Step 6
Troubleshooting Dynamic-Access Port VLAN Membership
Problem
The VMPS shuts down a dynamic-access port under these conditions:
•
Problem
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.
• Problem More than 20 active hosts reside on a dynamic-access port.
Solution
To reenable a disabled dynamic-access port, enter the shutdown interface configuration command
followed by the no shutdown interface configuration command.
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:
•
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 expires, or you can force it by entering the vmps
reconfirm privileged EXEC command or its Network Assistant or SNMP equivalent.
