DCS-3950 series Ethernet switch manual
Command: radius-server authentication host <ip-address > [port <port-number>]
[primary]
no radius-server authentication host ip-address >
Function: Specify the IP address and listening port number for the RADIUS server; the
‘no radius-server authentication host <IPaddress>‘ command deletes the RADIUS
authentication server
Parameters: <ip-address > stands for the server IP address; <port-number> for
listening port number, from 0 to 65535, where 0 stands for non-authentication server
usage; primary for primary server.
Command mode: Global Mode
Default: No RADIUS authentication server is configured by default.
Default: No RADIUS authentication server is configured by default.
Usage Guide: This command is used to specify the IP address and port number of the
specified RADIUS server for switch authentication, multiple command instances can be
configured. The port parameter is used to specify authentication port number, which
must be the same as the specified authentication port in the RADIUS server, the default
port number is 1812. If this port number is set to 0, the specified server is regard as
non-authenticating. This command can be used repeatedly to configure multiple RADIUS
servers communicating with the switch, the configured order is used as the priority for the
switch authentication server. If primary is specified, then the specified RADIUS server
will be the primary server.
Example: Set the RADIUS authentication server address as 200.1.1.1.
Switch(Config)#radius-server authentication host 200.1.1.1
14.2.2.25 radius-server dead-time
Command: radius-server dead-time <minutes>
no radius-server dead-time
Function: Configure the restore time when RADIUS server is down; the ‘no
radius-server dead-time’ command restores the default setting.
Parameters: < minute > is the down -restore time for RADIUS server in minutes, the valid
range is 1 to 255.
Command mode: Global Mode
Default: The default value is 5 minutes.
Usage Guide: This command specifies the time to wait for the RADIUS server to recover
from inaccessible to accessible. When the switch acknowledges a server to be
inaccessible, it marks that server as having invalid status, after the interval specified by
this command; the system resets the status for that server to valid.
Example: Set the down-restore time for RADIUS server to 3 minutes.
Switch(Config)#radius-server dead-time 3
14.2.2.26 radius-server key
Command: radius-server key <string>
