Actually, I've seen some other equipment store more than 32 bits... and it's Cisco gear! Catalyst 1924/2820, to be exact. But the implementation is different. There are two variables, like swPortTxTotalOctets and swPortTxTotalOctetsWraps. The formula to get the actual byte count is, of course, (swPortTxTotalOctetsWraps << 32) | swPortTxTotalOctets -Phil
