Configuring An External Switch Port - Avaya 9600 Series Installing And Administering

VLAN separation modes in 9600 Series IP Deskphones
9600 Series IP Deskphones support three VLAN separation modes:
• No VLAN separation mode: The CPU port of the phone receives untagged and tagged VLAN
frames on any VLAN irrespective of whether the phone sends untagged or frames. This
traffic is received from the PC port or the LAN port. The CPU filters the frames. To reduce
unnecessary traffic to the CPU, you must configure only the necessary VLANs on the
external switch port, in particular, voice VLAN and data VLAN. To configure the phone to
work in this mode, set VLANSEP=0.
• Partial VLAN separation mode: This is the default mode. In this mode, the CPU port sends
tagged packets to voice VLAN only. The CPU port receives tagged packets on voice VLAN or
untagged packets from LAN port. PC and LAN port can send any traffic between them. To
configure the phone to work in this mode, ensure the following conditions :
- VLANSEP = 1
- VLANSEPMODE = 0
- L2Q = 0 (auto) or 1 (tag)
- VLANTEST = 0 or timer is less than VLANTEST
- PHY2VLAN = 0
• Full VLAN separation mode: The CPU port of the phone receives tagged frames with VLAN
ID=L2QVLAN whether they are from the LAN port or PC port. The PC port receives untagged
or tagged frames with VLAN ID=PHY2VLAN from the LAN port. The PC port cannot send
any untagged frames or tagged frames with any VLAN ID, including the voice VLAN ID, to
the CPU. Frames received externally on the PC port can only be sent to the LAN port if they
are untagged frames or tagged frames with VLAN ID= PHY2VLAN. In this mode, there is a
complete separation between the CPU port and the PC port. To configure the phone to work
in this mode, ensure the following conditions:
- VLANSEP = 1
- VLANSEPMODE = 1
- L2Q = 0 (auto) or 1 (tag)
- L2QVLAN is not equal to 0
- PHY2VLAN is not equal to 0
- L2QVLAN is not equal to PHY2VLAN
The DHCP server on voice VLAN is reachable and the phone receives the IP address on voice
VLAN when the phone sends tagged VLAN frames.

Configuring an external switch port

About this task
It is important to restrict the VLAN binding in no VLAN separation mode. This is because the
internal phone switch does not filter the frames and the CPU of the phone is subjected to all the
traffic going through the phone. In full VLAN separation mode, the internal phone switch filters any
