DESCRIPTION
Click this button to display a greater or lesser number of configuration fields.
Select the device HA role that the device plays in the virtual router. Choices are:
Master - This device is the master device in the virtual router. This device uses
the virtual IP address for each monitored interface.
Note: Do not set this field to Master for two or more devices in the same virtual
router (same cluster ID).
Backup - This device is a backup device in the virtual router. This device does
not use any of the virtual IP addresses.
This field is available for a backup device. Type the priority of the backup device.
The backup device with the highest value takes over the role of the master
device if the master device becomes unavailable. The priority must be between 1
and 254. (The master interface has priority 255.)
This field is available for a backup device. Select this if this device should
become the master device if a lower-priority device is the master when this one
is enabled. (If the role is master, the device preempts by default.)
Type the cluster ID number. A virtual router consists of a master device and all of
its backup devices. If you have multiple device virtual routers on your network,
use a different cluster ID for each virtual router.
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.
This table shows the status of the device HA settings and status of the device's
interfaces.
Select an entry and click this to be able to modify it.
To turn on an entry, select it and click Activate.
To turn off an entry, select it and click Inactivate.
This is the entry's index number in the list.
The activate (light bulb) icon is lit when the entry is active and dimmed when the
entry is inactive.
This field identifies the interface. At the time of writing, Ethernet and bridge
interfaces can be included in the active-passive mode virtual router. The member
interfaces of any bridge interfaces do not display separately.
