This read-only Counter32 (in 64KB-equivalent blocks per the MIB's own unit description) tracks the count of packets from a subscriber that conformed to their configured traffic profile. Admins use it alongside the byte counters to see whether a subscriber's in-profile traffic is made up of many small packets or fewer large ones, useful for capacity planning. For example, a high conforming-packet count with a comparatively low conforming-byte count would suggest the subscriber's compliant traffic is small-packet-heavy, such as VoIP.
