SLB Commands—"i" Series Switches Only

configure slb global tcp-port-check

configure slb global tcp-port-check frequency <seconds> timeout <seconds>
Description
Configures the default health checking frequency and timeout period using layer 4-based TCP port
testing.
Syntax Description
frequency Specifies the frequency of the TCP port check. The range is 5 to 120 seconds.
timeout Specifies the timeout of the TCP port check. The range is 5 to 300 seconds.
Default
The default frequency is 30 seconds.
The default timeout is 90 seconds.
Usage Guidelines
The frequency must be less than the timeout.
The TCP port check is the least intrusive health check, because it does not log in to or access the server.
If the frequency and timeout are not specified for a specific node, the global values are used. You can
configure a node to override the global values using the following command:
configure slb node <ip address> : <L4 port> tcp-port-check
To enable TCP port checking, use the following command:
enable slb node tcp-port-check
Example
The following command sets the global TCP port check frequency to 15 seconds and timeout to
45 seconds:
configure slb global tcp-port-check frequency 15 timeout 45
