In static LACP mode, which statement is false regarding the interface priority?

In static LACP (Link Aggregation Control Protocol) mode, it is important to understand how interface priority works in relation to link aggregation. The assertion that "a higher bandwidth link must always support LACP" is incorrect because the implementation of LACP is not mandated by link bandwidth. LACP can be used regardless of the specific bandwidth of a link, as long as it is configured and supported by the network equipment involved. Therefore, a higher bandwidth link does not inherently require or ensure that LACP is enabled or supported.

The other statements correctly describe aspects of LACP functionality.

The idea that a larger LACP priority leads to a higher probability of active interface status is pertinent because LACP uses priority values to determine which links should be active. Generally, a lower numerical value indicates a higher priority.

The functionality of active interfaces forwarding data while inactive ones do not is fundamental to how aggregation works, ensuring efficient utilization of available bandwidth.

Finally, the fact that a backup interface can transition to active when the current active interface fails highlights the redundancy feature built into link aggregation, allowing for seamless failover.

Thus, understanding how LACP operates with respect to interface priorities, link bandwidth, and redundancy allows for effective network management and optimization.
