The following screen displays:
The Current Server IP Address field is blank if no servers are configured (see
Server Configuration on page 162). The switch supports up to three configured RADIUS
servers. If more than one RADIUS server is configured, the current server is the server
configured as the primary server. If no servers are configured as the primary server, the
current server is the most recently added RADIUS server.
2. In the Max Number of Retransmits field, specify the maximum number of times a request
packet is retransmitted to the RADIUS server. The valid range is 1-15 and the default is 3.
3. In the Timeout Duration field, specify the time-out value, in seconds, for request
retransmissions. The valid range is 1-30 seconds and the default is 3 seconds.
Consideration to maximum delay time must be given when configuring RADIUS
maximum retransmit and RADIUS time-out values. If multiple RADIUS servers are
configured, the maximum retransmit value on each is exhausted before the next server is
attempted. A retransmit does not occur until the configured time-out value on that server
has passed without a response from the RADIUS server. Therefore, the maximum delay
in receiving a response from the RADIUS application equals the sum of (retransmit *
time-out) for all configured servers. If the RADIUS request is generated by a user login
attempt, all user interfaces are blocked until the RADIUS application returns a response.
4. From the Accounting Mode list, select whether the RADIUS accounting mode is enabled or
disabled on the current server.
5. Click APPLY.
Configuration changes take effect immediately.
