i?m planning a worst case scenario for a customer site. They got a couple of 6500?s with WiSM Modules installed. Now I?m sitting over a instruction of what to do when a WiSM breaks down and I got a few questions regarding the clients.
In the case a Controller stops responding, the AP?s are automatically switched to the secondary Controllers. What happens when the Primary Controller returns - they automatically switch back, right? Is this automatic switch combined with a loss of wireless connectivity? (LWAPP tunnel gets torn down, and a new LWAPP connection must be established - that is basically the same if I restarted the AP, isn?t it? ) If so, how long does it take for the connectivity to return? Is it possible to manually do the switch to a later time (late in the evening..) to minimize the effects for the clients? The Goal is to keep the clients up and running, without termination of the wireless connection - if this is possible.
