The 802.1Q support is available for IP Phone 2001, IP Phone 2002, IP Phone
2004, and the IP Softphone 2050 (through the PC's operating system).
The 802.1Q support is configured from the user display interface of the IP
Phone. Configure 802.1Q VLAN support when you initially configure an IP
Phone. The switch ports for Voice Gateway Media Card TLAN network
interfaces must be configured as untagged ports so the header is removed.
While the IP Phone 2001 provides VLAN support, it does not provide a port
for a PC.
The 802.1Q IEEE protocol standard allows virtual LANs (VLANs) to be
defined within a single LAN. This improves bandwidth management and
limits the impact of broadcast and multicast messages. A higher level of
security between segments in a network can also be achieved.
