Hi all,
I still have not heard from anyone, but if you do get a chance to look into
this and reply, it would be appreciated.
If I get a chance to figure it out, I'll post a reply. Thanks,

Subject: Question about Net-SNMP IF-MIB on HP-UX 11.31
Hi all,
I am in HP-UX Support and occasionally we get asked "Why doesn't the HP-UX
Emanate" SNMP Agent do XXXX? Often, the Network Managers are looking for Host
Resources data and we provide them with a link to the Net-SNMP "Internet
Express" download site of the Build that HP updates on a fairly regular basis.
https://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPUXIEXP1131
A few months back, one of our customers asked why Emanate didn't return
ifXtable data. We checked with the Emanate Agent Engineer, and they said, the
Agent supplied with the OpenView Network Node Manager provides it, (extra money
for customer). But the base Emanate Agent supplied with the OS does not.
Submitted enhancement request, which is gathering dust. This week another
customer asked a similar question, which was why weren't we reporting the 10Gig
Interface speed correctly when he looks at an HPUX Agent with SolarWinds.
I checked the latest Net-SNMP 5.7.2 from the HP Download site, and it does not
return ifXtable data in IF-MIB either. A walk agains ifSpeed on Emanate and on
Net-SNMP is the same:
IF-MIB::ifSpeed.1 = Gauge32: 1000000000
IF-MIB::ifSpeed.2 = Gauge32: 1000000000
IF-MIB::ifSpeed.3 = Gauge32: 1000000000
IF-MIB::ifSpeed.4 = Gauge32: 1000000000
IF-MIB::ifSpeed.5 = Gauge32: 4294967295 << This appears by design / see below
IF-MIB::ifSpeed.6 = Gauge32: 4294967295 <<
IF-MIB::ifSpeed.7 = Gauge32: 1000000000
IF-MIB::ifSpeed.8 = Gauge32: 1000000000
IF-MIB::ifSpeed.9 = Gauge32: 1000000000
crete # snmpbulkwalk -v 2c -c public -Cc -t 10 crete:163 ifHighSpeed
IF-MIB::ifHighSpeed = No Such Object available on this agent at this OID
crete # snmpbulkwalk -v 2c -c public -Cc -t 10 crete:161 ifHighSpeed
IF-MIB::ifHighSpeed = No Such Object available on this agent at this OID
Given a tip while investing this issue, I looked in the Net-SNMP and found this
file: /opt/iexpress/net-snmp/share/snmp/mibs/ IF-MIB.txt
ifSpeed OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An estimate of the interface's current bandwidth in bits
per second. For interfaces which do not vary in bandwidth
or for those where no accurate estimation can be made, this
object should contain the nominal bandwidth. If the
bandwidth of the interface is greater than the maximum value
reportable by this object then this object should report its
maximum value (4,294,967,295) and ifHighSpeed must be used
to report the interace's speed. For a sub-layer which has
no concept of bandwidth, this object should be zero."
::= { ifEntry 5 }
ifHighSpeed OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An estimate of the interface's current bandwidth in units
of 1,000,000 bits per second. If this object reports a
value of `n' then the speed of the interface is somewhere in
the range of `n-500,000' to `n+499,999'. For interfaces
which do not vary in bandwidth or for those where no
accurate estimation can be made, this object should contain
the nominal bandwidth. For a sub-layer which has no concept
of bandwidth, this object should be zero."

I have not opened up the source to go through it. Being a support guy, it
appears a daunting task to research completely on my own, and I figured to ask
you guys for help.
Can you please help me understand how Net-SNMP gets IF-MIB data on HP-UX, and
offer any suggestions or clues on how to get the ifXtable data populated in the
IF-MIB on HP-UX Systems???
Thank you VERY much for your help,
