scenario that a major power interruption is causing the phones to restart. Always allow time for 
network routers, the DHCP servers, etc. to be returned to service. If the telephone restarts for 
any reason and the VLANTEST time limit expires, the telephone assumes the administered 
VLAN ID is invalid. The telephone then initiates registration with the default VLAN ID.

Setting VLANTEST to “0” has the special meaning of telling the phone to use a non-zero VLAN 
indefinitely to attempt DHCP. In other words, the telephone does not return to the default VLAN.

Note:

If the telephone returns to the default VLAN but must be put back on the 
L2QVLAN VLAN ID, you must Reset the telephone. See the Reset procedure in 
the Avaya one-X™ Deskphone Value Edition 1600 Series IP Telephones 
Installation and Maintenance Guide.

VLAN separation controls whether or not traffic received on the secondary Ethernet interface 
can be forwarded on the voice VLAN. VLAN separation also controls whether network traffic 
received on the data VLAN can be forwarded to the telephone. The following system 
parameters control VLAN separation:

●

VLANSEP - enables (1) or disables (0) VLAN separation. The default is 1 (on), which 
allows full separation. When set to 0 (off), VLAN IDs are not used as a criteria for 
forwarding frames.

●

L2Q - 802.1Q tagging must be set to 1 (on) or 0 (auto).

●

L2QVLAN - must be set to the non-zero VLAN ID of the voice VLAN.

●

PHY2VLAN - must be set to the non-zero VLAN ID of the data VLAN, which cannot be the 
same as the voice VLAN ID.

●

PHY2PRIO - the layer 2 priority value to be used for tagged frames received on the 
secondary Ethernet interface. 

 provides several VLAN separation guidelines.
