Chapter 18 Configuring
Configuring
To configure server groups, perform this task:
The following example shows how to configure a server group:
switch# configure terminal
switch(config)# aaa group server TacServer
switch(config-)# server 10.10.2.2
switch(config-)# deadtime 30
switch(config-)# exit
switch(config)# show tacacs-server groups
switch(config)# copy running-config startup-config
Specifying a Server at Login
You can configure the switch to allow the user to specify which server to send the authenticate
request by enabling the directed-request option. By default, a Nexus 5000 Series switch forwards an
authentication request based on the default AAA authentication method. If you enable this option, the
user can log in as
username @ hostname, where hostname is the name of a configured RADIUS server.
Note User specified logins are only supported for Telnet sessions.
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# aaa group server
group-name
Creates a server group and enters the
server group configuration mode for that
group.
Step 3
switch(config-)# server
{ ipv4-address | ipv6-address | host-name }
Configures the server as a member of the
server group.
Tip
If the specified server is not found,
configure it using the
tacacs-server host
command and retry this command.
Step 4
switch(config-)# deadtime minutes
(Optional) Configures the monitoring dead time. The
default is 0 minutes. The range is from 0 through 1440.
Note If the dead-time interval for a
server group is greater than zero (0), that value
takes precedence over the global dead-time
value.
Step 5
switch(config-)# exit
Exits configuration mode.
Step 6
switch(config)# show tacacs-server
groups
(Optional) Displays the server group
configuration.
Step 7
switch(config)# copy running-config
startup-config
(Optional) Copies the running configuration to the
startup configuration.
