Chapter 10      Understanding and Configuring VLANs, VTP, and VMPS
VLAN Membership Policy Server
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:
Data traffic to and from the PC that is connected to the switch through the access port of the IP phone 
(access VLAN)
Voice traffic to and from the IP phone (voice VLAN)
Reconfirming VLAN Memberships
To confirm the dynamic port VLAN membership assignments that the switch has received from the 
VMPS, perform this task:
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:
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
