802.1Q support

The IP Phone 2001, IP Phone 2002, IP Phone 2004, IP Phone 2007 and IP
Audio Conference Phone 2033 support 802.1Q. The IP Softphone 2050
supports 802.1Q through the PC’s operating system. This support enables the
definition of virtual LANs (VLANs) within a single LAN. This improves
bandwidth management, limits the impact of broadcast and multicast
messages, and simplifies VLAN configuration and packet prioritization. A
higher level of security between network segments can be achieved.

Configuration of 802.1Q on IP Phones

The 802.1Q support for the IP Phones is configured and controlled using the
IP Phone’s user interface or DHCP. The DHCP approach eliminates the need
to manually configure the VLAN ID during the installation.
To configure 802.1Q, configure the following:
• “p” bits
• VLAN ID
