# Let SNMP::Info determine the correct subclass for you.
my $info = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myrouter',
Community => 'public',
Version => 2
)

=head1 DESCRIPTION
This class provides access to Aggregated Links configuration on devices
supporting C<ifStackTable>.
Use or create in a subclass of SNMP::Info. Do not use directly.
