Protocol Based Auto VoIP

Use the Protocol Based Auto VoIP page to configure the protocol-based Auto VoIP priority settings and to enable or disable the protocol-based Auto VoIP mode on the interfaces.

To access this page, click QoS > Auto VoIP > Protocol Based Auto VoIP in the navigation menu.

Use the buttons to perform the following tasks:

To configure the settings for one or more interfaces, select each entry to modify and click Edit.
To apply the same settings to all interfaces, click Edit All.
If you change any of the settings on the page, click Submit to send the updated configuration to the switch. Configuration changes take effect immediately. These changes will not be retained across a power cycle unless a Save is performed.
Click Refresh to update the page with the most current data from the switch.

Protocol Based Auto VoIP Fields

Field	Description
Auto VoIP VLAN	The VLAN used to segregate VoIP traffic from other non-voice traffic. All VoIP traffic in a session identified by the call-control protocol gets assigned to this VoIP VLAN.
Prioritization Type	The 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.
802.1p Priority	The 802.1p priority used for protocol-based VoIP traffic. This field can be configured if the Prioritization Type is 802.1p Priority. If the Auto VoIP mode is enabled and the interface detects a call-control protocol, the device marks traffic in that session with the specified 802.1p priority value to ensure voice traffic always gets the highest priority throughout the network path. Egress tagging must be administratively enabled on the appropriate uplink port to carry the remarked priority at the egress port.
Traffic Class	The traffic class used for protocol-based VoIP traffic. This field can be configured if the Prioritization Type is Traffic Class. If the Auto VoIP mode is enabled and the interface detects a call-control protocol, the device assigns the traffic in that session to the configured CoS (Class of Service) queue. Traffic classes with a higher value are generally used for time-sensitive traffic. The CoS queue associated with the specified traffic class should be configured with the appropriate bandwidth allocation to allow priority treatment for VoIP traffic.
Interface	The interface associated with the rest of the data in the row. When editing Auto VoIP settings on one or more interfaces, this field identifies the interface(s) being configured.
Auto VoIP Mode	The administrative mode of the Auto VoIP feature on the interface: Enable: The interface scans incoming traffic for the following call-control protocols: Session Initiation Protocol (SIP) H.323 Skinny Client Control Protocol (SCCP) Disable: The interface does not use the Auto VoIP feature to scan for call-control protocols.
Operational Status	The operational status of an interface. To be up, an interface must be administratively enabled and have a link.
