LAGs
Link Aggregation Groups
This chapter provides the following examples:
Link aggregation allows the switch to treat multiple physical links between two end-points 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 offers 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.
