Technical Note: Auto Voice VLAN Detection and Configuration

Introduction

This application note describes the procedure to enable and configure the “Auto Voice VLAN Detection and

Configuration” feature on the BES50 switches. With this feature when connecting the BES50 to a compatible

Nortel IP phone, the BES50 switch automatically detects the presence of the IP phone and assigns the

appropriate VLAN membership to its Ethernet port. This is achieved by the Link Layer Discovery Protocol

message exchange between the BES50 switch and the IP phone. The IP phone learns the voice VLAN

membership information carried in the LLDP messages, and configures its Ethernet port accordingly. The

BES50 switch expects Ethernet frames originated from the IP phone are tagged with the appropriate VLAN ID,

and it also tags all outgoing frames towards the IP phone with the same voice VLAN ID.

Software/Firmware Lineup

The “Auto Voice VLAN Detection and Configuration” feature on the BES50 switches is designed to work

with designated Nortel IP phone. Please check software or firmware version of the Nortel IP phone and

the BES50 switches to ensure this feature is supported. The following BES50 switches and Nortel IP

phones were tested in this application note:

Device Model Firmware/Software

BES50 FE BES50FE-24T PWR 1.0.3.0

BES50 GE BES50GE-24T PWR 1.0.5.0

IP Phone 2001 NTDU90 0604DBG

IP Phone 2002 NTDU91 0604DAD

IP Phone 2004 NTDU92 0604DBG

IP Phone 1120E NTYS03 0624C4N

IP Phone 1140E NTYS05 0625C4D

IP Phone 1220 NTYS19 062AC57

IP Phone 1230 NTYS20 062AC57

Please ensure the BES50 switches are using at least the software version specified in this application

note (or later software version). Consult the document “Using the Nortel Business Ethernet Switch 50

Series” (NN47924-301) for the detailed software upgrade procedures.
