Enabling the distributed health check feature for an individual site ServerIron ADX
You can enable the distributed health check feature for an individual site ServerIron ADX. Enter the
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 abc 1.1.1.107
enable-si-dist-health-check
Syntax: [no] si-name [<name>] <ip-addr> enable-si-dist-health-check
Disabling or re-enabling distributed health check
You can disable the distributed health check feature for an entire GSLB site. When you do this, it
applies to all the site ServerIron ADXs at that site. Note that if there is a configuration to enable or
disable the distributed health check feature on an individual site ServerIron ADX (Refer to
“Disabling the distributed health check feature for an individual site ServerIron ADX” on page 105
and “Enabling the distributed health check feature for an individual site ServerIron ADX” on
page 106), the configuration on the individual ServerIron ADX takes effect for that site ServerIron
ADX and overrides the site configuration for that site ServerIron ADX
To disable distributed health checks for a site, enter commands such as the following, enter the
commands on the GSLB ServerIron ADX, not on the site ServerIron ADX:
GSLB-ServerIronADX(config)# gslb site sunnyvale
GSLB-ServerIronADX(config-gslb-site-sunnyvale)# no-distributed-health-check
Syntax: [no] no-distributed-health-check
To re-enable distributed health checks for the site, enter the following command.
GSLB-ServerIronADX(config-gslb-site-sunnyvale)# no no-distributed-health-check
Clearing the distributed health check settings for a site ServerIron ADX
You can clear the distributed health check settings for a site ServerIron ADX. When you clear the
settings, the site ServerIron ADX inherits the settings configured for the site itself. (Refer to
“Disabling or re-enabling distributed health check” on page 106.) If you have not configured
distributed health check settings for the site, then the distributed health check feature is enabled
for the site ServerIron ADX. This is the default setting for the feature.
To clear the distributed health check settings from a 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
clear-si-health-check-mech
Syntax: [no] si-name [<name>] <ip-addr>clear-si-health-check-mech
Configuring the health status reporting interval
If the GSLB ServerIron ADX supports the distributed health check feature, then you can globally
configure the interval at which the distributed health check site ServerIron ADXs report the health
check information to the GSLB ServerIron ADX for the GSLB distributed health check feature. Note
that if health status interval is configured globally, it applies to all peer site ServerIron ADXs that
support the distributed health check feature.
