Hi Joey,
Configuration-wise, WRR (Weighted Round Robin) and SRR (Shaped Round Robin) are very similar. You can use the examples in this lesson:
Something to keep in mind is that a lot of commands will only show up in your configuration if you use non-default values. Here’s an example:
Switch#show running-config | incl mls
mls qos
QoS has been enabled on this switch, that’s the only command we have in our config. Let’s check the default cos-dscp map:
Switch#show mls qos maps cos-dscp
Cos-dscp map:
cos: 0 1 2 3 4 5 6 7
--------------------------------
dscp: 0 8 16 24 32 40 48 56
If you try to add this to your config, it won’t show up. Here’s an experiment:
Switch(config)#mls qos map cos-dscp 0 8 16 24 32 40 48 56
Switch(config)#do sh run | incl qos
mls qos
It doesn’t show up since these are the default values. Only if we change something it will show up:
Switch(config)#mls qos map cos-dscp 0 8 16 24 32 40 48 60
Switch(config)#do sh run | incl qos
mls qos map cos-dscp 0 8 16 24 32 40 48 60
mls qos
Now you can see it in the config. There is another way though…if you use show running-config all then you will see everything, including the defaults:
Switch#show running-config all | incl mls
mls qos rewrite ip dscp
mls qos
mls qos cos 0
mls qos dscp-mutation Default DSCP Mutation Map
The mls qos cos 0 and mls qos dscp-mutation Default DSCP Mutation Map are found on the interfaces.
