=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
|
|

=head1 DESCRIPTION
|
|
|
|
Provides interface to SNMP Data available on newer Aironet devices running 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.
