Virtual Router
The master and backup ZyWALL/USG form a single 'virtual router'. In the following example,
master ZyWALL/USG A and backup ZyWALL/USG B form a virtual router.
Chapter 31 Device HA
DESCRIPTION
Turn the ZyWALL/USG's device HA feature on or off.
Note: It is not recommended to use STP (Spanning Tree Protocol) with device HA.
This displays whether the ZyWALL/USG is currently set to use active-passive mode device
HA. Active-passive mode is recommended for general device failover deployments.
Click the link to go to the screen where you can configure the ZyWALL/USG to use the
device HA mode that it is not currently using.
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.
These are the names of the interfaces that are monitored by device HA.
This is the interface's IP address and subnet mask. Whichever ZyWALL/USG is the master
uses this virtual router IP address and subnet mask.
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/USG whether it is in master or
backup mode.
This tells whether the monitored interface's connection is down or up.
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 if one of the master ZyWALL/USG's interfaces loses its connection, the master
ZyWALL/USG forces all of its interfaces to the fault state so the backup ZyWALL/USG can
take over all of the master ZyWALL/USG's functions.
Click Apply to save your changes back to the ZyWALL/USG.
Click Reset to return the screen to its last-saved settings.
