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.

Technical Note: Auto Voice VLAN Detection and Configuration Step 2: Enable Link Layer Discovery Protocol (LLDP) The Auto Voice VLAN detection feature uses LLDP for the IP phone and the BES50 to discover each other, and to exchange voice VLAN information. • From the WebUI, navigate to the Applications > LLDP > Configuration panel. • Selected the checkbox labeled Enabled. • Select and press the Submit button. Version NN70000-002 issue 1.
Technical Note: Auto Voice VLAN Detection and Configuration Step 3: Enable Global Voice VLAN Detection In order to use the auto voice VLAN detection, this feature must first be enabled on a global basis. • • • • From the WebUI, navigate to the Applications > Auto Device Detection > Voice VLAN > Global Settings panel. Selected the checkbox labeled Auto Detection Status. Fill the Voice VLAN ID created in Step 1 (in our previous example VLAN ID 10) Select and press the Submit button.

Technical Note: Auto Voice VLAN Detection and Configuration Step 4: Enable Per-Port Voice VLAN Detection The final configuration step is to enable voice VLAN detection on the ports in which IP phones may connect to. While both the BES50FE and BES50GE switch need to enable the same “Voice VLAN Mode” attribute, the WebUI panels of these two switches are slightly different. The following screenshot illustrates the configuration procedure for BES50GE.
Technical Note: Auto Voice VLAN Detection and Configuration Step 5: Connect IP Phone to BES50 Connect a compatible Nortel IP phone to the port with auto voice VLAN detection enabled (e.g. port 5 in the previous example). Step 6: Check Auto Voice VLAN Detection Status After the IP phone is connected, wait for the IP phone and the BES50 switch discover each other. The following simple steps can be used to check whether the Voice VLAN is automatically configured when the IP phone is connected.

Technical Note: Auto Voice VLAN Detection and Configuration Appendix A: Nortel IP Phone Configuration The “Auto Voice VLAN Detection and Configuration” feature on the BES50 switches is designed to work with designated Nortel IP phone. The IP phone must support Link Layer Discovery Protocol (LLDP), able to learn voice VLAN membership information carried in the LLDP messages, and have the capability to configure its Ethernet port according to the received VLAN information.
