SNMP::Info::Layer2::Orinoco - SNMP Interface to Orinoco Series Access Points

=head1 AUTHOR

=head1 SYNOPSIS

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

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

=head1 DESCRIPTION

Provides abstraction to the configuration information obtainable from
Orinoco Access Point through SNMP.  Orinoco devices have been manufactured
by Proxim, Agere, and Lucent.

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

 my $orinoco = new SNMP::Info::Layer2::Orinoco(...);
