5 Configuration D-Link Web Smart Switch User Manual Aging Time: Enter a period of time (in hours) to remove a port from the voice VLAN if the port is an automatic VLAN member. When the last voice device stops sending traffic and the MAC address of this voice device is aged out, the voice VLAN aging timer will start. The port will be removed from the voice VLAN after the expiration of the voice VLAN aging timer. Selectable range is from 1 to 120 hours, and default is 1 hour. From Port / To Port: A consecutive group of ports may be configured starting with the selected port. Auto Detection: Switch will add ports to the voice VLAN automatically if it detects the device OUI matches the Telephony OUI configured in the Voice VLAN OUI Setting page. Use the drop-down menu to enable or disable the OUI auto detection function. The default is Disabled Click Apply to implement changes made. Note: Voice VLAN has higher priority than any other features (including QoS). Therefore the voice traffic will be operated according to the Voice VLAN setting and not impacted by the QoS feature. Configuration > Voice VLAN > Voice VLAN OUI Setting This window allows the user to configure the user-defined voice traffic's OUI. An Organizationally Unique Identifier (OUI) is the first three bytes of the MAC address. This identifier uniquely identifies a vendor, manufacturer, or other organization. Figure 62 - Configuration > Voice VLAN > Voice VLAN OUI Setting There are some pre-defined OUIs and when the user configures personal OUI, these pre-defined OUIs must be avoided. Below are the pre-defined voice traffic's OUI: OUI Vendor Mnemonic Name 00:E0:BB 3Com 3com 00:03:6B Cisco cisco 00:E0:75 Veritel veritel 00:D0:1E Pingtel pingtel 00:01:E3 Siemens siemens 00:60:B9 NEC/ Philips nec&philips 00:0F:E2 Huawei-3COM huawei&3com 00:09:6E Avaya avaya Default OUI: Pre-defined OUI values, including brand names of 3COM, Cisco, Veritel, Pingtel, Siemens, NEC/Philips, Huawei3COM, and Avaya. User defined OUI: You can manually create a Telephony OUI with a description. The maximum number of user defined OUIs is 10. It will occupy one ACL rule when selecting a user defined OUI by default, and to configure one user-defined OUI will take extra one ACL rule. System will auto generate an ACL profile (Profile ID: 51) for all the Voice VLAN rules. 36
