of transmission attempts exceeds the specified retry-times, the NAS considers the

priority level, and FTP directory, take effect only after service-type is configured as
3com.
Setting RADIUS Server
State
For primary and secondary servers (no matter they are
authentication/authorization servers or accounting servers) in a RADIUS scheme, if
the primary server is disconnected from the NAS due to some fault, the NAS
automatically turns to the secondary server. However, after the primary one
recovers, the NAS does not resume the communication with it at once; instead,
the NAS continues communicating with the secondary one and turns to the
primary one again only after the secondary one fails. To have the NAS
communicate with the primary server right after its recovery, you can manually set
the primary server state to active.
When both primary and secondary servers are active or blocked, the NAS sends
packets to the primary one only.
Perform the following configurations in RADIUS view.
