Cluster ID
You can have multiple NWA3000-N series AP virtual routers on your network. Use 
a different cluster ID to identify each virtual router. In the following example, 
NWA3000-N series APs A and B form a virtual router that uses cluster ID 1. 
NWA3000-N series APs C and D form a virtual router that uses cluster ID 2.

Monitored Interfaces in Active-Passive Mode Device HA
You can select which interfaces device HA monitors. If a monitored interface on 
the NWA3000-N series AP loses its connection, device HA has the backup 
NWA3000-N series AP take over.
Enable monitoring for the same interfaces on the master and backup NWA3000-N 
series APs. Each monitored interface must have a static IP address and be 
connected to the same subnet as the corresponding interface on the backup or 
master NWA3000-N series AP.  
Virtual Router and Management IP Addresses
• If a backup takes over for the master, it uses the master’s IP addresses. These 
IP addresses are know as the virtual router IP addresses. 
• Each interface can also have a management IP address. You can connect to this 
IP address to manage the NWA3000-N series AP regardless of whether it is the 
master or the backup. 
For example, NWA3000-N series AP B takes over A’s 192.168.1.2 LAN interface IP 
address. This is a virtual router IP address. NWA3000-N series AP A keeps it’s LAN 
management IP address of 192.168.1.5 and NWA3000-N series AP B has its own 
LAN management IP address of 192.168.1.6. These do not change when 
NWA3000-N series AP B becomes the master.
