Configuring VMPS
Beginning in privileged EXEC mode, follow these steps to change the reconfirmation interval:
To return the switch to its default setting, use the no vmps reconfirm global configuration command.

Changing the Retry Count

Beginning in privileged EXEC mode, follow these steps to change the number of times that the switch
attempts to contact the VMPS before querying the next server:
To return the switch to its default setting, use the no vmps retry global 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.

Step 2 vmps reconfirm minutes Enter the number of minutes between reconfirmations of the dynamic
VLAN membership. The range is 1 to 120. The default is 60 minutes.
Step 3 end Return to privileged EXEC mode.
Step 4 show vmps Verify the dynamic VLAN reconfirmation status in the Reconfirm Interval
field of the display.
