VLAN Membership Policy Server - provides a centralized server for selecting the VLAN for a port dynamically based on the MAC address of the device connected to the port.
VMPS uses a UDP port to listen to VQP (VLAN Query Protocol) requests from clients, so, it is not necessary for VMPS clients to know if the VMPS resides on a local or remote device on the network.
Upon receiving a valid request from a VMPS client, a VMPS server searches its database for an entry of a MAC-address to VLAN mapping.
When a port is configured as "dynamic," it receives VLAN information based on the MAC-address that is on the port.
The VLAN is not statically assigned to the port; it is dynamically acquired from the VMPS based on the MAC-address on the port.
SECURE MODE: If MAC has not been found in VMPS Server - shut down the port
On VMPS Server:
(config)# vmps server [ipaddress | hostname] primary
On all the switches in the LAN (VMPS Clients):
(config-if)# switchport access vlan dynamic
Define how many times you want Client to contact the Server, like if you want to retry 5 times:
(config)# vmps retry 5
(config)# vmps reconfirm 30 <--- RETRY IN 30 MINUTES IF 5 ATTEMPTS FAIL

You can assign switch ports to V LAN's dynamically, based on the source MAC address of the device connected to the port.When you move a host from a port on one switch in the network to a port on another switch in the network, the switch dynamically assigns the new port to the proper VLAN for that host.

Hello,
ReplyDeleteWhat is the source IP address of the VMPS query?
