Displaying the default GSLB policy
Use the show gslb default command to view the default GSLB policy settings for the Brocade Virtual
ADX including the default processing order of the GSLB policy algorithm and the status of many
optional features including the active-only and best-only DNS response parameters.
To display the default GSLB policy, enter the show gslb default command:
Syntax: show gslb default
This display shows the following information.
TABLE 17 GSLB policy information
Field Description
Default algorithm Indicates whether this policy is in effect. The value can be one of the following:
•
Disable
•
Enable
If the state is Disable, then a user-configured policy is in effect instead.
Metric processing order Indicates the order in which the selection metrics are applied to the server
addresses in the DNS reply. For information about the metrics, refer to
“GSLB
policy” on page 6.
DNS active-only Indicates whether the GSLB Brocade Virtual ADX removes IP addresses from the
DNS response if those addresses fail a health check. This field can have one of
the following values:
•
DISABLE: The Brocade Virtual ADX does not remove the IP addresses from
the DNS response.
•
ENABLE: The Brocade Virtual ADX removes IP addresses that fail a health
check from the DNS response.
