Which command would be used to display the status of the EtherChannel interface?

1. #show etherchannel interfaces

2. #show interfaces summary

3. #show etherchannel summary

4. #show port status

The correct answer is: #show etherchannel summary

The command that is used to display the status of the EtherChannel interface is "show etherchannel summary." This command provides a comprehensive summary of the EtherChannel interfaces, including their operational status, the ports included in the EtherChannel, and whether they are up or down. It facilitates troubleshooting by allowing network administrators to quickly ascertain the health and configuration of the EtherChannel configuration on the switch. Additionally, this command presents specific information such as the protocol being used for the EtherChannel, the number of active and inactive ports, and other vital metrics that aid in assessing the effectiveness and reliability of the EtherChannel. This level of detail is crucial for identifying any issues with link aggregation and ensuring that bandwidth requirements are met effectively. While the other options may provide useful information, they do not target the specific details and summary of the EtherChannel configuration as accurately and comprehensively as "show etherchannel summary" does. This makes it the most effective choice for monitoring EtherChannel interfaces.
