What command displays general information about an EtherChannel?

1. show channel detail

2. show etherchannel ETHERCHANNEL NUMBER

3. show etherchannel ETHERCHANNEL NUMBER detail

4. show interfaces etherchannel

The correct answer is: show etherchannel ETHERCHANNEL NUMBER detail

The command that displays general information about an EtherChannel is indeed one that provides detailed insight into the configuration and operational status of a specific EtherChannel. The right command, which includes "detail," gives a comprehensive overview by not only confirming the EtherChannel's operational state but also revealing additional details about each port assigned to that EtherChannel, such as its status, protocol, and any potential misconfigurations. Using just the EtherChannel number without "detail" may limit the amount of information you receive, as it typically delivers a summary rather than an in-depth view. The first command would yield some basic channel information, but it would not provide the extensive details necessary for troubleshooting or configuration verification. The last option focuses on the interfaces instead of the EtherChannel itself, leading to less relevant information for the current context. Thus, the chosen command is favorable for gaining a thorough understanding of how the EtherChannel is set up and functioning.
