This read-create Integer32 (0-64) controls how many times the device retries a query to this AAA server before failing over to the next server in the associated server list, though it cannot be changed for LDAP servers since those follow TCP's own retry schedule (12 tries, doubling from 1.5 seconds up to a 64-second cap). An admin tunes this for RADIUS servers to balance fast failover against tolerance for brief server hiccups. For example, setting this to 2 on a RADIUS entry means the device gives up on that server after two retries and moves to the backup server sooner during an outage.
