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.
