Inaccurate snmp reports on DU 3.2g

Greetings,

I've recently begun using the excellent MRTG package to monitor
network traffic on our Digital Unix servers (Alpha 2100s running DU
3.2g) and have run into a problem. snmpd on these boxes is not
reporting interface speeds correctly.

Here is an excerpt from an snmpwalk of the interfaces variables on
one the boxes in question:

interfaces.ifNumber.0 = 4
interfaces.ifTable.ifEntry.ifDescr.1 = "tu DEC TULIP Ethernet Interface"
interfaces.ifTable.ifEntry.ifDescr.2 = "tu DEC Fast Ethernet Interface"
interfaces.ifTable.ifEntry.ifDescr.3 = "sl Serial Line Interface"
interfaces.ifTable.ifEntry.ifDescr.4 = "lo Local Loopback Interface."
interfaces.ifTable.ifEntry.ifType.1 = ethernet-csmacd(6)
interfaces.ifTable.ifEntry.ifType.2 = ethernet-csmacd(6)
interfaces.ifTable.ifEntry.ifType.3 = 28
interfaces.ifTable.ifEntry.ifType.4 = 24
interfaces.ifTable.ifEntry.ifMtu.1 = 1500
interfaces.ifTable.ifEntry.ifMtu.2 = 1500
interfaces.ifTable.ifEntry.ifMtu.3 = 0
interfaces.ifTable.ifEntry.ifMtu.4 = 0
interfaces.ifTable.ifEntry.ifSpeed.1 = Gauge: 0
interfaces.ifTable.ifEntry.ifSpeed.2 = Gauge: 0
interfaces.ifTable.ifEntry.ifSpeed.3 = Gauge: 0
interfaces.ifTable.ifEntry.ifSpeed.4 = Gauge: 0
interfaces.ifTable.ifEntry.ifAdminStatus.1 = down(2)
interfaces.ifTable.ifEntry.ifAdminStatus.2 = up(1)
interfaces.ifTable.ifEntry.ifAdminStatus.3 = down(2)
interfaces.ifTable.ifEntry.ifAdminStatus.4 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.1 = down(2)
interfaces.ifTable.ifEntry.ifOperStatus.2 = up(1)
interfaces.ifTable.ifEntry.ifOperStatus.3 = down(2)
interfaces.ifTable.ifEntry.ifOperStatus.4 = up(1)
interfaces.ifTable.ifEntry.ifInOctets.1 = 0
interfaces.ifTable.ifEntry.ifInOctets.2 = 2698279047
interfaces.ifTable.ifEntry.ifInOctets.3 = 0
interfaces.ifTable.ifEntry.ifInOctets.4 = 22358189
interfaces.ifTable.ifEntry.ifOutOctets.1 = 0
interfaces.ifTable.ifEntry.ifOutOctets.2 = 757938498
interfaces.ifTable.ifEntry.ifOutOctets.3 = 0
interfaces.ifTable.ifEntry.ifOutOctets.4 = 22358189

The ifSpeed entries are definately incorrect. We have similar boxes
running WindowsNT which report the ifSpeed correctly, and a DexStation
3000 with a LANCE ethernet interface that also reports correctly.

Has anyone seen this before and is there a fix?

thanks,
