ifHCInOctets and Red Hat

Hi,

I have a question with regards to Red Hat Enterprise Linux 4 AS Update 2.
During initial installation, it asks whether we want to install netsnmp or
not. The packages installed are

rpm -qa | grep net-snmp

net-snmp-5.1.2-11.EL4.6

net-snmp-libs-5.1.2-11.EL4.6

net-snmp-utils-5.1.2-11.EL4.6

I am able to get info on ifInOctets

IF-MIB::ifInOctets.1 = Counter32: 525914905

IF-MIB::ifInOctets.2 = Counter32: 5194892

However for *ifHCInOctets, (*the famous ifHCInOctets 64 bit counter)
**

I get

snmpwalk -v2c -c public 127.0.0.1 .1.3.6.1.2.1.31.1.1.1.6

IF-MIB::ifHCInOctets = No Such Object available on this agent at this OID

Q1) Does anyone have experience with Red Hat and Net-SNMP ? Are these rpm
packages supposed to read this counter , perhaps I have badly configured
something, perhaps there is a patch for this package ?

Q3) Would I have to get rid of the package and then download version 5.3 and
perform compile from scratch with a --enable -mfd -rewrites ??

Thank you for your time and help,

Cheers,

Malcolm
