VLAN separation modes
Avaya J100 Series IP Phones supports two VLAN separation modes:
• No VLAN separation mode: In this mode, the CPU port of the port receives untagged frames
and tagged VLAN frames on any VLAN irrespective of whether the phone sends untagged or
tagged frames. This traffic can be received from the PC port or LAN port. The filtering of the
frames is done by the CPU itself. In order to reduce unnecessary traffic to the CPU, the
administrator should configure only the necessary VLANs on the external switch port, in
particular, voice VLAN and data VLAN.
• Full VLAN separation mode: This is the default mode. In this mode, the CPU port of the
phone receives tagged frames with VLAN ID = L2QVLAN whether they are from the LAN port
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
