Avaya 4600 Manual Do Utilizador

 provides several VLAN separation guidelines. 

VLANSEP is “0” 
(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” (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.

VLANSEP is “1” 
(Enabled)

AND the telephone is 
not tagging frames, 

OR if the telephone is 
tagging frames with a 
VLAN ID equal to 
PHY2VLAN, 

OR if the PHY2VLAN 
value is zero.

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” 
(Enabled)

AND the telephone is 
tagging frames with a 
VLAN ID not equal to 
PHY2VLAN, 

AND the PHY2VLAN 
value is not zero.

Tagged frames received on the Ethernet line 
interface will only be forwarded to the secondary 
Ethernet interface if the VLAN ID equals 
PHY2VLAN. 
Tagged frames received on the Ethernet line 
interface will only be forwarded to the telephone 
if the VLAN ID equals the VLAN ID used by the 
telephone.
Untagged frames will continue to be forwarded 
or not forwarded as determined by the Ethernet 
switch forwarding logic.
