Hello,
I don't understand under which conditions the cos-output-q map is used.
As an internal DSCP label is added to the packets following classification (for non IP packets, the
cos-dscp map would be used to assign a DSCP label, as documented in the attached diagram from the 3750X Cisco documentation),
all queuing should be done with this internal DSCP label.
So when is the cos-output-q used (the same question applies to the cos-input-q map)?
Thank you!
Arnaud
