Reading a policy map

[lkadlik]

Hi,

I wanted to know, in this policy map

policy-map 75_24
class ef
  priority percent 75
  set ip dscp ef
class af41
  bandwidth percent 24
class class-default
  fair-queue
  set ip dscp default

Is everything getting set back to default before it leaves the router? Is this read from the top down with the last entry being the one that wins ?

It is read top-down. But first match wins i.e. once a packet matches a particular entry, it exits. If it doesn't match any of the entries then it uses the last default entry.

Of course from your config you are missing the class-match stattements that define what traffic matches each class.

HTH,

Ian
