Extreme Networks ExtremeWare - Configure Slb Global Tcp-Port-Check

472 ExtremeWare Software 7.3.0 Command Reference Guide
SLB Commands
configure slb global tcp-port-check
configure slb global tcp-port-check frequency <seconds> timeout <seconds>
Description
Configures default health checking frequency and timeout period using layer 4-based TCP port testing.
Syntax Description
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, as it does not log into 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
