DESCRIPTION
Turn the ZyWALL'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 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.
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 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 whether it is in master or backup mode.
This tells whether the monitored interface's connection is down or up.
