Each access point keeps a subnet table that consists of a list of home agent IP addresses and their subnet masks. When a mobile device associates to an access point and has roamed into a foreign network, the access point performs a lookup on the subnet map table. The access point proceeds with the registration process.

You can click Refresh if the subnet table displayed appears out of date.

Home Agent

A router on the home network serving as the anchor point for communication with the access point. It transports packets from a device on the internet to the roaming mobile device. The mobility binding and visitor entry of the home agent is updated during reregistration. If registration is denied, the access point makes the necessary adjustments and attempts to register again. For example, if the registration is denied because of time mismatch, and the home agent sent back its time stamp for synchronization, the access point adjusts the time stamp in future registration requests.

Mask

The subnet mask to identify the subnetwork so the IP address be recognized by the LAN.
