Displaying and Adding Telephony OUI
The
Telephony OUI
page lists the Organizationally Unique Identifiers (OUIs)
associated with different voice VLANs.
To display this page, click

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
Configuring OUI Based Voice and Media
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:

Configuring OUI Based Voice and Media
You can use the
Telephony OUI Based Auto VoIP
page to:
•
Configure an IEEE 802.1p priority level for Voice and Media traffic identified
using the OUI digits in MAC addresses.
•
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
Creating VLANs
).
•
Enable ports for this feature. When enabled on a port, the port is
automatically made member of the configured voice VLAN when the switch
receives an OUI frame (the administrator does not need to manually add the
port as a member of the VLAN).
