Defining a name for a host-level GSLB policy

To define a name for a host-level GSLB policy, enter commands such as the following:

GSLB ServerIronADX# config t

GSLB ServerIronADX(config)# gslb-host-policy abc

GSLB ServerIronADX(config-gslb-host-policy-abc)#

The commands create a host-level GSLB policy named abc.

Syntax: [no] gslb-host-policy <policy name>

Configuring the parameters for the host-level policy

Enabling the active bindings metric

To enable the active bindings metric for a host-level GSLB policy, enter commands such as the following:

GSLB ServerIronADX(config)# gslb-host-policy abc

GSLB ServerIronADX(config-gslb-host-policy-abc)# active-bindings

Syntax: [no] active-bindings

Enabling the Capacity Threshold metric

You can enable the capacity threshold metric for a host-level GSLB policy. This metric represents a site ServerIron ADX’s available TCP/UDP session capacity. This metric is enabled by default, which means the GSLB ServerIron ADX uses this metric when evaluating the sites in a DNS reply to choose the best site.

To enable the capacity threshold metric, enter commands such as the following:

GSLB ServerIronADX(config)# gslb-host-policy abc

GSLB ServerIronADX(config-gslb-host-policy-abc)# capacity

Syntax: [no] capacity

Use the no form of the command to disable the Capacity Threshold metric.

NOTE

To configure a Capacity Threshold value, do so at the global GSLB policy level. The GSLB ServerIron ADX will apply this value to the host-level GSLB policy.

Enabling the connection load metric

To enable the Connection Load metric for a host-level GSLB policy, enter commands such as the following:

GSLB ServerIronADX(config)# gslb-host-policy abc

GSLB ServerIronADX(config-gslb-host-policy-abc)# connection-load limit 4

Syntax: [no] connection-load limit <value>

Use the no form of the command to disable the Connection Load metric.
