QoS&VLAN
The equipment supports 802.1Q/P protocol and DiffServ configuration. Use of a Virtual LAN (VLAN)
allows voice and data traffic to be separated.
Chart 1 shows a network switch with no VLAN. Any broadcast frames will be transmitted to all other
ports. For example, and frames broadcast from Port 1 will be sent to Ports 2, 3, and 4.
Chart 2 shows an example with two VLANs indicated by red and blue. In this example, frames
broadcast from Port 1 will only go to Port 2 since Ports 3 and 4 are in a different VLAN. VLANs can be
used to divide a network by restricting the transmission of broadcast frames.
Note: In practice, VLANs are distinguished by the use of VLAN IDs.
