Hi All,
I'm observing output drops on the gig 0/0 on the provider facing interface. The line is not exceeding bandwidth based on a one month view.
I don't think this is a speed/duplex issue and provider says no issues found.
Looking at the policy applied seems all drops are on the class-default. The config has nothing configured under the class-default. It's blank. Is by leaving this blank be the cause as to why I am seeing drops? I can't see any reason why we should have drops?
Thanks
