2.1 LINK AGGREGATION
Link Aggregation is a method of grouping multiple physical ports on a network device into one
logical link according to the IEEE 802.3ad-2002 standard. Because Link Aggregation is standards
based, it allows for automatic configuration with manual overrides (if applicable), and can operate
on 10 Mbps, 100 Mbps, or 1000 Mbps Ethernet full duplex ports. Thus the network administrator
can combine a group of five 100 Mbps ports into a logical link (trunk) that functions as a single
500 Mbps port. As long as the DFE modules agree on which ports are in the trunk, there are no
problems with looping, and the Spanning Tree can treat this trunk as a single port.
