You an do port-based qos or vlan-based qos. (Depending on the TCAM chip used
on the platform). Look into vlan-based qos. I know the 3550's and 3750's can
do this, the syntax is alittle different per platform.

	Is there any way to classify incoming traffic on
2950/3550/3560/3750/4500(SupV) based on VLAN it was received in? For
example, if I wanted all traffic in VLAN 10 to be af12 (or have it policed),
I would do something like:

class-map match-any SomeVLAN
  match vlan 10
!
policy-map Bleh
  class SomeVLAN
   set dscp af21
!
interface GigabitEthernet 0/1
  service-policy input Bleh
!

	Needless to say, the above doesn't seem to be possible. Are there
any other ways? Note, the incoming DSCP is untrusted and IP's/MAC's are
beyond my the administrative control.

Kind regards,
Marko.
