Understanding How the Cisco Unified IP Phone Interacts with the
VLAN
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
the same physical link to the switch and share the same port on the switch. This
shared physical link has the following implications for the VLAN configuration
on the network:
•
The current VLANs might be configured on an IP subnet basis. However,
additional IP addresses might not be available to assign the phone to the same
subnet as other devices connected to the same port.
•
Data traffic present on the VLAN supporting phones might reduce the quality
of Voice-over-IP traffic.
•
Network security may indicate a need to isolate the VLAN voice traffic from
the VLAN data traffic.
