Which statements regarding LACP are true?

LACP, or Link Aggregation Control Protocol, is a protocol defined by IEEE 802.3ad (now part of IEEE 802.1AX), which enables the aggregation of multiple physical links into a single logical link. This is beneficial for increasing bandwidth and providing redundancy.

The first statement highlights that LACP is indeed derived from IEEE 802.3 standards, specifically relating to Ethernet. This standardization allows for consistent implementation across various network devices, facilitating compatibility and interoperability.

The second statement is accurate as well; local devices actively communicate with their remote counterparts through the use of LACPDUs (Link Aggregation Control Protocol Data Units). This communication is crucial for the negotiation of the aggregated link parameters and ensuring that both ends of the connection are synchronized and aware of the link aggregation status.

The third statement pertains to how LACP determines which side is active in the negotiation process. LACP uses the system priority value assigned to each device to establish which one will assume the active role in the aggregation. This system priority can help manage which device to prefer for the active configuration, allowing for a more controlled and efficient link aggregation setup.

Given that all three statements accurately describe aspects of LACP, the answer encompasses the correct understanding of this networking protocol
