=head1 SYNOPSIS

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

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

=head1 DESCRIPTION

Provides abstraction to the configuration information obtainable from a 
Asante device through SNMP.

=item $asante->os()

Returns 'asante'

=item $asante->os_ver()

Culls software version from description()

Cross references $asante->id() to the F<ASANTE-HUB1012-MIB> and returns
the results.

=item $asante->interfaces()

Returns reference to the map between IID and physical Port.

=item $asante->i_description() 

Description of the interface.

=item $asante->i_mac()

anything connected to it.

=item $asante->i_name()

Returns reference to map of IIDs to human-set port name.
