• VoIP devices attached to the switch 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.
•
Setting a mask of FF-FF-FF-00-00-00 identifies all devices with the
same OUI (the first three octets). Other masks restrict the MAC address
range. Setting a mask of FF-FF-FF-FF-FF-FF specifies a single MAC
address.
