fields.

Device Role

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.

Priority

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.)

Enable 
Preemption

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.)

Cluster Settings
Cluster ID

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.

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.
