Configuring VMPS
Monitoring the VMPS
You can display information about the VMPS by using the show vmps privileged EXEC command. The
switch displays this information about the 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 VQP Version The version of VQP used to communicate with the VMPS. The switch queries
the VMPS that is using VQP version 1.
Reconfirm Interval The number of minutes the switch waits before reconfirming the
VLAN-to-MAC-address assignments.
Server Retry Count The number of times VQP resends a query to the VMPS. If no response is
received after this many tries, the switch starts to query the secondary VMPS.
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
Network Assistant or SNMP equivalent.
