Step 4
(Optional)

Step 6
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

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 Cisco 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.
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.
Note
To configure the dead-time interval for all TACACS+ servers, perform this task:
Procedure
