T ELEPHONY OUI
Use the Voice VLAN OUI Table to identify VoIP devices attached to the
switch. VoIP devices can be identified by the manufacturer’s Organizational
Unique Identifier (OUI) in the source MAC address of received packets. OUI
numbers are assigned to manufacturers and form the first three octets of
device MAC addresses. The MAC OUI numbers for VoIP equipment can be
configured on the switch so that traffic from these devices is recognized as
VoIP.
N OTE :
Making any changes to the OUI table will restart the auto-detection
process for attached VoIP devices.
