Example 1
In this example:
• The GSLB ServerIron ADX supports the distributed health check feature.
• Site ServerIron ADXs 1.1.1.105, 1.1.1.106 and ServerIron ADX 1.1.1.107 all belong to site
“sunnyvale” and do not support the distributed health check feature.
• Site ServerIron ADX 1.1.1.108 belongs to site "santaclara" and supports the distributed health
check feature.
Mandatory configuration is required to disable distributed health check for all ServerIron ADXs at
site “sunnyvale” since none of the ServerIron ADXs at that site support the distributed health check
feature.
Configure the following on the GSLB ServerIron ADX for site “sunnyvale”.
GSLB-ServerIronADX#conf t

GSLB-ServerIronADX(config)#gslb site sunnyvale

GSLB-ServerIronADX(config-gslb-site-sunnyvale)#no-distributed-health-check

GSLB-ServerIronADX(config-gslb-site-sunnyvale)#end
NOTE
You can also achieve the same result by individually disabling distributed health check for each
ServerIron ADX at this site i.e. by disabling distributed health check individually for ServerIron ADX
1.1.1.105, ServerIron ADX 1.1.1.106 and ServerIron ADX 1.1.1.107, but it is simpler and more
concise to just disable it for the whole site.
No mandatory configuration required for ServerIron ADX 1.1.1.108 as it supports the distributed
health check feature.
