DMS-3130 Series Multi-Gigabit L3 Stackable Managed Switch Web UI Reference Guide Parameter Mode Description Select the mode here. Options to choose from are: • Auto Untagged - Specifies that voice VLAN untagged membership will be automatically learned. • Auto Tagged - Specifies that voice VLAN tagged membership will be automatically learned. • Manual - Specifies that voice VLAN membership will be manually configured. If auto-learning is enabled, the port will automatically be learned as a voice VLAN member. This membership will automatically be aged out. When the port is working in the auto-tagged mode and the port captures a voice device through the device's OUI, it will join the voice VLAN as a tagged member automatically. When the voice device sends tagged packets, the Switch will change its priority. When the voice device sends untagged packets, it will forward them in the Port VLAN ID (PVID). When the port is working in auto-untagged mode, and the port captures a voice device through the device's OUI, it will join the voice VLAN as an untagged member automatically. When the voice device sends tagged packets, the Switch will change its priority. When the voice device sends untagged packets, it will forward them in the voice VLAN. When the Switch receives LLDP-MED packets, it checks the VLAN ID, tagged flag, and priority flag. The Switch should follow the tagged flag and priority setting. Click the Apply button to accept the changes made. Voice VLAN OUI This window is used to display and configure the voice VLAN OUI (Organizationally Unique Identifier) settings. Use this window to add a user-defined OUI for the voice VLAN. The OUI for the voice VLAN is used to identify the voice traffic by using the voice VLAN function. If the source MAC address of the received packet matches any of the OUI patterns, the received packet is determined as a voice packet. The user-defined OUI cannot be the same as the default OUI. The default OUI cannot be deleted. To view the following window, click L2 Features > VLAN > Voice VLAN > Voice VLAN OUI, as shown below: Figure 5-33 Voice VLAN OUI Window 132
