SYNOPSIS

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

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