As far as I know, we can not distinguish whether the snmpgetnext request
received is from snmpwalk executable or snmpgetnext itself.
Regarding the example you mentioned, why do you want to gather all the
instances of the table in the 1st getnext itself when snmpwalk is
given.?
Ideally the agent/application owning the table should give the current
OID objects/instances available. So, when the agent/application receives
the getnext request, irrespective of whether it is part of snmpwalk, the
application should return the next OID instance that is currently
exists.

Suresh.

Thanks.
I do know the way how snmpwalk works.
Let me explain my requir. in detail.
For snmpgetnext request i have to do some operation for xx OID.
For snmpwalk request , i have to do the same operation plus some
other
functionality for xx OID.
Eg :
snmpwalk of xx table :
we gather all the instance of xx table data for the 1st getnext
req. itself.
while walk is going on , there is a chance an instance may get
deleted/added thro' other appln( other than snmp) .which will result in
displaying of ambiguous data.
In this case how to diff. walk & getnext.
Thanks

Hi Valantina,
Snmpwalk is nothing but a series of snmpgetnext requests.
For the given OID, snmpwalk first sends an snmpgetnext request. After
receiving the response for the getnext, it retrieves the OID from the
response and then sends snmpgetnext request on this OID. This way
snmpgetnext requests are sent until all OIDs/variables in the subtree
(and their values) below the given OID are retrieved.
Please see the man page of snmpwalk.

Suresh.

Hi all,
Is there a way to differentiate the request from snmpwalk &

Like a flag in request structure which diff. walk & getnext..
I have surfed the net-snmp , but i couldn't find out a way.
Thanks
Valantina
