 Chapter 39 Device HA

ZyWALL USG 1000 User’s Guide

The Device HA Active-Passive Mode Monitored Interface Edit screen lets 
you enable or disable monitoring of an interface and set the interface’s 
management IP address and subnet mask. To access this screen, click 
Configuration > Device HA > Active-Passive Mode > Edit.

If you configure device HA settings for an Ethernet interface and later add the 
Ethernet interface to a bridge, the ZyWALL retains the interface’s device HA 
settings and uses them again if you later remove the interface from the bridge. If 
the bridge is later deleted or the interface is removed from it, Device HA will 
recover the interface’s setting.

Password

Enter the password used for verification during synchronization. Every 
ZyWALL in the virtual router must use the same password. 

If you leave this field blank in the master ZyWALL, no backup ZyWALLs 
can synchronize from it. 

If you leave this field blank in a backup ZyWALL, it cannot synchronize 
from the master ZyWALL.

Interval

When you select Auto Synchronize, set how often the ZyWALL 
synchronizes with the master.
