auto-voip protocol-based

Use this command to configure the global protocol-based auto VoIP remarking priority or traffic-class. If remark priority is configured, the voice data of the session is remarked with the priority configured through this command. The remark-priority is the 802.1p priority used for protocol-based VoIP traffic. If 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.

The tc value is the traffic class used for protocol-based VoIP traffic. If 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.

Note

You must enable tagging on auto VoIP enabled ports to remark the voice data upon egress.
