Section5.10
Managing Link Aggregation
Link aggregation, also referred to as port trunking or port bundling, provides the ability to aggregate or gather
several Ethernet ports into one logical link (port trunk) with higher bandwidth. This allows for highly randomized
load balancing between the aggregated links based on both the source and destination MAC addresses of the
forwarded frames.
Link Aggregation can be used for two purposes:
• To obtain increased, linearly incremental link bandwidth.
• To improve network reliability by creating link redundancy. If one of the aggregated links fails, the switch will
balance the traffic between the remaining links.
