We have a few devices where the Port-Channel (or Bundle-Ether) virtual aggregation interfaces have traffic discrepancies to their respective physical Ten Gigs.
For example, over a 1 week view of the exact same timeframe:
Te1 = Max IN 5 Gbps
Te2 = Max IN 5 Gbps
Port-Channel1 (Te1/Te2) = Max IN 14 Gbps (+4 Gbps)
These devices can also sometimes exceed 5 minute polling time, can this also cause a traffic discrepancy problem like this?
