Configuring VMPS
This is an example of output for the show vmps privileged EXEC command:
Switch# show vmps
VQP Client Status:
--------------------
VMPS VQP Version: 1
Reconfirm Interval: 60 min
Server Retry Count: 3
VMPS domain server: 172.20.128.86 (primary, current)
172.20.128.87
Reconfirmation status

VMPS Action: No Dynamic Port
Troubleshooting Dynamic Port VLAN Membership
The VMPS shuts down a dynamic port under these conditions:
• The VMPS is in secure mode, and it does not allow the host to connect to the port. The VMPS shuts
down the port to prevent the host from connecting to the network.
• More than 20 active hosts reside on a dynamic port.
To re-enable a disabled dynamic port, enter the no shutdown interface configuration command.
VMPS Configuration Example
Figure 16-5 shows a network with a VMPS server switch and VMPS client switches with dynamic ports.
In this example, these assumptions apply:
• The VMPS server and the VMPS client are separate switches.
• The Catalyst 6500 series Switch A is the primary VMPS server.
• The Catalyst 5000 series Switch C and Switch J are secondary VMPS servers.
• End stations are connected to the clients, Switch B and Switch I.
• The database configuration file is stored on the TFTP server with the IP address 172.20.22.7.
VMPS domain server The IP address of the configured VLAN membership policy servers. The switch
sends queries to the one marked current. The one marked primary is the primary
server.
VMPS Action The result of the most recent reconfirmation attempt. A reconfirmation attempt
can occur automatically when the reconfirmation interval expired, or you can
force it by entering the vmps reconfirm privileged EXEC command or its
SNMP equivalent.
