Which mode in LACP allows both ends to be active in negotiation?

• A. Passive Mode
• B. Active Mode
• C. On Mode
• D. Auto Mode

Answer: (B)

Active Mode in Link Aggregation Control Protocol (LACP) is designed to allow both ends of a connection to participate in the negotiation of a link aggregation group. When a port on a switch is set to Active Mode, it actively initiates the negotiation process by sending LACP packets. This allows the switch to form a logical link aggregation with another switch that is also configured to use LACP. In Active Mode, both switches can potentially be configured in the same way, which defines a full negotiation capability for creating EtherChannel links. This means that if both ends are in Active Mode, the LACP process will work effectively to bundle multiple physical links into a single logical link, improving redundancy and throughput. The other modes, such as Passive Mode, do not initiate negotiations themselves. A switch in Passive Mode will only respond to LACP packets received from a neighboring switch that is in Active Mode. Therefore, it does not have the same dynamic negotiation capability as Active Mode. Overall, Active Mode's ability to actively negotiate makes it critical for establishing and maintaining efficient link aggregation in network environments.
