Hi, QoS expert
I tried to put QoS in a WS-C3560CG-8TC-S version 12.2(55)EX2.
It shows 0 traffic in class-map.
Here is the config
My question is why I can not see the traffic via class-map?
it should in the default Q if incorrect mark.
I erased the config and config with the autoQoS, shows the same result.
Let me know and thanks.

Hello Dahua, Adam,
Yes, it is a famous limitation regarding the "show policy-map interface" and documented by bug CSCso80701.
Just like Adam mentionned you can use 'show mls qos interface....[stat]' to get some infos instead.
===========================================
Symptom: "show policy-map interface" shows no matches
Conditions:
This command is run on one of the following switches:
2950 / 2960 / 2970 / 3550 /3560 /3750
Workaround:
This is a hardware limitation and these switches do not support this output. There is no workaround.
===========================================
Best regards.

A lot of the time the 'sh policy map interface' command in a switching environment will simply show you what is applied to the interface. Try issuing a 'sh mls qos interface g0/8' or 'sh mls qos interface g0/8 stats'.
Thanks,
Adam
