39.4 Configuring an Active-Passive Mode
Monitored Interface
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.
