Hi all,
I need some help on QoS on IOS-XR. I've Juniper QoS configuration and need a support to convert the same to IOS XR. I'm not well in Juniper.
#run show configuration class-of-service
Juniper QoS config as follows.

#### more schedulars like these
I have converted it to IOS-XR up to certain level. But need some support to complete it.
