Chapter 10 Device HA

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.
