hi

case 1:

switch---IP Phone---PC

int f0/1

switchport access vlan 100

switchport trunk native vlan 100

switchport voice vlan 200

switchport trunk enc dot1q

switchport mode trunk

cdp enable

(option)

power inline auto

since voice vlan is taged, QoS for voice is needed.

Re: Voice Vlan

On newer switches you don't have to switchport mode trunk.

The trunk is auto-negotiated.

All you need is:

switchport access vlan (vlan)

switchport voice vlan (vlan)

Nothing more, nothing less.
