User Guidelines
The classification of a packet to Packets from VoIP Equipment/Phones is
based on the packet’s OUI of the source Mac Address.
In MAC addresses, the first three bytes contain a manufacturer ID
(Organizationally Unique Identifiers - OUI) and the last three bytes contain a
unique station ID.
OUIs are globally assigned (administered) by the IEEE.
Since the number of IP phones manufacturers that dominates the market is
limited and well known, the known OUI values can be configured (as a
default and user configurable) to the switch.
Example
The following example adds an entry to the voice VLAN OUI table.
Console(config)#
voice vlan oui-table add
00:AA:BB
