PC Port issues on Yealink Phones

[Jensen_Yealink]

The purpose of VLAN configurations on the IP phone is to insert tag with VLAN information to the packets generated by the IP phone. When VLAN is properly configured for the ports (Internet port and PC port) on the IP phone, the IP phone will tag 
all packets from these ports with the VLAN ID. The switch receives and forwards the tagged packets to the corresponding VLAN according to the VLAN ID in the tag as described in IEEE Std 802.3.  So the VID should be changed to corresponding setting on switch.
VWhen a regular PC connect to IP phone via PCport, both PC and IP phone to be trunked through the same physical Ethernet cable.
