Configuring Server Load Balancing

Modifying Optional Parameters

As shown in the table on
for the SLB cluster's distribution algorithm, "sticky" time, ping timeout, ping period, and ping retries. The
following subsections describe how to modify these parameters.
•
Modifying the Ping Period. You can modify the ping period with the
command, which is described in
•
Modifying the Ping Timeout. You can modify the ping timeout with the
command, which is described in
•
Modifying the Number of Ping Retries. You can modify the number of ping retries with the
cluster ping retries

Modifying the Ping Period

The default ping period (i.e., the time interval at which the health of servers is checked) is 60 seconds.
You can modify this value from 0 (this will disable the ping) to 3600 seconds with the
period command by entering ip slb cluster, the name of the SLB cluster, ping period, and the user-speci-
fied number of seconds.
For example, to set the ping period on an SLB cluster called "Web_Server" to 1200 seconds enter:
-> ip slb cluster Web_Server ping period 120
Note. If you set the ping period to any value other than 0, then the ping period must be greater than or
equal to the ping timeout value divided by 1000. For example, if the ping timeout is 5000 milliseconds,
the ping period must be at least 5 seconds. The ping timeout value can be modified with the
ping timeout command, which is described in

Modifying the Ping Timeout

The default ping timeout is 3000 milliseconds. You can modify this value from 0 to 1000 times the value
of the ping period with the
the SLB cluster, ping timeout, and the user-specified number of milliseconds.
For example to set the ping timeout on an SLB cluster called "Web_Server" to 1000 milliseconds enter:
-> ip slb cluster Web_Server ping timeout 1000
Note. You can modify the ping period with the
