Dear net-snmp-coders,
Thanks for your replies.
RS>You created a new implementation, right? No copying of the existing
code?
Yes, I created a new implementation using mib2c.mfd.conf, not copying of
the agent/mibgroup/if-mib.
RS>So what flags *are* you using?
The only flag I am using is NETSNMP_CACHE_DONT_INVALIDATE_ON_SET, which is
the default by the generated template.
It seems there is a timing issue in subagent triggering the cache reload,
because "OID not increasing" occasionally happened at the first query(e.g.
snmpwalk), but if I issue another snmpwalk it populates everything okay.
Most of the time, the ifTable subagent works just fine.

So what flags *are* you using?

Depending on the flags set, you may need to free the cache before trying to
reload it. Of course, if you know what interface was added/removed, you
could
add/remove it directly to the container instead of reloading the cache.

Also note that ifIndexes should not get renumbered as rows are
inserted/deleted.
