Hello Everyone,
I am struggling around with QoS configuration on a 3560.
I have configured the following:
class-map match-all VOICE
match access-group name VOICE
policy-map VOICE
class VOICE
set ip dscp ef
ip access-list extended VOICE
permit ip any any log
interface fastEthernet 0/1
service-policy input VOICE
If you see it is a straight forward QoS configuration for match everything. I did this as an example but I created a full class configuration with different networks for matching the signaling, mission critical traffic, etc.
The problem is that when I input a show policy-map int fa0/1 I don't see any counters. I don't see also any matches with the show access-list command.
mls qos is also enable.
Can anyone give me some help here?
Thanks,

That is because the 35xx implement QoS very differently that a router. It's more
Read the below link on QoS:-

Thanks for your response but your link is not applicable. I am configuring a 3560 not a 3550. The 3550 uses WRR for the queuing and 3560 Shaped Round Robing. Also the problems that I am having are regarding marking. I cannot see any hit counts. All the configuration has been made using the Cisco QoS SRND.
Any other ideas?

Good point - well spotted!
if you have read the QoS SRND - surely you also read the MLS QoS Verification Commands???
show mls qos
show mls qos map
show mls qos interface
show mls qos interface policers
show class-map
show policy-map
show policy interface
Which I think are the only real show commands you can use - but I have read a caveat somewhere that reads the show access-list and show policy-map commands do not really work on this platform.
Also once you have configured your Ingress marking and your Queueing, Dropping & Scheduling config....the only command that will show you anything is:-
show platform pm if-numbers
check to see the port value number of the interface you want to see stats about then:-
show platform port-asci stats drop port #

Hello Andrew,
Thanks again for the response. Let me build the full configuration again and use your show commands to check hit counts. I will get back to you today. A caveat looks like the issue.
Thanks again,
Juan
