 Chapter 39 Device HA

ZyWALL USG 1000 User’s Guide

The Configuration > Device HA General screen lets you enable or disable 
device HA, and displays which device HA mode the ZyWALL is set to use along 
with a summary of the monitored interfaces.

Figure 450   Configuration > Device HA > General     

The following table describes the labels in this screen.   

Table 178   Configuration > Device HA > General

Enable Device 
HA

Turn the ZyWALL’s device HA feature on or off.

Note: It is not recommended to use STP (Spanning Tree Protocol) 

with device HA.

Device HA 
Mode

This displays whether the ZyWALL is currently set to use active-passive 
mode device HA or legacy mode device HA. Active-passive mode is 
recommended for general device failover deployments. Only use legacy 
mode if you need a more complex relationship between the master and 
backup ZyWALLs, such as active-active or using different ZyWALLs as 
the master for individual interfaces. 

The master and its backups must all use the same device HA mode. 

Click the link to go to the screen where you can configure the ZyWALL to 
use the device HA mode that it is not currently using. 

Monitored 
Interface 
Summary

This table shows the status of the interfaces that you selected for 
monitoring in the other device HA screens.

#

This is the entry’s index number in the list.

Interface

These are the names of the interfaces that are monitored by device HA.

Virtual Router 
IP /  Netmask

This is the interface’s IP address and subnet mask. Whichever ZyWALL is 
the master uses this virtual router IP address and subnet mask. 

Management 
IP / Netmask

This field displays the interface’s management IP address and subnet 
mask. You can use this IP address and subnet mask to access the 
ZyWALL whether it is in master or backup mode.

Link Status

This tells whether the monitored interface’s connection is down or up.
