Try using 64 bit counters.  I added the following to appropriate parts of the 
config tree to get statistics for 64 bit counters

OID    ifHCInOctets           1.3.6.1.2.1.31.1.1.1.6
OID    ifHCInUcastPkts        1.3.6.1.2.1.31.1.1.1.7
OID    ifHCOutOctets          1.3.6.1.2.1.31.1.1.1.10
OID    ifHCOutUcastPkts       1.3.6.1.2.1.31.1.1.1.11

dataSource  ifHCInOctets
    ds-source        =   snmp://%snmp%/ifHCInOctets.%inst%

dataSource  ifHCOutOctets
    ds-source        =   snmp://%snmp%/ifHCOutOctets.%inst%

graph   ifHCInOctets
    color       =   dark-green
    draw-as     =   AREA
    legend      =   "Average bits in"
    y-axis      =   "bits per second"
    units       =   "bits/sec"
    scale       =   8,*
    bytes       =   true

graph   ifHCOutOctets
    color       =   blue
    legend      =   "Average bits out"
    y-axis      =   "bits per second"
    units       =   "bits/sec"
    scale       =   8,*
    bytes       =   true

targetType  switch-port64
  ds = "ifHCInOctets, ifHCOutOctets"
  view = "HC_Octets"

view  HC_Octets
  elements = "ifHCInOctets,ifHCOutOctets"
