[mrtg] smc 8024L2 - not reporting bandwidth

Hi,

I have been using MRTG with Cisco routers and switches and a few other 
devices quite successfully. I now
need to monitor bandwidth on an SMC 8024L2 (24 port switch) and setup 
the snmp stuff. MRTG picks up
zero for the bandwidth readings. I use snmpwalk and get a reading but it 
looks quite different from when I get
a reading on a Cisco 2900 switch:

Cisco 2900 switch:

--snip--
IF-MIB::ifInOctets.1 = Counter32: 674501832
IF-MIB::ifInOctets.2 = Counter32: 2063832838
IF-MIB::ifInOctets.3 = Counter32: 3582302010
IF-MIB::ifInOctets.4 = Counter32: 2573226198
IF-MIB::ifInOctets.5 = Counter32: 3696566918
--snip--
--snip--
IF-MIB::ifOutOctets.1 = Counter32: 2541476278
IF-MIB::ifOutOctets.2 = Counter32: 3982672916
IF-MIB::ifOutOctets.3 = Counter32: 3760310350
IF-MIB::ifOutOctets.4 = Counter32: 1865532865
IF-MIB::ifOutOctets.5 = Counter32: 986387252
--snip--

SMC 8024L2

--snip--
IF-MIB::ifInOctets.101 = Counter32: 0
IF-MIB::ifInOctets.102 = Counter32: 0
IF-MIB::ifInOctets.103 = Counter32: 0
IF-MIB::ifInOctets.104 = Counter32: 0
IF-MIB::ifInOctets.105 = Counter32: 0
--snip--
--snip--
IF-MIB::ifOutOctets.101 = Counter32: 0
IF-MIB::ifOutOctets.102 = Counter32: 0
IF-MIB::ifOutOctets.103 = Counter32: 0
IF-MIB::ifOutOctets.104 = Counter32: 0
IF-MIB::ifOutOctets.105 = Counter32: 0
--snip--

But it does have bandwidth here:

SNMPv2-SMI::mib-2.16.1.1.1.5.101 = Counter32: 1603554
SNMPv2-SMI::mib-2.16.1.1.1.5.102 = Counter32: 802290
SNMPv2-SMI::mib-2.16.1.1.1.5.103 = Counter32: 108779
SNMPv2-SMI::mib-2.16.1.1.1.5.104 = Counter32: 883371

and here:

SNMPv2-SMI::mib-2.16.1.1.1.9.101 = Counter32: 1616382
SNMPv2-SMI::mib-2.16.1.1.1.9.102 = Counter32: 790433
SNMPv2-SMI::mib-2.16.1.1.1.9.103 = Counter32: 99653
SNMPv2-SMI::mib-2.16.1.1.1.9.104 = Counter32: 891584

I guess the question is:

How do I get MRTG to track it?

Thank you in advance,
Randy Katz
