WLC with RADIUS Authentication Servers

[Irshad Mohammed Hussain]

I have WLC  Users Authentication with Cisco ISE whcih is linked with LDAP , now ISE is not reachable. Will Wireless users were still able to connect and use WLC Services?

Hello Irshad-

All clients that were already authenticated will continue to work and be allowed on the network until they leave the network and/or re-auth, idle, etc type timers expire. At that point clients will not be allowed to join the SSID and will not get access to the network. 

To prevent that from happening you can:

1. Create redundancy by having more than one ISE node

2. Create a secondary authentication method via another RADIUS server or LDAP

I hope this helps!
