SNMP 2c with 64 bit works on one host, and not in another

[laedrus]

Hello there,

i'm having this issue, i configured a host as a mirror for the other machines i will poll.

now that i get it configured, i can poll 64 bits as well 32:

[root@darkstar ~]# snmpget -c mycomm -v 2c localhost .1.3.6.1.2.1.31.1.1.1.6.3
IF-MIB::ifHCInOctets.3 = Counter64: 1289148815

[root@darkstar ~]# snmpget -c mycomm -v 2c localhost .1.3.6.1.2.1.2.2.1.16.3
IF-MIB::ifOutOctets.3 = Counter32: 1139264416


but on another host, i JUST COPIED THE CONF FILE (any problem doing that? i don't think so)


and here's what i got:

[root@darkstar user]# snmpget -c mycomm -v 2c localhost .1.3.6.1.2.1.2.2.1.16.3
IF-MIB::ifOutOctets.3 = Counter32: 3810332526


[root@darkstar user]# snmpget -c mycomm -v 2c localhost .1.3.6.1.2.1.31.1.1.1.6.3
IF-MIB::ifHCInOctets.3 = No Such Object available on this agent at this OID


The only thing i can suppose is that the OID's of SNMP are bound with the hardware in a way that is unknown to me.

is that true? the only difference between the 2 hosts is it's hardware.

they have the same version of the same distribution installed.

Please omit the last tupel ".3" on your snmpget statement or use snmpwalk and retry

The asnwer changes from this

IF-MIB::ifHCInOctets.3 = No Such Object available on this agent at this OID

to this

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

ok, but i got one thing:

the host that works is Fedora 7 and have net-snmp-5.4

the one that not works is CentOS 4.4 and have net-snmp-5.1

could be this??

[gandalf]

I've not used 5.1 since ages. And please remember that HC counters are NOT mandatory. If omitting .3 (the interface index; it may vary from target to target) does not show anything, I bet that HC counter support is not implemented for that target

[laedrus]

so, the problem is my hardware? or i can solve this by software?

remember, the host that works (with the very same query) is fedora 7 with NET-SNMP 5.4

and the one that doesn't works is CentOS 4 with NET-SNMP 5.1

by the way, what means HC ??

and what you means with target? the interface or the host?

thanks

[gandalf]

by the way, what means HC ??

High Counters aka 64bit counters

and what you means with target? the interface or the host?

the target host (remote host)

[laedrus]

just to be sure, i'm testing from localhost to localhost

any ideas?

could net-snmp implement HC counters on version 5.4 and not in the 5.1?

do you wanna see the conf file?

[gandalf]

That's a net-snmp question. And it will depend how the net-snmp package was built. Find some help at the first link of my sig, else post to net-snmp mailing list to get an authoritative answer
