This article explains how to configure the Dell
PowerConnect
5316M Gigabit Ethernet
switch, which resides within the Dell Modular Server Enclosure, to interoperate and
connect with Cisco IOS-based and CatOS-based switches by using industry-standard
link aggregation groups that adhere to the IEEE 802.3ad standard.
