 Management Security  RADIUS  Radius Configuration.
The Current Server IP Address field is blank if no servers are configured (see Configure
a RADIUS Server on page 268). The switch supports up to three configured RADIUS
servers. If more than one RADIUS servers 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.
8. In the Max Number of Retransmits field, specify the value of the maximum number of
times a request packet is retransmitted to the RADIUS server
.
The valid range is 1 – 15. The default value is 4.
Give consideration to maximum delay time when configuring RADIUS maximum
retransmits and RADIUS time-outs. 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 retransmit times time-out for all
configured servers. If the RADIUS request was generated by a user login attempt, all
user interfaces are blocked until the RADIUS application returns a response.
9. In the T
imeout Duration field, specify the time-out value, in seconds, for request
retransmissions.
