This is the administrative on/off switch for a configured AAA server entry, showing whether the operator has enabled (up) or disabled (down) the use of that server. Because the value is user-modifiable and independent of whether the server is actually reachable, an administrator can use it to intentionally take a AAA server out of service, for example during maintenance, without deleting its configuration. For example, setting aaaServerAdminStatus to down for a decommissioned RADIUS host stops the device from sending it any more Access-Request messages while keeping its address and shared secret on file for later reuse.
