Hi Alan,
Thank you for the clarification.
I am working in enterprise-1 and hence defined private mib for their products
with iso.3.6.1.4.1.PEN1.1
and now the enterprise-1 has bee
iso.3.6.1.4.1 signifies an enterprise. The next number is the Private
Enterprise Number (PEN), anything after that is up to the enterprise to define
the meaning of.
So yes and no (but mostly no !). If the first enterprise number (PEN) belongs
to your organization (ie. you work for
If you control the MIB structure would it work for you to structure your MIB to
contain tables ? ie. when you read, say, CPU usage you will read a CPU usage
table with an entry for each machine - one MIB, one agent, multiple entries.

Maybe you could wrap the snmptrap executable in a shell script.
ie. Make a shell script called snmptrap that reads in the commandline variables
and then calls the “real” snmptrap with the additional port information added.
Put the snmptrap shell script somewhere in the path ahead of the real
or in the packet.

Hi ,
Adding to previous mail,
I found one difference between agentxtrap and snmptrap. agentxtrap can
Snmpd will respond to snmp requests for the MIB variables it understands. But
if you add new software that has a MIB of its own, snmpd cannot respond because
it has no knowledge of the new software or its internal state. Someone can
write an snmp subagent that will respond to requests about the
This will probably answer many of your questions:

You should also look into a pass script:
How come your subagent can’t wait for a request to come in from the manager and
check the file at that time ? For example, if the file contains data upon which
the response is based, subagent waits for the poll, then opens the file,
calculates and sends the response.
Or are you trying to keep

you please give an example. Are you using the command line snmpget tool ?

I have had a little experience building subagents with mib2c.
mib2c will provide a skeleton of an agent/subagent and it's up to the developer
to fill in the implementation-specific details (from your example, mib2c will
make a stub function for you to fill in with a real implementation of a

They can help associate notifications that indicate alarm conditions with
notifications that indicate that the same alarm has cleared.
In the normal run of events, the MIB text file is the only way one would learn
what notifications are supported without reading the source code since walking
Hi Janki
Did MIB2C also create any files for you that ended with the words: …_data_get.c
or …_data_access.c ?
I ask because when I ran MIB2C it generated these files to give me an
opportunity to write functions that would be called when the SNMP agent wanted
to fetch a value to return to the

I have them on the network manager so that I can refer to OIDs by name instead
of just the numbers. And I used them on the network device when I compiled an
SNMP subagent using “MIB for DUMMIES”. But in truth you don’t need a MIB file
anywhere, you can just refer to objects by their numeric ID.
The Management Information Base (MIB) will be hard coded into the program
running on the network device (The SNMP agent). This SNMP agent can use any
technique it likes to store its information (for example, my snmp agent stores
all its information in mysql).

This seems like such a basic thing, so I apologize if I've missed a previous

I've successfully implemented a subagent for my custom MIB. I can snmpwalk it
