This sets the time interval, in seconds, over which CEF traffic statistics are collected and averaged. This interval determines the time resolution of derived load metrics; a short interval reacts quickly to bursty traffic changes but can look noisy, while a longer interval smooths out reported load figures at the cost of hiding short spikes, so the choice affects how responsive an admin's traffic-based decisions, like triggering load-balancing changes, actually are. An admin monitoring for brief traffic bursts on a critical link might shorten this interval from a 5-minute default to 30 seconds to get load statistics fine-grained enough to catch those bursts rather than having them averaged away.
