What are the four supported modes of LACP?

Link Aggregation Control Protocol (LACP) is a standard used to combine multiple physical links into a single logical link to enhance bandwidth and provide redundancy. The correct answer outlines the four operational modes of LACP, which specifically are "Active" and "Passive."

In the context of LACP:

• The "Active" mode allows a device to initiate LACP negotiations with other devices to form the link aggregation group (LAG). When a port is in active mode, it is actively sending LACP packets.

• The "Passive" mode means that the device will respond to LACP packets but will not initiate the negotiations.

The "On" state indicates that the link aggregation is enabled but does not use LACP for negotiation. The "off" state suggests that the port is not participating in any link aggregation.

The other choices include terms or states that do not accurately reflect LACP's supported modes. Terms like "Standby," "Backup," "Enabled," and "Disabled" may relate to different contexts or protocols but are not valid modes for LACP operation. Knowing these distinctions is crucial for accurately configuring and troubleshooting network link aggregation.
