Question:
A network administrator has configured an EtherChannel between two switches that are connected via four trunk links. If the physical interface for one of the trunk links changes to a down state, what happens to the EtherChannel?

  • Spanning Tree Protocol will transition the failed physical interface into forwarding mode.
  • Spanning Tree Protocol will recalculate the remaining trunk links.
  • The EtherChannel will transition to a down state.
  • The EtherChannel will remain functional.

Explanation: EtherChannel offers redundancy by bundling multiple trunk links into one logical connection. Failure of one physical link within the EtherChannel will not create a change in the topology and therefore a recalculation by Spanning Tree is unnecessary. Just one physical link must remain operational for the EtherChannel to continue to function.
