The Telephony OUI page lists the Organizationally Unique Identifiers (OUIs) 
associated with different voice VLANs. 

To display this page, click VLAN Management > Voice and Media > Telephony 
OUI in the navigation window.

The Telephony OUI Table is preconfigured with identifiers for commonly used 
telephony devices. The administrator can add or remove OUIs. When Voice and 
Media is enabled, ports use the OUI digits in the source and/or destination MAC 
addresses of incoming packets to automatically assign voice traffic to a voice 
VLAN. See 

 for instructions on 

associating the VLAN with an IEEE 802.1p priority and enabling ports for Voice and 
Media. 

To add a new OUI description:

Click Add.

Specify the following values:

•

Telephony OUI—Enter a 3-octet identifier for the telephony application.

•

Description—Enter a description of the service such as the vendor name or 
telephony product.

Click Apply and Close.

Specify the VLAN for OUI-based VoIP packets. Although you can assign a 
VLAN ID that has not yet been created on the switch, you must 
subsequently create the VLAN for the feature to be operational (see
