Variable is:
============

writeNet     OBJECT IDENTIFIER ::= { lsystem 55 }

writeNet OBJECT-TYPE
  SYNTAX       DisplayString
  ACCESS       write-only
  STATUS       mandatory
  DESCRIPTION  "Write configuration to host using TFTP."
::= { lsystem 55 }

Usage:
======

Set variable 'writeNet.ip_address_of_tftp_server' to value 'tftpfile',
where tftpfile is file name into which the config will be saved. Keep
in mind that, depending on tftp server you are using, it may be required
that specified file already exist, with mode 0666 (on unix). It may be
different on your system, but on Solaris it is so.

In perl, with cmu snmp package, it would be:

# begin

$session = new SNMP::Session
               (
                   DestHost  => "$Router_IP_Address"
                   Community => "public",
                   Timeout   => 10000,
                   Retries   => 3
               );
 
$session->set( 'writeNet.192.168.1.1', "router-confg" );

# end


Hope this helps.
