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
of 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
In this mode, phone can send and receive Ethernet frames that are tagged voice VLAN ID
(L2QVLAN). If there is a DHCP server on this LAN that is reachable by this phone, then this server
can also send and receive tagged frames with he same VLAN ID.
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.
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
tagged VLAN frames with VLANs other than voice VLAN and data VLAN. However, you must
configure only the necessary VLANs on the external switch port.
Procedure
1. Bind VLAN to the voice VLAN, that is L2QVLAN, and the data VLAN, that is PHY2VLAN.
2. Set the default VLAN as the data VLAN.
This data VLAN is the VLAN assigned by the external switch port to untagged frames
received from the phone LAN port.
3. 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.
When egress voice VLAN frames are sent untagged from the external switch port to the
phone LAN port, there is no VLAN separation between the voice VLAN and data VLAN.
