Note:
Note: Table8 applies to all 1600 Series IP Telephones. Certain 1600 IP Telephones
might have additional, optional information that you can administer. For more
information, see Chapter 8: Administering Applications and Options.
VLAN Considerations
If your LAN environment does not include Virtual LANs (VLANs), ignore this section. Otherwise,
this section contains information on how to administer 1600 Series IP Telephones to minimize
registration time and maximize performance in a VLAN environment.

VLAN Tagging

IEEE 802.1Q tagging (VLAN) is a useful method of managing VoIP traffic in your LAN. Avaya
recommends that you establish a voice LAN, set L2QVLAN to that VLAN, and provide voice
traffic with priority over other traffic. If LLDP was used to set the telephones’ VLAN, that setting
TPSLIST " " (Null) One or more trusted domain/path strings, separated by
commas without any intervening spaces (0-255 ASCII
characters, including commas). A URL pushed to a
telephone must contain one of these strings if it is to be
used to obtain content to be rendered by the
telephone.
UNNAMEDSTAT 1 Unnamed Registration Status. Specifies whether
unnamed registration is initiated if the user fails to enter
a value at the Extension: prompt or Login screen.
Unnamed registration provides the telephone with a
TTI-level service, enabling a user, for example, to dial
emergency services like 911. Value 1=Yes, 0=No.
VLANSEP 1 VLAN separation. Controls whether frames to/from the
secondary Ethernet interface receive IEEE 802.1Q
tagging treatment. The tagging treatment enables
frames to be forwarded based on their tags in a
manner separate from telephone frames. If tags are not
changed, no tag-based forwarding is employed. Values
are: 1=On/Enabled, 0= Off/Disabled. This parameter is
used with several related parameters. For more
information, see VLAN Separation on page 75.
VLANTEST 60 Number of seconds to wait for a DHCPOFFER when
using a non-zero VLAN ID (1-3 ASCII digits, from “0” to
“999”).
