DESCRIPTION

HA Status

The text before the slash shows whether the device is configured as the

 

master or the backup role.

 

This text after the slash displays the monitored interface’s status in the

 

virtual router.

 

Active - This interface is up and using the virtual IP address and subnet

 

mask.

 

Stand-By- This interface is a backup interface in the virtual router. It is

 

not using the virtual IP address and subnet mask.

 

Fault - This interface is not functioning in the virtual router right now. In

 

active-passive mode (or in legacy mode with link monitoring enabled), if

ZyWALL forces all of its interfaces to the fault state so the backup

 

ZyWALL can take over all of the master ZyWALL’s functions.
