What command will show information about all switchport interfaces configured on a EtherChannel port channel?

show interfaces port-channel
show port-channel interfaces
show interfaces port-channel PORT CHANNEL NUMBER
show etherchannel interfaces

The correct answer is: show interfaces port-channel PORT CHANNEL NUMBER

The command that provides information about all switchport interfaces configured on an EtherChannel port channel is indeed the one that specifies the port channel number. Using this command allows the network administrator to focus on a specific port channel and view detailed information regarding its configuration and status, including the individual member interfaces and their operational states. When you specify the port channel number, it helps narrow down the output to only relevant details about that particular EtherChannel, making it more efficient for troubleshooting or verifying configurations. This command can reveal important attributes such as the protocol being used, the member interfaces, and their modes (like access or trunk). While other commands might provide some useful information, they may not focus specifically on the configuration of all switchport interfaces within the context of the specific port channel, which this command does effectively.
