SNMP::Info::Layer2::N2270 - SNMP Interface to Nortel 2270 Series Wireless
Switch

=head1 AUTHOR

Eric Miller

=head1 SYNOPSIS

    #Let SNMP::Info determine the correct subclass for you.

    my $n2270 = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 

    or die "Can't connect to DestHost.\n";

    my $class = $n2270->class();
    print " Using device sub class : $class\n";

=head1 DESCRIPTION

Provides abstraction to the configuration information obtainable from a 
Nortel 2270 Series Wireless Switch 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. 

my $n2270 = new SNMP::Info::Layer2::N2270(...);

These are methods that return scalar value from SNMP

=item $n2270->vendor()

Returns 'nortel'

=item $n2270->os()

Returns 'nortel'

=item $n2270->model()

Cross references $bayhub->id() to the F<SYNOPTICS-ROOT-MIB> and returns
the results.

Removes C<sreg-WLANSecuritySwitch> from the model name

=back

=head2 Overrides

=over

=item  $bayhub->index_factor()

Required by SNMP::Info::SONMP.  Number representing the number of ports
reserved per slot within the device MIB.  Returns 256.

=item $bayhub->slot_offset()

Required by SNMP::Info::SONMP.  Offset if slot numbering does not
start at 0.  Returns 0.
