Settings
Device Role Select the Device HA role that the ZyWALL/USG plays in the virtual router. Choices are:
Master - This ZyWALL/USG is the master ZyWALL/USG in the virtual router. This
ZyWALL/USG uses the virtual IP address for each monitored interface.
Note: Do not set this field to Master for two or more ZyWALL/USGs in the same virtual
Backup - This ZyWALL/USG is a backup ZyWALL/USG in the virtual router. This ZyWALL/
USG does not use any of the virtual IP addresses.
Priority This field is available for a backup ZyWALL/USG. Type the priority of the backup ZyWALL/
USG. The backup ZyWALL/USG with the highest value takes over the role of the master
ZyWALL/USG if the master ZyWALL/USG becomes unavailable. The priority must be
between 1 and 254. (The master interface has priority 255.)
Enable This field is available for a backup ZyWALL/USG. Select this if this ZyWALL/USG should
Preemption become the master ZyWALL/USG if a lower-priority ZyWALL/USG is the master when this
one is enabled. (If the role is master, the ZyWALL/USG preempts by default.)
Cluster Settings
Cluster ID Type the cluster ID number. A virtual router consists of a master ZyWALL/USG and all of
its backup ZyWALL/USGs. If you have multiple ZyWALL/USG virtual routers on your
network, use a different cluster ID for each virtual router.
Authentication Select the authentication method the virtual router uses. Every interface in a virtual
router must use the same authentication method and password. Choices are:
None - this virtual router does not use any authentication method.
Text - this virtual router uses a plain text password for authentication. Type the
password in the field next to the radio button. The password can consist of alphanumeric
characters, the underscore, and some punctuation marks (+-/*= :; .! @$&%#~ ' \ () ),
and it can be up to eight characters long.
IP AH (MD5) - this virtual router uses an encrypted MD5 password for authentication.
Type the password in the field next to the radio button. The password can consist of
alphanumeric characters, the underscore, and some punctuation marks (+-/*= :; .!
@$&%#~ ' \ () ), and it can be up to eight characters long.
Monitored This table shows the status of the Device HA settings and status of the ZyWALL/USG's
Interface interfaces.
