure how far away. For MPLS, your best bet is 6500. Or if you want nexus, try the 7004.

We already have the WLC 5508s with licenses so I won't be able to swap them. I will check out the hotstandby mode though - wasn't aware of it.

The main problem I have with the 4500s is redundantly connecting the WLCs.
The WLCs only support one LACP (LAG) and there is no VSS support on the 4500s. In addition, it may later be decided to turn the "wireless connection" into a collapsed PE/CE - so MPLS support would be a bonus.
