3Com 4210 9-Port - Configuring the Status of RADIUS Servers

2-18
z If you change the type of RADIUS server, the data stream destined to the original RADIUS server
will be restored to the default unit.
z When the third party RADIUS server is used, you can select standard or extended as the
server-type in a RADIUS scheme; when the CAMS server is used, you can select extended as the
server-type in a RADIUS scheme.
Configuring the Status of RADIUS Servers
For the primary and secondary servers (authentication/authorization servers, or accounting servers) in
a RADIUS scheme:
When the switch fails to communicate with the primary server due to some server trouble, the switch will
turn to the secondary server and exchange messages with the secondary server.
After the primary server remains in the block state for a set time (set by the timer quiet command), the
switch will try to communicate with the primary server again when it receives a RADIUS request. If it
finds that the primary server has recovered, the switch immediately restores the communication with
the primary server instead of communicating with the secondary server, and at the same time restores
the status of the primary server to active while keeping the status of the secondary server unchanged.
When both the primary and secondary servers are in active or block state, the switch sends messages
only to the primary server.
