3. LAGs 3 Link Aggregation Groups This chapter provides the following examples: • Create Two LAGs on page 35 • Add Ports to LAGs on page 36 • Enable Both LAGs on page 38 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. Port 1/0/3 LAG_10 Subnet 3 Port 1/0/2 Server LAG_10 Layer 3 Switch Port 1/0/8 LAG 20 Port 1/0/9 LAG_20 Layer 2 Switch Subnet 2 Subnet 3 Figure 4. Example network with two LAGs 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. Chapter 3. LAG s | 34
