The command used to identify the EtherChannel’s operational status is "show etherchannel summary." This command provides a concise overview of all EtherChannels configured on a device, displaying important information such as the number of interfaces bundled in the EtherChannel, their operational state (up or down), protocol information (if any), and additional details regarding the load balancing method being utilized.

Utilizing this command allows network administrators to quickly assess the health of the EtherChannels on the switch or router, making it easier to troubleshoot connectivity issues or verify that the EtherChannel is functioning as expected. It combines information from multiple interfaces into a single view, which is particularly helpful when managing complex network configurations.

The other commands listed do not conform to standard Cisco IOS command syntax and would not yield valid results. Therefore, the "show etherchannel summary" command stands out as the correct choice for identifying the operational status of an EtherChannel.
