Which two statements about EtherChannel configuration and verification are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
On IOS-XE, the 'channel-group 1 mode active' command creates the port-channel interface automatically if it does not exist.
EtherChannel interfaces can be configured as Layer 2 (switchport) or Layer 3 (no switchport). The 'channel-group' command assigns a physical port to a port-channel. The 'show etherchannel summary' command displays the state and bundle information. On NX-OS, the 'channel-group' command uses the 'force' option to override mismatched parameters.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
On IOS-XE, the 'channel-group 1 mode active' command creates the port-channel interface automatically if it does not exist.
Why this is correct
Correct because when the first physical port is added with a mode that enables LACP, the port-channel interface is dynamically created.
- ✓
The 'show etherchannel load-balance' command displays the current load-balancing method and the hash algorithm used.
Why this is correct
Correct because this command shows the configured load-balancing method and, on some platforms, the hash algorithm details.
- ✗
In a Layer 3 EtherChannel, you must assign an IP address to the port-channel interface and also to each member interface.
Why it's wrong here
Incorrect because in a Layer 3 EtherChannel, the IP address is assigned only to the port-channel interface, not to the member interfaces.
- ✗
The 'channel-group 1 mode desirable' command is valid on both IOS-XE and NX-OS platforms.
Why it's wrong here
Incorrect because 'desirable' is a PAgP mode, which is not supported on NX-OS; NX-OS only supports LACP (active/passive) and 'on' mode.
- ✗
If physical ports in an EtherChannel have different speed or duplex settings, the EtherChannel will still form but with reduced bandwidth.
Why it's wrong here
Incorrect because all physical ports in an EtherChannel must have identical speed and duplex settings; otherwise, the EtherChannel will not form.
