To specify multiple RADIUS server hosts, configure the radius-server host command multiple times. If
multiple RADIUS server hosts are configured, Dell Networking OS attempts to connect with them in the
order in which they were configured. When Dell Networking OS attempts to authenticate a user, the
software connects with the RADIUS server hosts one at a time, until a RADIUS server host responds with
an accept or reject response.
If you want to change an optional parameter setting for a specific host, use the
radius-server host command.
To change the global communication settings to all RADIUS server hosts, refer to Setting global
communication parameters for all RADIUS server hosts on page 786.
To view the RADIUS configuration, use the
show running-config radius command in the EXEC Privilege
mode.
To delete a RADIUS server host, use the
no radius-server host {hostname | ip-address} command.
Setting global communication parameters for all RADIUS server hosts
You can configure global communication parameters (auth-port, key, retransmit, and timeout parameters)
and specific host communication parameters on the same system. However, if both global and specific host
parameters are configured, the specific host parameters override the global parameters for that RADIUS
server host.
To set global communication parameters for all RADIUS server hosts, use any or all of the following
commands in the CONFIGURATION mode:
To view the configuration of RADIUS communication parameters, use the
show running-config command in
the EXEC Privilege mode.

retransmits RADIUS requests.
• retries range: 0 to 100. Default is 3 retries.
