3560 QoS Issues

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,

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
