Chapter 1 Configuring TACACS+
Configuring TACACS+
The following example shows how to configure the TACACS+ 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 TACACS+ 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 TACACS+ 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 1-3.
To configure TACACS+ server groups, perform this task:
Step 3
switch(config)# exit
Exits configuration mode.
Step 4
switch# show tacacs-server
(Optional) Displays the TACACS+ server
configuration.
Note The preshared keys are saved in encrypted
form in the running configuration. Use the
show running-config command to display the
encrypted preshared keys.
Step 5
switch# copy running-config
startup-config
(Optional) Copies the running configuration to the
startup configuration.
Command Purpose
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# aaa group server tacacs+
group-name
Creates a TACACS+ server group and enters the
TACACS+ server group configuration mode for that
group.
Step 3
switch(config-tacacs+)# server
{ipv4-address|ipv6-address|host-name}
Configures the TACACS+ server as a member of the
TACACS+ server group.
Tip If the specified TACACS+ server is not found,
configure it using the tacacs-server host
command and retry this command.
Step 4
switch(config-tacacs+)# 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 TACACS+
server group is greater than zero (0), that value
takes precedence over the global dead-time
value.
