Configuring VMPS

The switch cannot be a VMPS server but can act as a client to the VMPS and communicate with it
through the VLAN Query Protocol (VQP). VMPS dynamically assigns dynamic access port VLAN
membership.

Understanding VMPS
When the VMPS receives a VQP request from a client switch, it searches its database for a
MAC-address-to-VLAN mapping. The server response is based on this mapping and whether or not the
server is in secure mode. Secure mode determines whether the server shuts down the port when a VLAN
is not allowed on it or just denies the port access to the VLAN.
In response to a request, the VMPS takes one of these actions:
•

"Understanding VMPS" section on page 12-27
"Default VMPS Configuration" section on page 12-30
"VMPS Configuration Guidelines" section on page 12-30
"Configuring the VMPS Client" section on page 12-31
"Monitoring the VMPS" section on page 12-34
"Troubleshooting Dynamic Port VLAN Membership" section on page 12-34
"VMPS Configuration Example" section on page 12-35
If the assigned VLAN is restricted to a group of ports, the VMPS verifies the requesting port against
this group and responds as follows:
If the VLAN is allowed on the port, the VMPS sends the VLAN name to the client in response.
–
If the VLAN is not allowed on the port and the VMPS is not in secure mode, the VMPS sends
–
an access-denied response.
If the VLAN is not allowed on the port and the VMPS is in secure mode, the VMPS sends a
–
port-shutdown response.
Purpose
Set the spanning-tree path cost to 30 for VLAN 2.
Set the spanning-tree path cost to 30 for VLAN 3.
Set the spanning-tree path cost to 30 for VLAN 4.
Return to global configuration mode.
Repeat Steps 9 through 11 on Switch 1 interface Fast Ethernet 0/2, and
set the spanning-tree path cost to 30 for VLANs 8, 9, and 10.
Return to privileged EXEC mode.
Verify your entries.
In the display, verify that the path costs are set correctly for interfaces
Fast Ethernet 0/1 and 0/2.
(Optional) Save your entries in the configuration file.
