Cisco 1310 bridges and FreeRadius authentication

Hi all,

I have two 1310 bridges...one configured as root and the other as non-root.

Authentication Settings: Open with EAP and Network EAP with no addition.

Set up: when non-root bridge tries to associate with root bridge, root bridge checks with radius server if it's ok to associate with the non-root bridge

I can see communication with the radius server (I'm using FreeRadius) and the radius server even sends a SUCCESS back to the root bridge.

However I'm seeing this error on the non-root bridge: %DOT1X_SHIM-3-PLUMB_KEY_ERR: Unable to plumb keys - Eap key struct is NULL and the bridges do not authenticate.

Any ideas how I can solve this issue?

Many thanks

Charmaine

Hello again,

I have attached the configuration files of the root and non-root bridge.

Thanks
