=head1 NAME
SNMP::Info::IEEE802dot11 - SNMP Interface to data from F<IEEE802dot11-MIB>
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
my $dot11 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $dot11->class();
print " Using device sub class : $class\n";
=head1 DESCRIPTION
SNMP::Info::IEEE802dot11 is a subclass of SNMP::Info that provides an
interface to F<IEEE802dot11-MIB>. This MIB is used in standards based
802.11 wireless devices.
Use or create a subclass of SNMP::Info that inherits this one.
Do not use directly.
=head2 Inherited Classes
=over
None.

=head2 Required MIBs
=over
=item F<IEEE802dot11-MIB>
=back
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $dot11->vendor()
Tries to discover the vendor from dot11_man_name() - returns lower case
of the first word in the first instance found.
=item $dot11->model()
Tries to discover the model from dot11_prod_name() - returns lower case
of the first instance found.
=item $dot11->os_ver()
Tries to discover the operating system version from dot11_prod_ver() - returns
string of numeric and decimals in the first instance found.
=back
=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=over
=item $dot11->i_ssidlist()
Returns reference to hash. SSID's recognized by the radio interface.
(C<dot11DesiredSSID>)
=item $dot11->i_80211channel()
Returns reference to hash. Current operating frequency channel of the radio
interface.
=item $dot11->dot11_cur_tx_pwr_mw()
Returns reference to hash. Current transmit power, in milliwatts, of the
radio interface.
