LANCOM GS-23xx: Voice-VLAN configuration and automatic assignment to IP telephones by means of OUI address



Description:
This document describes the configuration required on a LANCOM managed switch of the GS-23xx series in order to configure a voice VLAN and automatically assign it to an IP telephone by means of OUI address.

Note:
An OUI address consists of the first 24 bits of a MAC address. This is the manufacturer ID assigned by the IEEE. For LANCOM devices the OUI 00 is 00:A0:57.

4) Navigate to the menu QoS -> Port Shaping and set port 4 to a bandwidth of 500 Mbps.



5) Switch to the menu Voice LAN -> Configuration.

  • Enable the Voice LAN feature and set the VLAN ID to 200.
