The high-word of the counter of packets permitted
by this rate limit.
NOTE: The object ccarStatSwitchedPkts contains the
lower 32 bits of the switched packet counts.
If the number of switched 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
ccarStatSwitchedPkts object to come up with the
64-bit value.
SNMP v2c or v3 Manager can use the
ccarStatHCSwitchedPkts object directly
(which is a 64-bit object).
