WLC Interfaces Backup Port

On a WLC 5508 it lists an option to specify a "Backup Port" under the physical information section on an interface. We have two central switched SSID's which are connected to an internal firewall. We are looking at installing a backup/standy firewall and running a virtual firewall between them. Each SSID would have an additional patch from the WLC to the standby firewall.

Does the backup interface port function on the WLC allow traffic to be failed over from a centrally switched SSID via backup interfaces to an alternative device?

If this does work will only physical link failure to the primary firewall cause the backup port to be activiated or is there configuration parameters which can be specified for load, packet loss or latency which can be used as criteria to cause the backup port to be utilised?

Re: WLC Interfaces Backup Port

The backup port only takes over when the primary port state is down. So you can connect the backup to whatever you want, just as long as the interface can still hit the default gateway.
