Question and answers are wiered: -according to config snippet SW2 G0/0 is not configured to participate in the channel -according to show command none of the Interfaces is participating in the Channel But i can't find a mistake why G0/1 is not working. The given answer is the best i can find, but it will not fix that all interfaces participate in teh channel afterwards

this exhibit makes few sense anyway as LACP on the gi0/1 should converge

No correct answer, just tested all of the answers and nothing works. it should be choose two then set the port to trunk and enable LACP.

Can someone explain why Gi0/1 is down if everything is matching correctly?

Clearly the G0/0 link is the problem, but wondered why G0/1 would not come up. Then realized not only is there a link state mismatch, but the Ethernet pair on the same switch is a mismatch so LACP throws the whole thing out, even though G0/1 between switches is a match

2 configurations need to be done #1 on SW2 need to set G0/0 to Trunk #2 on SW2 need to set G0/0 to LACP Mode Active < If you don't set this up it will not bundle and it will be missing the config.

Apparently the exhibit given here has that cut off. But it has to be implied it is there, since show eth summ shows that G0/0 is a candidate.

Answer B is correct. Just the typo in SW2 Gi0/0 config snippet. Where ther is missing " channel-group 1 mode active". SW2 Gi0/0 , switchport mode access need to chagne to trunk.

The answer B would not bring the etherchannel up. For the etherchannel to be up, we need 'channel-group 1 mode active on SW2 go0/0.' There are two issues in the config of Gi0/0 of SW2.

wasn't trunk mode known to be sending out DTP packets, despite being a static configuration? when we use 'swi mode trunk' by default dtp packets will be sent unless we issue 'switchport nonegotiate'

But switchport nonegotiate IS configured.

All the physical interfaces in the ether-channel must have the same config (access/trunk, allowed VLANs, duplex, speed) to form logical channel. Correct answer is B
