7.2 Handover Management
The handover releases a connection with an existing AP and connects to a new AP.
It provides seamless wireless LAN connection to a wireless terminal. The APC provides
both 802.11 standard handover and Samsung’s unique AirMove (Network Controlled
Handover) handover.
7.2.1
Connection History Information
Use the ‘show station association history [MAC_ADDRESS]’ command to check the
handover history information of a specific wireless terminal connected to the APC.
7.2.2
AirMove Configuration
Unlike the 802.11 standard handover where a wireless terminal performs the handover
function by itself, the AirMove handover is performed by the collaboration between
wireless terminals compatible with the APC. Therefore, the packet loss or handover time is
optimized. Some Samsung smartphones such as Galaxy S2 or S3, etc. provide the AirMove
function.
Configuration using CLI
To configure the AirMove related function, execute the following command to go to the
handover configuration mode.
WEC8500# configure terminal
WEC8500/configure# handover
