The high-word of the counter of packets which exceeded
this rate limit.
NOTE: The object ccarStatFilteredPkts contains the
lower 32 bits of the filtered packet counts.
If the number of filtered packets is larger
than what can be stored in a 32 bit value, then
the high word value is stored in this object.
As such SNMP Manager applications should combine
this object along with the ccarStatFilteredPkts
object to come up with the 64-bit value.
SNMP v2c or v3 Manager can use the
ccarStatHCFilteredPkts object directly
(which is a 64-bit object).
