I'm configuring CoS on a QFX5100 for the first time and would appreciate some guidance around what happens to the default CoS components when you configure custom CoS components.
For example, the QFX Traffic Management Guide states that "If you explicitly configure one type of classifier but not other types of classifiers, the system uses only the configured classifier and does not use default classifiers for other types of traffic." I'm using a BA classifier to assign traffic with certain DSCP markings to queue 5. Does this mean that I also need to explicity configure a default classifier to handle all other unicast and multicast traffic?
Also, does configuring a custom scheduler overwrite the default schedulers in the default scheduler-map?
Unfortunately I don't have access to a test environment where I can see the effect that my configuration changes will have, so any guidance / experiences would be appreciated!
