Hi Andrew,
I'm not sure if I understand what your answer is. Policing is done at
ingress. If you are talking about the process of setting the DSCP it is
done at egress using DSMARK. I don´t know (talk with Patrick or Stef) if by
using IMQ (as I understand it is some kind of virtual interface, not sure,
either) you could install a DSMARK on this interface to mark packets when
entering the router. Really don´t know. Again I´m not sure if I am
understanding the sense of your answer.
If you are not hurry do not hesitate to contact me again, but I'm always
late with my e-mail replies.
Best regards,
Leonardo Balliache
