Displaying GSLB for IPv6 configurations

2

Direct response      =          0 Query type ANY       =          0

Query type A         =         56 Query type AAAA      = 87

The command returns information about the number of requests for three query types: queries for 
IPv4 addresses (A records), queries for IPv6 addresses (AAAA records), and ANY queries. The Direct 
Response field shows the total number of DNS queries that the GSLB ServerIron ADX has 
responded to directly. 

Syntax: show gslb global-stat

Displaying the default GSLB policy

Use the show gslb default command to view the default GSLB policy settings for the ServerIron 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:

ServerIronADX(config)# show gslb default



  Default metric order: ENABLE



  Metric processing order:



                1-Server health check



                3-Round trip time between remote ServerIronADX and client



                4-Geographic location



                5-Remote ServerIronADX's available session capacity



                6-Server flashback speed



                7-Least response selection

This display shows the following information. 

TABLE 22

GSLB policy information 

This field...

Displays...

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.
