Host-level policies for site selection
1
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-Virtual ADX#config t
GSLB-Virtual ADX(config)#gslb-host-policy abc
GSLB-Virtual ADX(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-Virtual ADX(config)#gslb-host-policy abc
GSLB-Virtual ADX(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 ADX device’s available TCP/UDP session capacity. This metric is enabled by default, which
means the GSLB Brocade Virtual 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-Virtual ADX(config)#gslb-host-policy abc
GSLB-Virtual ADX(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 Brocade
Virtual 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-Virtual ADX(config)#gslb-host-policy abc
GSLB-Virtual ADX(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.
You must specify a connection limit to enable the Connection Load metric. You can specify a value
from 1 to as high a value as you need. There is no default. However, the actual value of the
Connection Load limit, and other connection load parameters, will be obtained from the global
GSLB policy.
Other connection load parameters include the following:
