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 AccessHitBytes counter for that completed day, it lets you compute the average size of the frames actually hitting this rule, which helps distinguish whether the matched traffic is mostly small control/signaling packets or full-size data frames. For instance, over that completed day an average of roughly 1500 bytes per matched frame points to bulk data traffic hitting the rule, while an average closer to 64 bytes would point to control or keepalive traffic instead.
