Configuring RADIUS Server Hosts
You must configure the IPv4 or IPv6 address or the host name for each RADIUS server that you want to use
for authentication. All RADIUS server hosts are added to the default RADIUS server group. You can configure
up to 64 RADIUS servers.
To configure a RADIUS server host, perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies the IPv4 or IPv6 address or hostname
for a RADIUS server.
switch(config) #radius-server host
{ipv4-address | ipv6-address | host-name}
Step 2
Exits configuration mode.switch(config)# exit
Step 3
(Optional)
Displays the RADIUS server configuration.
switch# show radius-server
Step 4
(Optional)
Copies the running configuration to the startup
configuration.
switch# copy running-config
startup-config
Step 5
The following example shows how to configure a RADIUS server host:
switch# configure terminal
switch(config)# radius-server host 10.10.1.1
switch(config)# exit
switch# show radius-server
switch# copy running-config startup-config
Configuring RADIUS Global Preshared Keys
You can configure preshared keys at the global level for all servers used by the Cisco Nexus 5000 Series
switch. A preshared key is a shared secret text string between the switch and the RADIUS server hosts.
To configure global preshared keys, obtain the preshared key values for the remote RADIUS servers and
perform this task:
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configure terminal
Step 1
Specifies a preshared key for all RADIUS servers. You can
specify a clear text ( 0 ) or encrypted ( 7 ) preshared key.
switch(config)# radius-server
key [0 | 7] key-value
Step 2
The default format is clear text. The maximum length is 63
characters.
By default, no preshared key is configured.
Exits configuration mode.switch(config)# exit
