Hello everyone,

We are looking for the information that we did not find in the documentation.

When we applied Trust DSCP on all interfaces and congestion appears on the uplink of this switch to the Core.

The field DSCP will be used to prioritize the packet in this congestion?

Please help me! Thank you!

Hi Qazik,

DSCP is a packet header value that can be used to request high priority or best-effort delivery for traffic.

By configuring trust dscp on all the interfaces, the default priority to be mapped for packets is changed from 802.1p to dscp.

If you are trying to configure priority mapping. If so, please check the example located as a reference.

I hope it helps!
