Host-level policies for site selection
1. Define a name for the host-level GSLB policy. Refer to page 118.
2. Configure the parameters for the policy. Refer to page 118.
3. Apply the policy to a host or multiple hosts. Refer to page 125.
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.
