=head1 NAME
SNMP::Info::Layer3::Aironet - Perl5 Interface to Cisco Aironet Wireless
Devices running Aironet software, not IOS
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $aironet = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $aironet->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=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.
my $aironet = new SNMP::Info::Layer3::Aironet(...);
=head2 Inherited Classes
=over
=item SNMP::Info::Layer3
=back
=head2 Required MIBs
=over
=item F<AWCVX-MIB>
=item F<IEEE802dot11-MIB>
=back
These MIBs are now included in the v2.tar.gz archive available from
ftp.cisco.com. Make sure you have a current version.
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $aironet->awc_duplex()
Gives the admin duplex setting for the Ethernet Port.
C<awcEtherDuplex.0>
=item $aironet->mac()
Gives the MAC Address of the wireless side
C<dot11StationID.2>
=item $aironet->os()
'aironet'
=item $aironet->os_ver
Tries to cull the version from the description field.
=item $aironet->vendor()
Returns 'cisco'.
=back
=head2 Globals imported from SNMP::Info::Layer3
See documentation in L<SNMP::Info::Layer3/"GLOBALS"> for details.
=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=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''.
=back
=head2 Aironet specific items
=over
=item $aironet->awc_default_mac()
Gives the default MAC address of each interface.
C<awcIfDefaultPhyAddress>
=item $aironet->awc_mac()
Gives the actual MAC address of each interface.
C<awcIfPhyAddress>
=item $aironet->awc_ip()
Gives the IP Address assigned to each interface.
C<awcIfIpAddress>
=item $aironet->awc_netmask()
Gives the NetMask for each interface.
C<awcIfIpNetMask>
=item $aironet->awc_msdu()
C<awcIfMSDUMaxLength>
=back
=head2 Table Methods imported from SNMP::Info::Layer3
