Thanks Petr,
My traffic is being marked on R5
However the counters on the switch are not incrementing.
Is this a bug, or is it normal (i.e. the counters only work in the outbound
direction)?

Pierre,
Basically, you cannot classify/mark traffic with class-default on 3550.
At least, it did not work with me :)
You need to match ip packets witch IP access-list, e.g.
class IP
match access-group 100
access-list 100 permit ip any any
policy-map MARK
class IP
set ip dscp 11
HTH

2006/5/28, Pierre-Alex <paguanel@hotmail.com>:
I am trying to accomplish the following (apparently very basic):
Diagram:
R5 --------------(fa0/5)---Switch--(fa0/4)------------------R4
Task:
On switch2 mark all packets coming from R5 with af11.
Do this on port fa 0/5
Configs:
On Switch:
interface FastEthernet0/5
switchport access vlan 34
switchport mode access
service-policy input r5-i
policy-map r5-i
class class-default
set dscp 11
Verification:
I am pinging R4 from R5 and checking the dscp received using a class-map
on
R4
As you can see, no packet is marked
On R4
r4#sh policy-map interface
Ethernet0/1.34
Service-policy input: marking
Class-map: af11 (match-all)
0 packets, 0 bytes
30 second offered rate 0 bps
Match: ip dscp af11 (10)
Class-map: class-default (match-any)
1006859 packets, 118805079 bytes
30 second offered rate 408000 bps, drop rate 0 bps
Match: any
Please note that configuring "mls qos trust dscp" removes the service
policy
from the interface . So adding this command does not solve the problem
Any idea?
Thanks
Pierre
