Chapter 18 Configuring
Configuring
The following example shows how to configure global preshared keys:
switch#
configure terminal
switch(config)#
tacacs-server key 0 QsEfThUkO
switch(config)#
exit
switch#
show tacacs-server
switch#
copy running-config startup-config
Configuring Server Preshared Keys
You can configure preshared keys for a server. A preshared key is a shared secret text string
between the Nexus 5000 Series switch and the server host.
To configure the preshared keys, perform this task:
The following example shows how to configure the preshared keys:
switch#
configure terminal
switch(config)#
tacacs-server host 10.10.1.1 key 0 PlIjUhYg
switch(config)#
exit
switch#
show tacacs-server
switch#
copy running-config startup-config
Configuring Server Groups
You can specify one or more remote AAA servers to authenticate users using server groups. All members
of a group must belong to the protocol. The servers are tried in the same order in which you
configure them.
You can configure these server groups at any time but they only take effect when you apply them to an
AAA service. For information on AAA services, see the
“Remote AAA Services” section on page 16-2
.
