You can configure up to three RADIUS servers per SBC. When more than one RADIUS server is configured and RADIUS authentication is attempted, the server configured with the least priority value is tried first. If fallback is configured, the inverse priority order is followed to pick the next server for authentication. SBC allows a configurable number of retries and time-outs before retry.
