About global versus per-RADIUS server passkeys (shared secrets)

To communicate with a RADIUS AAA server, the switch must have a passkey (shared secret) configured that matches what is configured on the server. Use one of these commands to achieve the desired configuration:
  • For a global passkey common to every RADIUS server, use radius-server key.

  • For a per-RADIUS server passkey, use radius-server host with the key parameter.


If both passkeys are configured on the switch, the per-RADIUS server passkey is used.
