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
frames 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
