ARAMETERS
These parameters are displayed:
Common Server Configuration
◆
Timeout
– The time the switch waits for a reply from an authentication
server before it resends the request. (Range: 3-3600 seconds;
Default: 15 seconds)
◆
Dead Time
– The time after which the switch considers an
authentication server to be dead if it does not reply.
(Range: 0-3600 seconds; Default: 300 seconds)
Setting the Dead Time to a value greater than 0 (zero) will cause the
authentication server to be ignored until the Dead Time has expired.
However, if only one server is enabled, it will never be considered dead.
RADIUS/ Server Configuration
◆
Enabled
– Enables the server specified in this entry.
◆
IP Address/Hostname
– IP address or IP alias of authentication
server.
◆
Port
– Network (UDP) port of authentication server used for
authentication messages. (Range: 1-65535; Default: 0)
If the UDP port is set to 0 (zero), the switch will use 1812 for RADIUS
authentication servers, 1813 for RADIUS accounting servers, or 49 for
authentication servers.
◆
Secret
– Encryption key used to authenticate logon access for the
client. (Maximum length: 29 characters)
To set an empty secret, use two quotes (“”). To use spaces in the
secret, enquote the secret. Quotes in the secret are not allowed.
