Monitoring the VMPS
Youcan display information about the VMPS by using the show vmps privileged EXEC command. The
switchdisplays this informationabout the VMPS:
•VMPSVQP Version—The version of VQP used to communicate with the VMPS. The switch queries
theVMPS that is using VQP Version 1.
•ReconfirmInterval—The number of minutes the switch waits before reconfirming the
VLAN-to-MAC-addressassignments.
•ServerRetry Count—The number of times VQP resends a query to the VMPS. If no response is received
afterthis many tries, the switch starts to query the secondary VMPS.
•VMPSdomain server—The IP address of the configured VLAN membership policy servers. The switch
sendsqueries to theone markedcurrent. The one marked primary is the primary server.
•VMPSAction—The resultof themost recentreconfirmation attempt. A reconfirmationattempt can
occurautomatically when the reconfirmation interval expires, or you can force it by entering the vmps
reconfirmprivileged EXEC command or its Network Assistant or SNMP equivalent.
