Which command is correct for configuring load balancing on an EtherChannel link?

The command for configuring load balancing on an EtherChannel link is correct when specified as "Switch(config)# port-channel load-balance method." This command allows the network administrator to define how traffic is distributed across the individual links within the EtherChannel.

Load balancing is crucial in EtherChannel configurations because it helps optimize bandwidth utilization and enhance performance by distributing traffic evenly across multiple physical links. By using the "port-channel" command followed by "load-balance method," the administrator specifies the algorithm that will determine how packets are distributed. This could be based on various parameters such as source and destination IP address, MAC address, or Layer 4 information, depending on the setup and the capabilities of the switches in use.

Each EtherChannel can use different load balancing methods based on the specific network needs and traffic patterns. Thus, understanding and properly configuring this command is essential for effective network management and performance optimization.
