CLI – This example configures VoIP traffic settings for port 2 and displays the
current Voice VLAN status.
Configuring Telephony OUI
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.
Command Attributes
• Telephony OUI – Specifies a MAC address range to add to the list. Enter the MAC
address in format 01-23-45-67-89-AB.
• Mask – Identifies a range of MAC addresses. Selecting 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. Selecting FF-FF-FF-FF-FF-FF
specifies a single MAC address. (Default: FF-FF-FF-00-00-00)
• Description – User-defined text that identifies the VoIP devices.
