What is aal5VccOverSizedSDUs?

This OID counts how many data packets were discarded on an ATM virtual circuit because they exceeded the maximum allowed size for the AAL5 protocol layer. The counter increments each time an oversized packet arrives and is dropped. An operator would monitor this to detect applications or devices sending packets that are too large for the network protocol.
