Kim, a network administrator, is configuring a switch with an LACP port group for uplink. She plugs in the secondary uplink of the group, and shortly thereafter receives widespread reports that the network is malfunctioning. Which of the following is MOST likely the cause?
A.
A network loop was created due to a misconfiguration of the port group.
B.
The port on the switch for the new secondary link was never enabled.
C.
The LACP group was mistakenly configured to do layer 2 + 3 + 4 hashing for its link balancing.
D.
The LACP group was only configured to do layer 2 hashing for its link balancing.
Within the IEEE specification the Link Aggregation Control Protocol (LACP) provides a method to control the bundling of several physical ports together to form a single logical channel. LACP allows a network device to negotiate an automatic bundling of links by sending LACP packets to the peer (directly connected device that also implements LACP).
