User Guidelines
The classification of a packet from VoIP equipment/phones is based on the
packet’s OUI in the source MAC address. OUIs are globally assigned
(administered) by the IEEE.
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.
Since the number of IP phone manufacturers that dominates the market is limited
and well known, the known OUI values are configured by default and OUIs can be
added/removed by the user when required.
Example
The following example adds an entry to the voice VLAN OUI table.
switchxxxxxx(config)# voice vlan oui-table add 00:AA:BB experimental
