Re: OT: Catalys 6500 qos policing doubts

Hi Marc,

I am using something like this (at each input L2 interface i have only a
different type of traffic i need to mark, the config i sent you is a
simplified version ):

...
access-list 10 permit any

class-map class_in
 match access-group 10

policy-map pol_in1
 class class_in
  set dscp dscp1

policy-map pol_in2
 class class_in
  set dscp dscp2
policy-map pol_in3
 class class_in
  set dscp dscp3

interface TenGigabitEthernet2/3/14
 switchport
 switchport access vlan 200
 switchport mode access
 platform qos queue-mode mode-dscp
 service-policy input pol_in1

interface TenGigabitEthernet2/3/15
 switchport
 switchport access vlan 20
 switchport mode access
 platform qos queue-mode mode-dscp
 service-policy input pol_in2

interface TenGigabitEthernet2/3/16
 switchport
 switchport access vlan 2
 switchport mode access
 platform qos queue-mode mode-dscp
 service-policy input pol_in3
....

This is, i am using a different policy-map at each input interface to mark
with a different dscp value

Regards.
