Hi Pavel,

Working with SNMP v1 or v2c both return counter32 values :

[gardais at br40st11 ~]$ snmpget -c public -v 1 res0-foundry1 ifOutOctets.513
IF-MIB::ifOutOctets.513 = Counter32: 1398061606
[gardais at br40st11 ~]$ snmpget -c public -v 2c res0-foundry1 ifOutOctets.513
IF-MIB::ifOutOctets.513 = Counter32: 1398282706

Is this an MRTG internal cooking ?
