Host-level policies for site selection

ServerIron ADX provides the following support for configuring GSLB policies for specified GSLB hosts:

•Configuring GSLB policies and apply them to hosts within GSLB domains

•Applying the global GSLB policy to all hosts

•Applying a host-level GSLB policy to one or more hosts

•Applying the global GSLB policy to some hosts and host-level GSLB policies to other hosts

Global vs host-level policy

The parameters for a host-level GSLB policy are similar to the parameters for the global GSLB policy. However, not all global GSLB parameters are available at the host level.

You can configure the following GSLB parameters under the global GSLB policy only:

•Geographic prefix (geo-prefixcommand) (see “Geographic region for a prefix” on page 129)

•Static prefix (static-prefixcommand)

•Health-status reporting interval (health-status-intervalcommand)

•GSLB protocol update interval (protocol status-intervalcommand)

Configuring host-level policies

Host-level GSLB policies provide finer granularity in specifying the GSLB metrics, related parameters, and the metric order, by applying them at the host level.

To configure a host-level GSLB policy, complete the following tasks.
