MQC Class-Based Generic Traffic Shaping

As the QoS sections are pending updates at the moment, I'm on a v4 rack at the moment completing these sections from the v5 workbook.

I've configured R6 as per the solution configurtion and I've generated traffic as suggested. When I try to examine the shaping statistics using the sugested command,"show policy-map interface fastEthernet 0/0.146", I am not seeing the same output as is given in the workbook. Is this due to a difference in IOS versions or am I missing something silly? Is there another way to see the shaping queue stats?

Workbook Output

Rack1R6#show policy-map interface fastEthernet 0/0.146

FastEthernet0/0.146 

  Service-policy output: SHAPE_VLAN146

  • Hi Jimmy,

    I remember such "problems" when going over QoS section. In my opinion, what's most important is the information content, not really the way is presented in the CLI. So yes, in this case it's IOS version related issue, your's being newer than the one being used when the workbook topic was developed.
