GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches 5. If the interface mode is VLAN ID or Dot1p, specify the VLAN ID or 802.1p priority value in the Value field. 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 the Apply button. 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) 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. 2. In the Prioritization Type list, select method used to prioritize VoIP traffic when a call-control protocol is detected, which is one of the following: • Remark. Remark the voice traffic with the specified 802.1p priority value at the ingress interface. • Traffic Class. Assign VoIP traffic to the specified traffic class when egressing the interface. 3. In the Class Value list, select the CoS tag value to be reassigned for packets received on the voice VLAN when Remark CoS is enabled. 4. Select the interface to configure.

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) 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
.
2.
In the Prioritization Type list, select method used to prioritize VoIP traffic when a call-control
protocol is detected, which is one of the following:
Remark
. Remark the voice traffic with the specified 802.1p priority value at the
ingress interface.
Traffic Class.
Assign VoIP traffic to the specified traffic class when egressing the
interface.
3.
In the Class Value list, select the CoS tag value to be reassigned for packets received on the
voice VLAN when Remark CoS is enabled.
4.
Select the interface to configure.
For information about how to select and configure one or more ports, see
Configuring

In the Auto VoIP Mode list, select
Enable
to enable Auto VoIP on the selected interfaces.
