Chapter 1 Configuring TACACS+
Configuring TACACS+
The following example shows how to configure periodic TACACS+ server monitoring:
switch# configure terminal
switch(config)# tacacs-server host 10.10.1.1 test username user1 password Ur2Gd2BH
idle-time 3
switch(config)# tacacs-server dead-time 5
switch(config)# exit
switch# show tacacs-server
switch# copy running-config startup-config
Configuring the Dead-Time Interval
You can configure the dead-time interval for all TACACS+ servers. The dead-time interval specifies the
time that the Nexus 5000 Series switch waits, after declaring a TACACS+ server is dead, before sending
out a test packet to determine if the server is now alive.
Note When the dead-timer interval is 0 minutes, TACACS+ servers are not marked as dead even if they are
not responding. You can configure the dead-timer per group (see the “Configuring TACACS+ Server
Groups” section on page 1-8).
To configure the dead-time interval for all TACACS+ servers, perform this task:
Command Purpose
Step 1
switch# configure terminal
Enters configuration mode.
Step 2
switch(config)# tacacs-server host
{ipv4-address | ipv6-address | host-name}
test {idle-time minutes | password
password [idle-time minutes] | username
name [password password [idle-time
minutes]]}
Specifies parameters for server monitoring. The
default username is test and the default password is
test. The default value for the idle timer is 0 minutes
and the valid range is 0 to 1440 minutes.
Note For periodic TACACS+ server monitoring,
the idle timer value must be greater than 0.
Step 3
switch(config)# tacacs-server dead-time
minutes
Specifies the number minutes before the Nexus
5000 Series switch checks a TACACS+ server that
was previously unresponsive. The default value is 0
minutes and the valid range is 0 to 1440 minutes.
Step 4
switch(config)# exit
Exits configuration mode.
Step 5
switch# show tacacs-server
(Optional) Displays the TACACS+ server
configuration.
Step 6
switch# copy running-config startup-config
(Optional) Copies the running configuration to the
startup configuration.
