Configuring Telephony OUI
VoIP devices attached to the switch can be identified by the vendor’s
Organizational Unique Identifier (OUI) in the source MAC address of received
packets. OUI numbers are assigned to vendors 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.
Use the Traffic > VoIP (Configure OUI) page to configure this feature.
Parameters
These parameters are displayed:
◆ 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. 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. (Default: FF-FF-FF-00-00-00)
◆ Description – User-defined text that identifies the VoIP devices.
Web Interface
To configure MAC OUI numbers for VoIP equipment:
1. Click Traffic, VoIP.
2. Select Configure OUI from the Step list.
3. Select Add from the Action list.
4. Enter a MAC address that specifies the OUI for VoIP devices in the network.
5. Select a mask from the pull-down list to define a MAC address range.
6. Enter a description for the devices.
