SNMP::Info::Layer3::Scalance - SNMP Interface to Siemens Scalance Switches
=head1 AUTHOR
Christoph Handel
=head1 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";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
Siemens Scalance Switch via SNMP.
Tested only with sclance xr524

=head1 Change Log
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $scalance->layers()
Overwrite snmp value, we support 1-3
=item $scalance->os()
Returns scalance
=item $scalance->vendor()
Returns siemens
=item $scalance->model()
extrace a meaningful name from description
=item $scalance->mac()
use the dot1dBaseBridgeAddress
=item $scalance->os_ver()
clean up os_version string
=item $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
=item $scalance->lldp_ip()
simatic does not implement lldpRemManAddrIfSubtype
but remote system names are available
try to resolve them via DNS and use that

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.

Returns reference to hash of ports to remote ips.
