Avaya 1600 Series Manuel D’Utilisation

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. 

 

VLANSEP is “0” 

(Off/Disabled), 

OR the telephone is 

not tagging frames,

OR the telephone is 

tagging frames with a 

VLAN ID equal to 

PHY2VLAN.

Frames received on the secondary Ethernet 

interface will not be changed before 

forwarding. For example, tagging is not added 

or removed and the VLAN ID and tagged 

frames priority are not changed. The Ethernet 

switch forwarding logic determines that frames 

received on the Ethernet line interface are 

forwarded to the secondary Ethernet interface 

or to the telephone without regard to specific 

VLAN IDs or the existence of tags.

VLANSEP is “1” (On/Enabled)

All tagged frames received on the secondary 

Ethernet interface are changed before 

forwarding to make the VLAN ID equal to the 

PHY2VLAN value and the priority value equal 

to the PHY2PRIO value. 
Untagged frames received on the secondary 

Ethernet interface are not changed before 

forwarding.
