+=head1 DESCRIPTION
+
+This class provides access to Aggregated Links configuration on Cisco devices.
+It combines Cisco PAgP and IEEE 802.3ad information.
+
+Use or create in a subclass of SNMP::Info.  Do not use directly.

+
+Returns a HASH reference mapping from slave to master port for each member of

+ifIndex of the corresponding master ports.
+
+=item C<agg_ports_pagp>
+
+Implements the PAgP LAG info retrieval. Merged into C<agg_ports> data
+automatically.
