mani,

My 3550 running c3550-i5q3l2-mz.121-20.ea1.bin will not mark on a Layer-2 port
based on a class that only has "match any". The following combo works for me
to mark all IP traffic.

access-list 101 permit ip any any

class-map match-all ipanyany
  match access-group 101
!
!
policy-map prec
  class ipanyany
    set ip precedence 5

interface FastEthernet0/24
 switchport mode dynamic desirable
 service-policy input prec

HTH,

  First of all is this a Layer 3 routed port or a layer 2 port?

> Hi Guys,

  switch port to ip precedence critical. Pls check the following config, if
  I configure like this what will happen to default class(25% of bw). So if
  traffic exceeds 75% remaining will be assigned a defalt precedence value of
  0, should I make max reserve-bandwidth 100 or for default-class to should
I
  assign ip precedence of 0.(ie class class-default/set ip precedence 5) Any
  help is appreciated.
