=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $c4000 = new SNMP::Info(
                        AutoSpecify => 1,
                        Debug       => 1,
                        # These arguments are passed directly to SNMP::Session
                        DestHost    => 'myswitch',
                        Community   => 'public',
                        Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

 my $class      = $c4000->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

Abstraction subclass for Cisco Catalyst 4000 Layer 2/3 Switches.  

For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above. 

 my $c4000 = new SNMP::Info::Layer3::C4000(...);
