This read-only counter tallies packets permitted by this rate limit as a 64-bit High Capacity version of ccarStatSwitchedPkts, intended for use with SNMPv2c or v3 managers. Unlike ccarStatSwitchedPkts and ccarStatSwitchedPktsOverflow, which require a manager to manually combine two separate 32-bit objects, this object is a native 64-bit counter reporting the same switched-packet total in one value, so on a manager that supports it, this single object replaces the manual high-word/low-word arithmetic needed for the older pair. An SNMPv3-capable monitoring tool would poll this single 64-bit object instead of separately fetching and combining ccarStatSwitchedPkts and ccarStatSwitchedPktsOverflow to get the same total.
