Syntax: show gslb policy

In this example, the default order of the policy metrics is in effect. Metrics that are disabled by 
default (such as the administrative preference) are not listed. 

In the following example, the order has been changed, two of the metrics have been disabled, and 
the administrative preference has been enabled.

Flashback appl-level delay 
tolerance

Indicates the percentage of difference that can exist between application level 
FlashBack response times for two sites, without the ServerIron ADX preferring 
one site over the other based on this metric.

TCP-level delay tolerance

Indicates the percentage of difference that can exist between Layer 4 
FlashBack response times for two sites, without the ServerIron ADX preferring 
one site over the other based on this metric.
