Configuring Dynamic VLAN Membership
Voice Ports
If a VVID (voice VLAN ID) is configured on a dynamic access port, the port can belong to both an
access VLAN and a voice VLAN. Consequently, an access port configured for connecting an IP phone
can have separate VLANs for the following:
•

Reconfirming VLAN Memberships
To confirm the dynamic port VLAN membership assignments that the switch has received from the
VMPS, perform this task:
Command
Step 1
Switch# vmps reconfirm
Step 2
Switch# show vmps
Configuring Reconfirmation Interval
VMPS clients periodically reconfirm the VLAN membership information received from the VMPS. You
can set the number of minutes the VMPS client waits before reconfirming the VLAN-to-MAC-address
assignments.
To configure the reconfirmation interval, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# vmps reconfirm minutes
Step 3
Switch(config)# end
Step 4
Switch# show vmps
This example shows how to change the reconfirmation interval to 60 minutes and verify the change:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# vmps reconfirm 60
Switch(config)# end
Switch# show vmps
