Which command shows specific switchport EtherChannel information including trunking status?

1. show interfaces port-channel ETHERCHANNEL NUMBER

2. show port-channel switchport

3. show vlan port-channel

4. show switchport status

The correct answer is: show interfaces port-channel ETHERCHANNEL NUMBER

The command that provides specific switchport EtherChannel information, including trunking status, is indeed the command that displays the interface configuration for a specific Port Channel interface. This command shows detailed information such as whether the Port Channel is configured for trunking, and it provides insights about the allowed VLANs, native VLANs, and other switchport-related settings. When using this command, you can gain visibility into the operational parameters and statuses of the EtherChannel, which is crucial for troubleshooting connectivity issues and ensuring that the link aggregation is functioning as intended. This level of detail helps network administrators manage and optimize their configurations more effectively. Other commands listed might provide some relevant information but do not focus specifically on the switchport characteristics of EtherChannels. Understanding the unique capabilities of each command is key for effective network management and monitoring.
