Description Zhiyong Wu 2008-06-23 14:11:23 UTC
Description of problem:

  when doing snmpv2c testing, it seems that net-snmp doesnt implement the
following mib oid items:


ipSystemStatsInOctets Object Information

[root@IPV6testee Desktop]# snmpwalk -v2c -c public

ipSystemStatsInOctets, ipSystemStatsOutOctets: I miss necessary support in
kernel (see bug #293041)

ipNetToPhysicalLastUpdated: net-snmp can only guess, when an interface gets
created/changed by periodical polling of all interfaces, therefore it would be
not precise (let's say +/- 15-30 seconds) or it would have impact on performance
 (poll the interfaces often). Therefore we* agreed not to implement it.

*) "we" means me + implementors of ipNetToPhysicalTable, Mitsuru Chinen and/or
Varun Chandramohan@IBM. Here is mail from Varun where we were discussing it:

For a complete list what's missing in RHEL 5.2, you can look at - net-snmp does not
implement everything what has red 'Error' in net-snmp column.

Unless you want me to implement ipNetToPhysicalLastUpdated with low precision,
I'd close this bug.
