SYNOPSIS

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

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

GLOBALS

These are methods that return scalar value from SNMP

$scalance->layers(): Overwrite snmp value, we support 1-3
$scalance->os(): Returns scalance
$scalance->vendor(): Returns siemens
$scalance->model(): extract a meaningful name from description
$scalance->mac(): use the dot1dBaseBridgeAddress
$scalance->os_ver(): clean up os_version string
$scalance->i_description(): siemens returns a description including firmware, switch serial, etc clean it up. Try to use anything past VLAN or Port. And if this fails past the last comma
$scalance->lldp_ip(): simatic does not implement lldpRemManAddrIfSubtype but remote system names are available try to resolve them via DNS and use that
