Description: The number of discarded cells due to combined CLP=0 and CLP=1 UPC/NPC policing.

What is atmfM4VpUpcNpcCurrDiscardedCells?

Counts the total number of ATM cells discarded on a Virtual Path during the current interval because they violated the Usage Parameter Control or Network Parameter Control traffic contract, considering both CLP=0 and CLP=1 cells together. Elevated counts indicate traffic policing is actively dropping out-of-contract cells.
