  Hi all,

  I have been googling and testing without any luck and would
  appreciate
  any guidance from anyone.

  A port has already been configured on the CISCO switch with the
  following:
  interface FastEthernet2/0/1
  description VOIP VLAN 100
  switchport access vlan 100
  switchport mode access
  duplex full
  speed 100

  I plugged the phone into the port and everything worked as far as
  VOIP
  is concerned.

  Then I plug a PC into the PC port of the Polycom phone with the hope
  that I only need one port to support 2 devices.
  (I wanted the VOIP phone to use VLAN 100 and PC just the native VLAN)

  PROBLEM: However, I found that I could not get the PC (using DHCP) to
  get an IP address at all. It seems to be that the traffic from the PC
  is
  also tagged as VLAN 100 as well.
  I was told by others that there is a setting on the Polycom phone
  which
  allows the traffic of the PC, under this type of settings, to go
  native.

  Can anyone please help?

  Thanks.
