Hi and thanks for the response,
Since it is not possible to add our own rows to the ifTable right now and we
don't know when this feature can be added to the net-snmp, I think it should
be nice and helpful to know the way to disable/exclude ifTable on net-snmp
and do everything in our subagent?
Thanks,
/Masoud

There is no need to clobber the entire ifTable. Simply register a row
for each port. You'll need to register each object in each row
individually, which is a bit of a pain, but that's the only real problem. I
don't know if there are helpers for this. I would recommend using very
large numbers for your ifIndex to keep clear of those generated by the MIB
module.
Hopefully, the ifTable implementation has a way to cooperatively add your
own rows, but I've never examined it. Anyone?
Thanks,
Mike
