=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $aironet = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
DestHost => 'myswitch',
|
|
Community => 'public',

Version => 2

)

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

|
|
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.

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
|
|
|

|
|
|
|
=item $aironet->awc_duplex()
|
|
|
|
Gives the admin duplex setting for the Ethernet Port.
|
|
|
|
B<awcEtherDuplex.0>
|
|
|
|
=item $aironet->mac()
|
|
|

Gives the MAC Address of the wireless side

=head1 TABLE ENTRIES
|
|
|
|
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''.
