Chapter 17 Configuring RADIUS
Configuring RADIUS Servers
The following example shows how to configure a RADIUS server group:
switch# configure terminal
switch(config)# aaa group server radius RadServer
switch(config-radius)# server 10.10.1.1
switch(config-radius)# deadtime 30
switch(config-radius)# use-vrf management
switch(config-radius)# exit
switch(config)# show radius-server group
switch(config)# copy running-config startup-config
Allowing Users to Specify a RADIUS Server at Login
Note By default, the Nexus 5000 Series switch forwards an authentication request based on the default AAA
authentication method. You can configure the Nexus 5000 Series switch to allow the user to specify a
VRF and RADIUS server to send the authenticate request by enabling the directed-request option. If you
enable this option, the user can log in as username@hostname, where hostname is the name of a
configured RADIUS server. User specified logins are only supported for Telnet sessions.
To allow users to specify a RADIUS server at login, perform this task:
Step 3
switch(config-radius)# server
{ipv4-address |ipv6-address |
server-name}
Configures the RADIUS server as a member of the
RADIUS server group.
Tip If the specified RADIUS server is not found,
configure it using the radius-server host
command and retry this command.
Step 4
switch(config-radius)# deadtime minutes
(Optional) Configures the monitoring dead time. The
default is 0 minutes. The range is from 1 through 1440.
Note If the dead-time interval for a RADIUS server
group is greater than zero (0), that value takes
precedence over the global dead-time value.
See the example that shows how to configure
periodic RADIUS server monitoring.
Step 5
switch(config-radius)# exit
Exits configuration mode.
Step 6
switch(config) #show radius-server group
[GROUP-NAME]
(Optional) Displays the RADIUS server group
configuration.
Step 7
switch(config)# copy running-config
startup-config
(Optional) Copies the running configuration to the
startup configuration.
