Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

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
To allow users to specify a RADIUS server at login, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Allows users to specify a RADIUS server to send
the authentication request when logging in. The
default is disabled.
switch(config)# radius-server
directed-request
Step 2
Exits configuration mode.switch(config)# exit
Step 3
(Optional)
Displays the directed request configuration.
switch# show radius-server
directed-request
Step 4
(Optional)
Copies the running configuration to the startup
configuration.
switch# copy running-config
startup-config
Step 5
Configuring the Global RADIUS Transmission Retry Count and Timeout Interval
You can configure a global retransmission retry count and timeout interval for all RADIUS servers. By default,
a switch retries transmission to a RADIUS server only once before reverting to local authentication. You can
increase this number up to a maximum of five retries per server. The timeout interval determines how long
the Cisco Nexus 5000 Series switch waits for responses from RADIUS servers before declaring a timeout
failure.
To configure the global RADIUS transmission retry count and timeout interval, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies the retransmission count for all RADIUS
servers. The default retransmission count is 1 and the
range is from 0 to 5.
switch(config)# radius-server
retransmit count
Step 2
