This counter reports the total number of frames of ingress traffic on this element that matched the configured access/classification rule being measured here. Read alongside the matching AllTime-bin AccessHitBytes counter, it lets you track whether the average frame size hitting this rule has changed over its entire tracked lifetime, which a single recent 15-minute bin can't show you since that only reflects one narrow window. For instance, an average frame size that has quietly drifted from around 1500 bytes to under 200 bytes since this counter was first created suggests the customer's traffic profile on this classified service has shifted away from bulk transfers, worth revisiting the rule's intent.
