Configuring 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:
• Adding OUIs to the Telephony OUI Table
• Adding Interfaces to Voice VLAN on Basis of OUIs
