[mrtg] Re: Problems with ATM subinterfaces on IOS 12.0(3)T3

[Mark T. Ganzer]

Hmm... looking at it a little closer, I figured out that TWO interface
indexes are being generated for each ATM sub-interface - one named "atm
subif" and the other "aal5 layer". And the router is only collecting
stats for the "aal5 layer" interface. Here is what snmpwalk shows for
ifDescr and ifInOctets:

interfaces.ifTable.ifEntry.ifDescr.1 = ATM5/0
interfaces.ifTable.ifEntry.ifDescr.7 = ATM5/0-atm layer
interfaces.ifTable.ifEntry.ifDescr.8 = ATM5/0-aal5 layer
interfaces.ifTable.ifEntry.ifDescr.11 = ATM5/0.1-atm subif
interfaces.ifTable.ifEntry.ifDescr.12 = ATM5/0.1-aal5 layer
interfaces.ifTable.ifEntry.ifDescr.13 = ATM5/0.2-atm subif
interfaces.ifTable.ifEntry.ifDescr.14 = ATM5/0.2-aal5 layer
interfaces.ifTable.ifEntry.ifDescr.15 = ATM5/0.3-atm subif
interfaces.ifTable.ifEntry.ifDescr.16 = ATM5/0.3-aal5 layer
interfaces.ifTable.ifEntry.ifDescr.17 = ATM5/0.4-atm subif
interfaces.ifTable.ifEntry.ifDescr.18 = ATM5/0.4-aal5 layer

interfaces.ifTable.ifEntry.ifInOctets.1 = 493767824
interfaces.ifTable.ifEntry.ifInOctets.12 = 214936
interfaces.ifTable.ifEntry.ifInOctets.14 = 2607190605
interfaces.ifTable.ifEntry.ifInOctets.16 = 81604782
interfaces.ifTable.ifEntry.ifInOctets.18 = 2248783018
