=head1 DESCRIPTION
 | 
						|
 | 
						|
SNMP::Info subclass to provide access to SNMP data for an Aironet device
 | 
						|
running Aironet software, not cisco IOS.
 | 
						|
 | 
						|
Note there are two classes for Aironet devices :
 | 
						|
 | 
						|
=over
 | 
						|
 | 
						|
=item SNMP::Info::Layer3::Aironet
 | 
						|
 | 
						|
This class is for devices running Aironet software (older)
 | 
						|
 | 
						|
=item SNMP::Info::Layer2::Aironet
 | 
						|
 | 
						|
This class is for devices running Cisco IOS software (newer)
 | 
						|
 | 
						|
=back
 | 
						|
 | 
						|
For speed or debugging purposes you can call the subclass directly, but not
 | 
						|
after determining a more specific class using the method above.

=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''.
