SNMP::Info::CiscoConfig - SNMP Interface to Cisco Configuration Files

=head1 AUTHOR

Justin Hunter, Eric Miller

=head1 SYNOPSIS

    my $ciscoconfig = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 

    or die "Can't connect to DestHost.\n";

    print " Using device sub class : $class\n";

=head1 DESCRIPTION

SNMP::Info::CiscoConfig is a subclass of SNMP::Info that provides an interface
to F<CISCO-CONFIG-COPY-MIB>, F<CISCO-FLASH-MIB>, and F<OLD-CISCO-SYS-MIB>.
These MIBs facilitate the writing of configuration files.

Use or create a subclass of SNMP::Info that inherits this one.
Do not use directly.

These are methods that provide SNMP set functionality for overridden methods
or provide a simpler interface to complex set operations.  See
L<SNMP::Info/"SETTING DATA VIA SNMP"> for general information on set
operations. 

=over

=item $ciscoconfig->copy_run_tftp (tftpserver, tftpfilename )

Store the running configuration on a TFTP server.  Equivalent to the CLI
commands "copy running-config tftp" or "write net".

This method attempts to use newer "copy running-config tftp" procedure first
and then the older "write net" procedure if that fails.  The newer procedure
is supported Cisco devices with the F<CISCO-CONFIG-COPY-MIB> available, Cisco
IOS software release 12.0 or on some devices as early as release 11.2P.  The
older procedure has been depreciated by Cisco and is utilized only to support
devices running older code revisions.

 Example:
 $ciscoconfig->copy_run_tftp('1.2.3.4', 'myconfig') 
    or die "Couldn't save config. ",$ciscoconfig->error(1);

=item $ciscoconfig->copy_run_start()

Copy the running configuration to the start up configuration.  Equivalent to
the CLI command C<"copy running-config startup-config"> or C<"write mem">.

This method attempts to use newer C<"copy running-config startup-config">
procedure first and then the older C<"write mem"> procedure if that fails.
The newer procedure is supported Cisco devices with the
F<CISCO-CONFIG-COPY-MIB> available, Cisco IOS software release 12.0 or on
some devices as early as release 11.2P.  The older procedure has been
depreciated by Cisco and is utilized only to support devices running older
code revisions.

 Example:
 $ciscoconfig->copy_run_start()
    or die "Couldn't save config. ",$ciscoconfig->error(1);
