46 CHAPTER 4: CONFIGURING THE SWITCH IP Phone Prioritization Use the IP Phone Prioritization section to enable or disable traffic prioritization for NBX or other IP phones. Table 14 lists the available options for this section. CAUTION: To ensure that the Switch recognizes the NBX or other IP phone during phone initialization, do not connect any data source to the phone until the phone has finished booting up. Once the phone is available for use, any data source (for example, a computer) can then be connected to the phone's pass-through port. This only applies if you use a single wall jack for your network connection and use the pass-through LAN port on the IP phone. Table 14 IP Phone Prioritization Options Option Description Enable NBX Phone Prioritization Select to automatically detect and prioritize traffic from all NBX phones that are connected to the Switch. By default, this option is selected. Enable Phone MAC Address-based Prioritization If you are not using NBX phones and you know the Organizational Unique Identifier (OUI) for the phones, select this option, and then type the OUI in the fields provided. If this option is selected and the OUI specified, the Switch will automatically detect these phones and prioritize traffic to and from them. An OUI (sometimes called 'vendor ID') is the first 24 bits of a MAC address for a network-connected device (in this case, a phone), which indicate the specific vendor for that device. Disable Phone Prioritiza- Select to disable traffic prioritiza- tion tion for IP phones on the Switch If you change any of these settings, click Apply in the IP Phone Prioritization section to save your changes. List of Detected Phones This section displays the MAC addresses of IP phones that are detected and given priority by the Switch. To display a phone that is connected to a port, select the port from the drop-down list.
