Andreas,
Gabriel's question reminded me of a puzzle I tried to solve once, but left on the side and moved on to other projects. I have been using mrtg to monitor an ASX-1000 switch for some time. I was unable to graph traffic for individual PVCs. After walking the MIB on the switch I came to the conclusion that there are not OIDs for individual PVCs. Please correct me if I'm wrong.
A kind soul on the list gave me good pointers. I used GetIf, and Solar Winds MibWalk utility to walk the MIB. There I could see OIDs for the atm ports. Specifically I was trying to graph traffic in/out of port 2D1. I saw that the index number for port 2D1 was 1033. Walking the tree I noticed the following:
interfaces.ifTable.ifEntry.ifDescr.1029 : Atm Interface
interfaces.ifTable.ifEntry.ifDescr.1031 : SONET Medium/Section/Line
interfaces.ifTable.ifEntry.ifDescr.1032 : SONET Path
interfaces.ifTable.ifEntry.ifDescr.1033 : Atm Interface
interfaces.ifTable.ifEntry.ifDescr.1034 : Atm Interface
interfaces.ifTable.ifEntry.ifDescr.1035 : Atm Interface
interfaces.ifTable.ifEntry.ifDescr.1036 : Atm Interface
interfaces.ifTable.ifEntry.ifDescr.1042 : Atm Interface
I assumed that 1031 and 1032 were the two PVCs on port 2D1. However there was no OID for ifInOctets and ifOutOctets for them. My conclusion was that there are no OIDs for individual PVCs, therefore it's not possible to monitor traffic in/out for them. What is your experience this. Do you have any suggestions/input.
TIA
- Ivette
On the MIB tree there were OIDs for 1031

Hi,
I have here an ASX200 running. I have done a snmpwalk and I got all the information about inOctets and outOctets from MIB2 based on the ifindex.

You also can try to use the ATM mib. But normaly you get the info from MIB2.
I hope this helps.
