How are you monitoring this for oversub? SNMP graphs for pps/bps are not useful nor his looking at CLI pps/bps counters. You should monitor if there are queue drops on egress. If possible also monitor queue length, but not all platforms offer this information. My friend Occam says you're probably dropping packets. You could also subscribe to the stream with monitoring PC which runs something like this https://github.com/tarko/CCmon -- ++ytti
