VLAN Management Policy Server
(重定向自VLAN membership policy server)
A VLAN Management Policy Server or "VMPS" is a network switch that contains a mapping of device information to VLAN.
The primary goal of VMPS is VLAN assignment for general network management purposes, but can also be used for providing security through segregating clients with an unknown MAC address, or through further extension of the protocol to provide login for Cisco AClS. This last functionality is now deprecated by Cisco, in favour of 802.1X, and as the VMPS technology is Cisco proprietary, the VLAN assignment can now be carried out in the 802.1X framework.
