DESCRIPTION
Click this button to display a greater or lesser number of configuration
fields.
Select the device HA role that the NXC plays in the virtual router.
Choices are:
Master - This NXC is the master NXC in the virtual router. This NXC
uses the virtual IP address for each monitored interface.
Note: Do not set this field to Master for two or more NXCs in the
same virtual router (same cluster ID).
Backup - This NXC is a backup NXC in the virtual router. This NXC does
not use any of the virtual IP addresses.
This field is available for a backup NXC. Type the priority of the backup
NXC. The backup NXC with the highest value takes over the role of the
master NXC if the master NXC becomes unavailable. The priority must
be between 1 and 254. (The master interface has priority 255.)
This field is available for a backup NXC. Select this if this NXC should
become the master NXC if a lower-priority NXC is the master when this
one is enabled. (If the role is master, the NXC preempts by default.)
Type the cluster ID number. A virtual router consists of a master NXC
and all of its backup NXCs. If you have multiple NXC 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
NXC's interfaces.
Select an entry and click this to be able to modify it.
