DESCRIPTION
Click this button to display a greater or lesser number of configuration
fields.
Select the device HA role that the NWA3000-N series AP plays in the
virtual router. Choices are:
Master - This NWA3000-N series AP is the master NWA3000-N series
AP in the virtual router. This NWA3000-N series AP uses the virtual IP
address for each monitored interface.
Note: Do not set this field to Master for two or more NWA3000-N
series APs in the same virtual router (same cluster ID).
Backup - This NWA3000-N series AP is a backup NWA3000-N series AP
in the virtual router. This NWA3000-N series AP does not use any of the
virtual IP addresses.
This field is available for a backup NWA3000-N series AP. Type the
priority of the backup NWA3000-N series AP. The backup NWA3000-N
series AP with the highest value takes over the role of the master
NWA3000-N series AP if the master NWA3000-N series AP becomes
unavailable. The priority must be between 1 and 254. (The master
interface has priority 255.)
This field is available for a backup NWA3000-N series AP. Select this if
this NWA3000-N series AP should become the master NWA3000-N
series AP if a lower-priority NWA3000-N series AP is the master when
this one is enabled. (If the role is master, the NWA3000-N series AP
preempts by default.)
Type the cluster ID number. A virtual router consists of a master
NWA3000-N series AP and all of its backup NWA3000-N series APs. If
you have multiple NWA3000-N series AP 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.
