I've unsucessfully tried to monitor PVCs. I opened a ticket
with marconi, and here's what they told me:

Sounds good eh? Unfortunately, when you try to walk the 
above OID, you get back about 51 variables for each 
instance number. I pressed the marconi guy for more info
but didn't get a response back. When I tried to walk the
marconi mibs with getif each time it tried to load 
fore-common.mib it would gpf. :(

If you've got some time to kill, start snmpwalk'ing from the
above OID and see you can identify which subvariable corresponds
to PVC in/out cell counters. If you find it, please let me 
(and the rest of the list) know.
