A building-permits desk depends on a port-channel between city halls and must keep the logical channel up if one member fiber fails. What behavior should operators expect from a correctly formed EtherChannel?
Select an answer to reveal the explanation.
Short Explanation
A healthy EtherChannel is a braided rope—cut one strand and the braid still holds. Remaining members keep the logical link up while hash moves flows onto survivors. That’s why the permits desk bundles fiber between halls instead of betting on one strand.
Full Explanation
A properly formed port-channel remains up when at least one member is operational, and traffic is redistributed across surviving links according to the load-balance algorithm. Loss of a single member should not require tearing down the logical interface. STP runs on the port-channel interface and is not a reason to disable loop prevention. Prefer LACP negotiation and member diversity so a single fiber cut leaves capacity online.
