=head1 NAME
SNMP::Info::Layer2::NAP222x - SNMP Interface to Nortel 2220 Series Access
Points
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $nap222x = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $nap222x->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a Nortel
2220 series wireless Access Points through SNMP.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $nap222x->interfaces()
Returns reference to map of IIDs to physical ports.
=item $nap222x->i_duplex()
Returns reference to hash. Maps port operational duplexes to IIDs.
(C<ntWlanPortSpeedDpxStatus>)
=item $nap222x->i_duplex_admin()
Returns reference to hash. Maps port admin duplexes to IIDs.
(C<ntWlanPortCapabilities>)
=item $nap222x->i_name()
Returns a human name based upon port description.
=item $nap222x->bp_index()
Returns a mapping between C<ifIndex> and the Bridge Table. This does not
exist in the MIB and bridge port index is not the same as C<ifIndex> so it is
created.
=item $nap222x->i_ssidlist()
Returns reference to hash. SSID's recognized by the radio interface.
=item $nap222x->i_ssidbcast()
Returns reference to hash. Indicates whether the SSID is broadcast.
=item $nap222x->i_80211channel()
Returns reference to hash. Current operating frequency channel of the radio
interface.
=item $nap222x->i_vlan()
The default Vlan ID of the radio interfaces.
