Once the frame comes into the switch and you have DSCP trusted, when it egresses a trunk we will use the DSCP -> Cos mapping table to mark COS. WebCommon options include interpreting PCP and DSCP fields according to user configuration. When a packet egresses the switch, a reverse process may rewrite PCP and/or DSCP headers according to packet priority. So far, mlxsw has supported prioritization based on PCP (802.1p priority tag). This patch set introduces support for prioritization based ...
