Both ends of a link are set to PAgP auto. What should you expect?

  1. A

    No channel forms because neither side initiates negotiation.

  2. B

    A channel forms because both sides initiate negotiation.

  3. C

    A channel forms only if LACP is also enabled.

  4. D

    The ports form a channel without negotiation.
