Vlan tagging - newbie question 2

[Bujitsu]

Hi,

I have a ip telephone (not Cisco) that that has a 2 lan ports 1 for connection to a swtch and another port for a pc. The ip phone can set the vlan id (say vlan 10), but the pc cannot set the vlan id, however the PC must be in vlan 20.
How do I set up the cisco 3550 port to enable traffic to flow to the correct vlans?

Regards.

Usually the IP Phone expects the PC to send un-tagged packets, it is the access VLAN the switchport is in that determines which VLAN they are on.

interface FastEthernet0/1
switchport access vlan 20
switchport mode access
switchport voice vlan 10

This configures the switchport for what you require. It creates a psudo-trunk if you like, that has one tagged VLAN (Voice) and one untagged VLAN (Access). Usually the trickiest part is getting the IP Phone to discover the Voice VLAN automatically....
