A Roaming Assist policy enables a group of access points (APs) to constantly monitor a given client's packets and received signal strength indicator (RSSI) to determine which among them is the optimal AP for the client to use for roaming. The system then forces the client to connect to the optimal AP.
Specify a roaming aggressiveness value for wireless clients. Configuring this value increases the client‘s roaming capabilities in scenarios where the client‘s location is likely to change drastically and suddenly. For example, when a client hops on to a train that speeds up quickly. In such a scenario, the AP receives a maximum of 2 (two) messages from the client that have a relatively low RSSI values. This results in a decaying-average, which is above the specified handover-threshold value. Consequently, the client is unable to roam.
