GS752TXS and GS728TXS Smart Switches • Untagged. Send untagged voice traffic. • Disable.Operationally disables the Voice VLAN feature on the interface. 5. If the interface mode is VLAN ID or Dot1p, specify the VLAN ID or 802.1p priority value under Value. This field is valid only when VLAN ID or dot1p is selected as the interface mode. 6. From the CoS Override Mode list, specify the CoS override mode for the selected ports: • Enabled. The port ignores the 802.1p priority value in the Ethernet frames it receives from connected devices. • Disabled. The port trusts the priority value in the received frame. 7. Click Apply. Auto-VoIP Configuration Voice over Internet Protocol (VoIP) enables telephone calls over a data network. Because voice traffic is typically more time-sensitive than data traffic, the Auto VoIP feature helps provide a classification mechanism for voice packets so that they can be prioritized above data packets in order to provide better Quality of Service (QoS). With the Auto VoIP feature, voice prioritization is provided based on call-control protocols (SIP, SCCP, H.323) and/or OUI bits. Configure Protocol-Based Auto VoIP Settings To prioritize time-sensitive voice traffic over data traffic, protocol-based Auto VoIP checks for packets carrying the following VoIP protocols: • Session Initiation Protocol (SIP) • H.323 • Signalling Connection Control Part (SCCP) VoIP frames that are received on ports that have the Auto VoIP feature enabled are marked with the specified CoS traffic class value. To configure the protocol-based port settings: 1. Select Switching Auto-VoIP > Protocol Based Port Settings. 112
