Monitored Interfaces in Active-Passive Mode Device HA

You can select which interfaces device HA monitors. If a monitored interface on the ZyWALL

loses its connection, device HA has the backup ZyWALL take over.

Enable monitoring for the same interfaces on the master and backup ZyWALLs. Each

monitored interface must have a static IP address and be connected to the same subnet as the

corresponding interface on the backup or master ZyWALL.

Virtual Router and Management IP Addresses

• If a backup takes over for the master, it uses the master’s IP addresses. These IP addresses

are know as the virtual router IP addresses.

• Each interface can also have a management IP address. You can connect to this IP address

to manage the ZyWALL regardless of whether it is the master or the backup.

24.4 Active-Passive Mode Device HA Commands

The following table identify the values required for many of these commands. Other input

values are discussed with the corresponding commands.

The following sections list the

device-ha commands.

24.4.1 Active-Passive Mode Device HA Commands

This table lists the commands for configuring active-passive mode device HA.

Table 122 Input Values for device-ha Commands

LABEL DESCRIPTION

interface_name The name of the interface. This depends on the ZyWALL model.

For the ZyWALL USG 300 and above, use gex, x = 1 ~ N, where N equals the

highest numbered Ethernet interface for your ZyWALL model.

For the ZyWALL USG 100 and 200 models, use a name such as wan1, wan2,

opt, lan1, ext-wlan, or dmz.

Besides, in HA AP mode, the interface can also be a bridge interface.

In HA Legancy mode, the interface can also be a VLAN interface.

Table 123 device-ha ap-mode Commands

COMMAND DESCRIPTION

[no] device-ha ap-mode preempt Turn on preempt if this ZyWALL should become the

master ZyWALL if a lower-priority ZyWALL is the

master when this ZyWALL is enabled.

device-ha ap-mode role {master|backup} Sets the ZyWALL to be the master or a backup in

the virtual router.

device-ha ap-mode cluster-id <1..32> Sets the cluster ID number. A virtual router consists

of a master ZyWALL and all of its backup

ZyWALLs. If you have multiple ZyWALL virtual

routers on your network, use a different cluster ID

for each virtual router.
