SUMMARY STEPS
1. enable
2. configure terminal
3. interface interface-id
4. switchport mode trunk
5. switchport voice vlan vlan-id
DETAILED STEPS
Voice Traffic and VVID
The HWICs can automatically configure voice VLAN. This capability overcomes the management
complexity of overlaying a voice topology onto a data network while maintaining the quality of voice
traffic. With the automatically configured voice VLAN feature, network administrators can segment
phones into separate logical networks, even though the data and voice infrastructure is physically the
same. The voice VLAN feature places the phones into their own VLANs without the need for end-user
intervention. A user can plug the phone into the switch, and the switch provides the phone with the
necessary VLAN information.
