I am having issues with our access points after a link failure.
So satellite office with primary MPLS and backup VPN link.
If MPLS link fails, all the access points become disconnected from the WLC. However if I reset the AP they will re-join the WLC with no issues over the backup VPN link. What I need is a way that the AP will automatically reconnect using the backup link. There are no IP changes if the link fails, it is just the path that changes.
Using Cisco 3504WLC running 126.96.36.199 and AP AIR-AP2802I-E-K9 running version 188.8.131.52.
Any ideas or advice is greatly appreciated.
Is Your WLC located centrally, and remote office have AP ?
This is more of your Failover setting between the Links, Since AP Look for the IP of WLC. if they find they register automatically.
check your Link failover / IP SLA for the Links ( when the MPLS go down, all should fail over to VPN or what ever alternative Link)
Tried that. I can connect to the remote AP (after link failure via SSH) and ping the WLC no issues.
From the Central WLC I can ping the AP no issues
It is just they do not want to talk to each other any more for authentication
AP shows are trying to connect, tried 6 times then
However if I reset the AP, all works fine and reconnects without any issues.
One way is MPLS connection so no NAT.
Failover runs over VPN but traffic is not NATTED just goes over secure connection (i.e. site to site VPN)
