I monitor a IBM8274 (which is a xylan switch resold by IBM). I monitor the 
ATM ports, but MIBII doesn't have normal interfaces.ifTable.ifEntry.ifInOctets
or interfaces.ifTable.ifEntry.ifOutOctets counters for the ATM ports.

I found a cell counter that seems to work in the enterprise mib. 
. (I don't have the symbolic name
handy, sorry) Take that and multiply by 48 or 53 (depending on your
religion ;) and you get a reasonable byte count for the port.
