The SNMP protocol works with numeric OIDs for example
.1.3.6.1.2.1.1.3.0
These numbers are like an IP address and point to a specific point in the SNMPdatabase so that you can retrieve the value stored there. Like an IP address, this sequence of numbers does not make any sense to a human. This is where a MIB file fits in:
it allows you to convert the numeric string to a text representation.
snmptranslate is a tool included in
net-snmp which allows you convert between numeric and text OIDs. In our example above this translates to system uptime.
#snmptranslate .1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance
or in reverse
#snmptranslate -On DISMAN-EVENT-MIB::sysUpTimeInstance
.1.3.6.1.2.1.1.3.0
where -On is output the OID numerically.
Most of the time however we are interested in taking a vendor provided MIB and working out what OIDs we can poll. For this example I'm using snmptranslate v5.7.1 installed on
FreeBSD 9 and I will be interrogating the Opengear MIBs which are available on their
FTP server.
Lets pick the
OG-STATUS-MIB.mib. Download this MIB into a folder and then run snmptranslate as follows:
snmptranslate -m /home/myuser/opengear/OG-STATUS-MIB.mib -Tp
MIB search path: /home/myuser/.snmp/mibs:/usr/local/share/snmp/mibs
Cannot find module (OPENGEAR-SMI-MIB): At line 12 in /home/myuser/opengear/OG-STATUS-MIB.mib
Did not find 'opengear' in module #-1 (/home/myuser/opengear/OG-STATUS-MIB.mib)
Unlinked OID in OG-STATUS-MIB: ogStatus ::= { opengear 16 }
Undefined identifier: opengear near line 24 of /home/myuser/opengear/OG-STATUS-MIB.mib
Cannot adopt OID in OG-STATUS-MIB: ogStatusGroups ::= { ogStatusConformance 2 }
Cannot adopt OID in OG-STATUS-MIB: ogStatusCompliances ::= { ogStatusConformance 1 }
Cannot adopt OID in OG-STATUS-MIB: ogStatusCompliance ::= { ogStatusCompliances 1 }
Where -m is the path to the downloaded mib, -Tp prints in tree format. The error marked in red above shows that we are missing a module which is defined on line 12 of OG-STATUS-MIB.mib.
#cat OG-STATUS-MIB.mib |more

If you look at line 12 (marked in blue above) it says you need the OPENGEAR-SMI-MIB which can be found on the opengear ftp site too:
OG-SMI-MIB.mib. Download this file and then run snmptranslate again to view the tree. Note the order of the files as presented to the -m option is important otherwise snmptranslate does not work correctly.
