Link Aggregation Groups

This chapter provides the following examples:

•Create Two LAGs on page 55

•Add Ports to LAGs on page 56

•Enable Both LAGs on page 59

Link aggregation allows the switch to treat multiple physical links between two endpoints as a single logical link. All the physical links in a given LAG must operate in full-duplex mode at the same speed. LAGs can be used to directly connect two switches when the traffic between them requires high bandwidth and reliability, or to provide a higher-bandwidth connection to a public network. Management functions treat a LAG as if it were a single physical port. You can include a LAG in a VLAN. You can configure more than one LAG for a given switch.

LAGs offer the following benefits:

•Increased reliability and availability. If one of the physical links in the LAG goes down, traffic is dynamically and transparently reassigned to one of the other physical links.
