Configuring Periodic Server Monitoring
You can monitor the availability of servers. These parameters include the username and
password to use for the server and an idle timer. The idle timer specifies the interval in which a
server receives no requests before the Nexus 5000 Series switch sends out a test packet.You
can configure this option to test servers periodically, or you can run a one-time only test.
Note To protect network security, we recommend that you use a user name that is not the same as an existing
username in the database.
The test idle timer specifies the interval in which a server receives no requests before the
Nexus 5000 Series switch sends out a test packet.
Note
The default idle timer value is 0 minutes. When the idle time interval is 0 minutes, periodic
server monitoring is not performed.
To configure periodic server monitoring, perform this task:
The following example shows how to configure periodic 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
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 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 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 server
configuration.
Step 6
switch# copy running-config startup-config
(Optional) Copies the running configuration to the
startup configuration.
