Description Zhiyong Wu 2008-06-23 10:11:23 EDT
Description of problem:

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


ipSystemStatsInOctets Object Information
Object Name 	ipSystemStatsInOctets
Full OID
Full Path 
MAX-Access 	ReadOnly

[root@IPV6testee Desktop]# snmpwalk -v2c -c public
udp6:[3ffe:501:ffff:100::10]:161 .
IP-MIB::ipSystemStatsInOctets = No Such Instance currently exists at this OID


Object Name 	ipSystemStatsOutOctets
Full OID
Full Path 
MAX-Access 	ReadOnly

[root@IPV6testee Desktop]# snmpwalk -v2c -c public
udp6:[3ffe:501:ffff:100::10]:161 .
IP-MIB::ipSystemStatsOutOctets = No Such Instance currently exists at this OID


Object Name 	ipNetToPhysicalLastUpdated
Full OID

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

Comment 1 Jan Safranek 2008-06-23 11:00:55 EDT
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:

> ipNetToPhysicalLastUpdated is the only one which could be computed by

> quite often to get exact value or have the value with ± few
> (dozens?) seconds precision, which is pretty useless for this kind of
> table. So I have decided not to implement it for now.

For a complete list what's missing in RHEL 5.2, you can look at
http://intranet.corp.redhat.com/ic/intranet/IPv6IPMIB.html - 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.
