Active-Passive Mode Edit Monitored Interface - ZyXEL Communications USG40 User Manual

41.5 Active-Passive Mode Edit 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/USG 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.
A bridge interface's Device HA settings are not retained if you delete the bridge interface.

DESCRIPTION
Select this to have Device HA monitor the status of this interface's connection.
This identifies the interface.
Note: Do not connect the bridge interfaces on two ZyWALL/USGs without Device HA
activated on both. Doing so could cause a broadcast storm.
Either activate Device HA before connecting the bridge interfaces or disable the bridge
interfaces, connect the bridge interfaces, activate Device HA, and finally reactivate the
bridge interfaces.
This is the interface's (static) IP address and subnet mask in the virtual router. Whichever
ZyWALL/USG is currently serving as the master uses this virtual router IP address and
subnet mask. These fields are blank if the interface is a DHCP client or has no IP settings.
