The Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE have an
internal Ethernet switch, enabling forwarding of packets to the phone, and to the
access port and the network port on the back of the phone.
If a computer is connected to the access port, the computer and the phone share

shared physical link has the following implications for the VLAN configuration
on the network:
