[jawad-mukhtar]

Dear Expert,

Want to know.

if we have 6 LW access points Two wlc 2106 and wlc 4402-50k

Can we use both wlc as active and failover with 6 and 50 licenses.

Yes but it'll depend on HOW LONG do you want your failover.

Both the 2106 and the 4400 so which means you go back to a 20-second failover.  Configuration can be done globally or on individual AP.

Both models do not support Stateful Switch Over (SSO) that can only run on 2504, 5508 WiSM-2 and others.

If you configure global or AP-level HA (not to be confused with SSO), then yes.  When your primary controller fails, the AP will site there waiting for the primary controller to recover for about 20 seconds.  Then they will switch to the secondary.  When the primary recovers, you have the option to switch back, the AP will join the primary controller again.

During the "delay" to switch over from primary to secondary (and back), any clients connection will fail.   Full authentication will occur once the AP has settled into thier respective controller.

Hi,

Yes you can use both of them as Active and Failover.
