Avaya J129 - External Switch Configuration

or the 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. In order to configure Avaya J100 Series IP Phones to work in this mode, all
the following conditions must be met:
- VLANSEPMODE = 1 (default)
- L2Q = 0 (auto, default) or 1 (tag)
- L2QVLAN is not equal to 0
- PHY2VLAN is not equal to 0
- L2QVLAN is not equal to PHY2VLAN
- The phone actually sends tagged VLAN frames. This means that the DHCP server on
voice VLAN (L2QVLAN) is reachable and the phone receives IP address on voice VLAN.
If one of these conditions is not met then the phone works in no VLAN separation mode where all
kinds of traffic reaches the CPU port of the phone.
Note:
The phone can send tagged VLAN frames on the voice VLAN (L2QVLAN), but still not work in
full VLAN separation mode. For example, when PHY2VLAN = 0 or VLANSEPMODE = 0.

External switch configuration
Configure the following for the external switch port:
• Bind VLAN to the voice VLAN (L2QVLAN) and the data VLAN (PHY2VLAN). It is important to
restrict the VLAN binding when in No VLAN separation mode. This is because there is no
filtering by the internal phone switch and the CPU of the phone is subject to all the traffic
going through the phone. When in Full VLAN separation mode, the internal phone switch will
filter any tagged VLAN frames with VLANs other than voice VLAN (L2QVLAN) and data
VLAN (PHY2VLAN) in any case. However, you must configure only the necessary VLANs on
the external switch port.
• Set the default VLAN as the data VLAN (PHY2VLAN). This is the VLAN assigned by the
external switch port to untagged frames received from phone LAN port.
• Configure one of the following for egress tagging:
- Data VLAN is untagged and voice VLAN is tagged.
- Data VLAN and voice VLAN are both tagged. You must configure this option to have Full
VLAN separation.
Sending egress voice VLAN frames untagged from the external switch port to the phone LAN port
means that there is no VLAN separation between the voice VLAN and data VLAN.
