Virtual LAN (VLAN)

VLANs provide a means to segregate your network into distinct groups or domains. They also
provide a means to prioritize the network traffic into each of these distinct domains. For example,
a network may have a Voice VLAN and a Data VLAN. Grouping devices that have a set of
common requirements has the following advantages:
• greatly simplifies network design
• increases scalability
• improves security
• improves network management
The networking standard that describes VLANs is IEEE 802.1Q. This standard describes in detail
the 802.1Q protocol and how Ethernet frames get an additional four-byte tag inserted at the
beginning of the frame. This additional VLAN tag describes the VLAN ID that a particular device
belongs to and the priority of the VLAN tagged frame. Voice and video traffic typically get a higher
priority in the network as they are subject to degradation caused by network jitter and delay.

The Avaya J100 Series IP Phones has an internal network switch that is capable of using VLANs
to segregate traffic between the LAN port, the PC port and the internal port that goes to the CPU
of the phone. You can have VLAN functionality on this switch and configure the switch to isolate
the traffic destined for the CPU of the phone from the data destined to the PC port.
The configuration of the internal switch of the phone can be done through the
46xxsettings.txt file, LLDP or DHCP. It is preferable to configure the VLAN settings on the
