This Counter32 object counts good packets received by a port that are 1522 bytes or larger, excluding framing bits but including the FCS, noting that packets from 1523-1536 bytes increment only this counter while packets of 1537 bytes and above also increment rxExcessSizeDisc. An admin troubleshooting jumbo-frame or MTU mismatch issues on a link watches this counter to confirm oversized frames are actually arriving at the port. For example, a rising count here after enabling jumbo frames on an attached server would confirm the switch port is now receiving frames beyond the standard 1522-byte limit.
