Wireless anchor issues

[salamislimy]

My Current scenario is Wireless controller > Anchor Controller > Radius

we are in the process of changing the RADIUS server

In current setup traffic flows as WC>Anchor>RADIUS

But when I change the IP of RADIUS to new RADIUS server, it goes WC>RADIUS, doesnt talk to the anchor.

What am I missing? I have a mobility tunnel to the anchors and the mobility anchors are configured on the SSID

New RADIUS servers are configured on the SSID under AAA servers as well.

@salamislimy 

Where are you changing the Radius IP address, on the foreign or on the anchor wlc?

Does the anchor have connectivity with the new radius?

[salamislimy]

Ive changed the RADIUS IP on both the local and the anchor controller.

There is a route to the whole 192.168.20.x range and the new RADIUS IP is just the next IP in the subnet

[Flavio Miranda]

From the anchor, use the following command to test connectivity 

test aaa radius username admin password cisco123 wlan-id 1 apgroup default-group server-index 2

Just chance the parameters accordingly

Ensure the mobility tunnels are up

ensure the radius config matches between the foregn and anchor wlcs

ensure routing and firewall rules allow the RADIUS traffic from Anchor to RADIUS
