interface/ethernet/switch/qos/port

Syscap: rbswitch and crs_prestera Type: Directory

This sub-menu configures QoS settings for individual switch ports. It allows you to assign a QoS profile to ingress packets arriving on a specific port. If the port is configured as trusted, the assigned profile can be overridden by match rules based on packet header values.

By default, all ports are untrusted and receive the default QoS profile (Best-Effort, PCP=0, DSCP=0). In this default state, priority fields are cleared from egress packets.

Port Resources/Usage

Danger Due to hardware limitations, some switch chip models may break traffic flow while accessing QoS port usage data. Use port usage for diagnostics/troubleshooting only. For monitoring, use QoS monitor or Port stats instead.
