The configuration required for the GSLB distributed health check feature depends on whether the GSLB ServerIron ADX and the site ServerIron ADX support the distributed health check feature or not. Refer to the table below for more information on the configuration available and mandated by the GSLB distributed health check feature.

No configuration required. Flashback metric enabled by default.

•Neither GSLB ServerIron ADX nor site ServerIron ADX is running the 08.1.00S release. Refer to the relevant release notes for information.

Disabling the distributed health check feature for an individual site ServerIron ADX

If a site ServerIron ADX does not support the distributed health check feature, and if the GSLB ServerIron ADX supports the distributed health check feature, then distributed health check feature should be disabled for that site ServerIron ADX as it does not support distributed health checking i.e. the GSLB ServerIron ADX still needs to maintain health checks for the host servers being load balanced by that site ServerIron ADX.

To disable distributed health check feature for an individual site ServerIron ADX, enter commands such as the following on the GSLB ServerIron ADX, not on the site ServerIron ADX.

GSLB-ServerIronADX(config)# gslb site sunnyvale GSLB-ServerIronADX(config-gslb-site-sunnyvale)# si-name 1.1.1.107 no-si-dist-health-check

Syntax: [no] si-name [<name>] <ip-addr>no-si-dist-health-check

NOTE

The si-namecommand also has an optional parameter that specifies the ServerIron ADX’s preference. This parameter is not related to the distributed health check feature.
