82 Avaya 1600 Series IP Deskphones Administrator Guide
On receipt of a LLDPDU message, the Avaya IP Telephones will act on the TLV elements
described in Table11:
Avaya Proprietary 802.1Q Framing 802.1Q Framing = 1 if tagging or 2 if not.
Subtype = 7.
Basic Mandatory End-of-LLDPDU Not applicable.

Name Impact
PHY2VLAN IEEE 802.1 Port
VLAN ID
System value changed to the Port VLAN identifier in
the TLV.
L2QVLAN and
L2Q
IEEE 802.1 VLAN
Name
The system value is changed to the TLV VLAN
Identifier. L2Q will be set to 1 (ON).
VLAN Name TLV is only effective if:
●The telephone is not registered with the Call
Server.
●Name begins with VOICE (case does not
matter).
●The VLAN is not zero.
●DHCP Client is activated.
●The telephone is registered but is not tagging
layer 2 frames with a non-zero VLAN ID.
If VLAN Name causes the telephone to change
VLAN and the telephone already has an IP Address
the telephone will release the IP Address and reset.
If the TLV VLAN ID matches the VLAN ID the
telephone is using, the VLAN ID is marked as set by
LLDP. Otherwise, if already registered, the
telephone waits until there are no active calls,
releases its IP Address, turns on tagging with the
TLV VLAN ID, sets L2Q to "on," changes the default
L2Q to "on," and resets. If there is no valid IP
Address, the telephone immediately starts tagging
with the new VLAN ID without resetting.
