Displaying weighted hash-based GSLB persistence
The following command will show the list of active DNS domain IPs of a zone, weight value
configured for each IP, number of hash buckets allocated for each IP and usage counter for each IP.
Syntax: show gslb phash active-ip [all | zone-name <name> host-name <name>]
The command should be used on Barrel Processors only. User should use the "rconsole <slot>
<processor>" command to go the desired Barrel Processor and should use this command on the
Barrel Processor.
Here is the sample output of this command.
ServerIronADX# show gslb phash active-ip all
