Which two of the following commands can be used to check the status of the member interfaces and the logical channel interface? (Choose two.)
- show etherchannel group-number detail
- show ip interface brief
- show etherchannel load-balance
- show etherchannel traffic
- show etherchannel summary
Explanation: To effectively monitor and troubleshoot an EtherChannel bundle, network administrators utilize specific diagnostic commands that reveal the health of both the logical port-channel and its underlying physical member interfaces. The show etherchannel summary command is the most common tool, providing a concise one-line status for each channel group that indicates whether the logical interface is functional and which specific ports are successfully bundled, suspended, or operating independently. For a more comprehensive analysis, the show etherchannel <group-number> detail command provides granular data regarding the port-channel's operational state and protocol-specific parameters, which is essential for identifying why a link might not be aggregating correctly. While other commands like show etherchannel load-balance and show etherchannel traffic are useful for analyzing the distribution of frames across links or viewing throughput statistics, they do not provide the primary status information required to verify if the interfaces are correctly bundled into the logical channel. Therefore, these two specific commands are the standard for verifying the basic operational integrity of a Layer 2 or Layer 3 EtherChannel.
