Volume 3 - Layer 2 Configurations Chapter Overview Voice VLAN Notational information OUI (Organizationally Unique Identifier) - An OUI are the first 3 octets of a MAC address. The OUI of voice VLAN is used to identify the voice traffic. The following table shows the default IP phone vendors OUI: Voice Device - Like an IP phone, the voice device sends voice traffic. OUI 00:E0:BB 00:03:6B 00:E0:75 00:D0:1E 00:01:E3 00:60:B9 00:0F:E2 00:09:6E Vendor 3COM Cisco Veritel Pingtel Siemens NEC/ Philips Huawei-3COM Avaya Table 18-1 Default IP phone vendors OUI Voice Packet - A packet is determined as voice packet if the source MAC addresses of packets comply with the IP phone vendors OUI. Manual Mode - If a port works in manual mode, you should add the port to the voice VLAN or remove the port from the voice VLAN through manual configuration. Voice VLAN Process Voice Packets When voice VLAN is enabled in a switch, the switch will add a VLAN tag with the specified voice VLAN ID and the specified priority to the received untagged voice packets. The received packets are determined as voice packets if the source MAC addresses of packets comply with the organizationally unique identifier (OUI) addresses configured by the switch. The following figure 2 illustrates how to handle the received untagged and tagged voice packets. DGS-6600 Configuration Guide 175
