cat 3550 qos is my weakest area but i'll give it a try.
you must enable qos globally on the 3550 before it will work.

Note: Others may have a more complete answer

  Subject: Per-Port Per-VLAN marking
  Date: Sun, 20 Aug 2006 06:48:23 +0200
  Hi all,

  I had the following challange...

  On a switch (3550) mark all incoming traffic from VLAN x with
  precedence
  4
  As I understand I should use per-port per-vlan marking
  Right now I configure

  class-map match-all PREC4
  match vlan X
  policy-map PREC
  class PREC4
  set ip precedence 4

  when I apply this policy-map to a interface on a switch assume fa0/6
  the
  map would be rejected because I need another one more statement under
  class-map config. This is what I understand.
  So I configure an access-list 101 and with match access-group I apply
  it
  as an additional statement into the class map
  But right now I'm not sure if this really works...
  Maybe anyone here had anything like this configured an can send an
  example ??!

  thanks
  Udo
