DESCRIPTION

Device Role

Select the device HA role that the ZyWALL plays in the virtual router. Choices are:

 

Master - This ZyWALL is the master ZyWALL in the virtual router. This ZyWALL

 

uses the virtual IP address for each monitored interface.

 

Note: Do not set this field to Master for two or more ZyWALLs in the

 

same virtual router (same cluster ID).

 

Backup - This ZyWALL is a backup ZyWALL in the virtual router. This ZyWALL

 

does not use any of the virtual IP addresses.

 

 

Priority

This field is available for a backup ZyWALL. Type the priority of the backup

 

ZyWALL. The backup ZyWALL with the highest value takes over the role of the

 

master ZyWALL if the master ZyWALL becomes unavailable. The priority must be

 

between 1 and 254. (The master interface has priority 255.)

 

 

Preempt

This field is available for a backup ZyWALL. Select this if this ZyWALL should

 

become the master ZyWALL if a lower-priority ZyWALL is the master when this one

 

is enabled. (If the role is master, the ZyWALL preempts by default.)

 

 

Cluster Settings

Click Advanced to display more settings. Click Basic to display fewer settings.

 

 

Cluster ID

Type 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.
