Telephony OUI
OUIs are assigned by the Institute of Electrical and Electronics Engineers, Incorporated
(IEEE) Registration Authority. Since the number of IP phone manufacturers is limited and
well-known, the known OUI values cause the relevant frames, and the port on which they are
seen, to be automatically assigned to a Voice VLAN.
The OUI Global table can hold up to 128 OUIs.
This section covers the following topics:
•
Telephony OUI Table
•
Telephone OUI Interface
Telephony OUI Table
Use the Telephony OUI page to configure Telephony OUI QoS properties. In addition, the
Auto Membership Aging time can be configured. If the specified time period passes with no
telephony activity, the port is removed from the Voice VLAN.
Use the Telephony OUI page to view existing OUIs, and add new OUIs.
To configure Telephony OUI and/or add a new Voice VLAN OUI:
Click VLAN Management > Voice VLAN > Telephony OUI.
The Telephony OUI page contains the following fields:
•
Telephony OUI Operational Status—Displays whether OUIs are used to identify
voice traffic.
•
CoS/802.1p—Select the CoS queue to be assigned to voice traffic.
•
Remark CoS/802.1p—Select whether to remark egress traffic.
•
Auto Membership Aging Time—Enter the time delay to remove a port from the voice
VLAN after all of the MAC addresses of the phones detected on the ports have aged out.
Click Apply to update the Running Configuration of the device with these values.
The Telephony OUI table appears:
•
Telephony OUI—First six digits of the MAC address that are reserved for OUIs.
•
Description—User-assigned OUI description.
Click Restore Default OUIs to delete all of the user-created OUIs, and leave only the default
OUIs in the table. The OUI information may not be accurate until the restoration is completed.
