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
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 & snmpgetnext ?

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
