=head1 NAME
SNMP::Info::Layer3::Aironet - Perl5 Interface to Cisco Aironet Wireless Devices
=head1 DESCRIPTION
Inherits all methods from SNMP::Info::Layer3
=head1 AUTHOR
Max Baker (C<max@warped.org>)
=head1 SYNOPSIS
my $aironet = new SNMP::Info::Layer3::Aironet(DestHost => 'myswitch',
Community => 'public');
my $mac = $aironet->mac();
=head1 CREATING AN OBJECT
=over
=item new SNMP::Info::Layer3::Aironet()
Arguments passed to new() are passed on to SNMP::Session::new()
my $aironet = new SNMP::Info::Layer3::Aironet(
DestHost => $host,
Community => 'public',
Version => 3,...
)
die "Couldn't connect.\n" unless defined $aironet;
=item $aironet->session()
Sets or returns the SNMP::Session object
# Get
my $sess = $aironet->session();
# Set
my $newsession = new SNMP::Session(...);
$aironet->session($newsession);
=back
=head1 Globals
=over
=item $aironet->mac()
Gives the MAC Address of the wireless side
B<dot11StationID.2>
=item $aironet->awc_duplex()
Gives the admin duplex setting for the Ethernet Port.
B<awcEtherDuplex.0>
=item $aironet->vendor()
Returns 'cisco'.
=back
=head1 TABLE ENTRIES
=head2 Aironet specific items
=over
=item $aironet->awc_default_mac()
Gives the default MAC address of each interface.
B<awcIfDefaultPhyAddress>
=item $aironet->awc_mac()
Gives the actual MAC address of each interface.
B<awcIfPhyAddress>
=item $aironet->awc_ip()
Gives the IP Address assigned to each interface.
B<awcIfIpAddress>
=item $aironet->awc_netmask()
Gives the NetMask for each interface.
B<awcIfIpNetMask>
=item $aironet->awc_msdu()
B<awcIfMSDUMaxLength>
=back
=head2 Overrides
=over
=item $aironet->bp_index()
Takes the bp_index() value from SNMP::Info::Bridge and overrides the wireless port
to be assigned to the transparent bridge port (port 0)
=item $aironet->fw_mac()
Adds static table entries from bs_mac() to port 0 so that wireless MAC addresses will
be reported. Forwarding table entries for port 0 are removed.
=item $aironet->fw_port()
Adds the static table port mappings to the forwarding table port mappings by adding
bs_port() to fw_port()
=item $aironet->i_duplex()
Adds the value of awc_duplex() to each Ethernet port seen.
=item $aironet->i_mac()
Overrides the values for i_mac with the value from awc_mac() if they are set.
=item $aironet->i_ignore()
Ignores ports that are of type ``rptr'' and ``lo''.
