Administering A Vlan - Avaya J169 Installing And Administering

Administering your phone
• Conference room: This scenario is similar to that at a public desk, but when the user
disconnects the laptop, the deskphone reregisters with the room extension.
• Shared desk with shared computer: This scenario is similar to a desktop computer
connected to an office phone. However in this case, the desktop computer supports multiple
user login accounts as users share the PC and the phone by working on different shifts.
• Contact center: The desktop computer connected to the deskphone runs a contact center
program. When an agent logs in to the computer, the phone automatically registers the user
to a call server. The agent must log in to the call center separately. The agent also has the
option to log in through an agent login Feature Access Code (FAC) to the contact center
program. When the agent logs out of the computer, the phone unregisters, and hence, the
agent logs out of the call center.

Administering a VLAN

This section contains information on how to administer Avaya J100 Series IPPhones Avaya J100
Series IP Phones to minimize registration time and maximize performance in a Virtual LAN
(VLAN) environment. If your LAN environment does not include VLANs, set the system parameter
L2Q to 2 (off) to ensure correct operation.

About VLAN Tagging
IEEE 802.1Q tagging (VLAN) is a useful method of managing VoIP traffic in your LAN. You can
establish a voice VLAN, set L2QVLAN to the VLAN ID of that VLAN, and provide voice traffic with
priority over other traffic. If LLDP was used to set the VLAN for the deskphones, that setting has
absolute authority. Otherwise, you can set VLAN tagging manually, by DHCP, or in the
46xxsettings.txt file.
If VLAN tagging is enabled (L2Q=0 or 1), the IP Deskphones set the VLAN ID to L2QVLAN, and
VLAN priority for packets from the deskphone to L2QAUD for audio packets and L2QSIG for
signaling packets. The default value (6) for these parameters is the recommended value for voice
traffic in IEEE 802.1D.
Regardless of the tagging setting, a IP Deskphone will always transmit packets from the
deskphone at absolute priority over packets from the secondary Ethernet interface from an
attached PC. The priority settings are useful only if the downstream equipment is administered to
give the voice VLAN priority.
