=head1 NAME
SNMP::Info::Layer3::Aruba - SNMP Interface to Aruba wireless switches
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
my $aruba = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $aruba->class();
print " Using device sub class : $class\n";
=head1 DESCRIPTION
SNMP::Info::Layer3::Aruba is a subclass of SNMP::Info that provides an
interface to Aruba wireless switches. The Aruba platform utilizes
intelligent wireless switches which control thin access points. The thin
access points themselves are unable to be polled for end station information.
This class emulates bridge functionality for the wireless switch. This enables
end station MAC addresses collection and correlation to the thin access point
the end station is using for communication.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.
