Do you have to deal with re-authentication when your wireless internet connection drops? Isn’t it annoying when you have to deal with minutes seconds of failover?

You may be suffering from downtime resulting from your primary controller going down.

Symptoms include: network downtime, poor quality of experience for users, and major headache for IT. This is because when the controller goes down, the access point has to rebuild the CAPWAP tunnel completely from scratch, rebuild all channel and power settings on the Access Points, resulting in the users having to reauthenticate and lose all data from the previous connection. This can be annoying for users, which in turn puts pressure on IT.

Luckily for you, Cisco has Stateful SwitchOver for Wireless!

Cisco Stateful SwitchOver solves all the problems of controller fail-over downtime with its innovative setup of a secondary stand-by controller that holds a replica copy of all the data being exchanged between the access point and the controller. This means that when the primary controller fails, there is a sub-second (yes, less than one-second) switchover for hundreds of Access Points to the secondary controller AND a seamless user experience! Sound too good to be true? It’s not.

Check out this short 2 minute video on the basics of SSO:
