never generated for this counter. The value initially set by the OSI manager is
0.
ZOUTBOUND-TPDU-PROTO-ERR-THLD
is the threshold value that the Transport Layer compares to the counter
ZOUTBOUND-TPDU-PROTO-ERR. This counter records the number of times
the Transport Layer receives a DR-TPDU or an error transport protocol data
unit (ER-TPDU) as the response to any TPDU it initiated (other than the CR-
TPDU). OSI/TS generates a ZOS4-EVT-L4-THLD event message whenever
the counter value is nonzero and dividing the counter value by the threshold
value leaves a remainder of zero. The values range from 0 through 65535. If
the threshold is set to 0, L4-THLD event messages are never generated for this
counter. The value initially set by the OSI manager is 0.
ZINBOUND-TPDU-XSUM-ERR-THLD
is the threshold value that the Transport Layer compares to the counter
ZINBOUND-TPDU-XSUM-ERR. This counter records the number of times
the Transport Layer discards a TPDU because of a checksum failure. OSI/TS
generates a ZOS4-EVT-L4-THLD event message whenever the counter value is
nonzero and dividing the counter value by the threshold value leaves a
remainder of zero. The values range from 0 through 65535. If the threshold is
set to 0, L4-THLD event messages are never generated for this counter. The
value initially set by the OSI manager is 0.
ZL4-TIMEOUT-THLD
is the threshold value that the Transport Layer compares to the counter ZL4-
TIMEOUT. This counter records the number of times the Transport Layer
exceeds its persistence time or maximum number of retransmissions in
attempting to send a TPDU. OSI/TS generates a ZOS4-EVT-L4-THLD event
message whenever the counter value is nonzero and dividing the counter
value by the threshold value leaves a remainder of zero. The values range
from 0 through 65535. If the threshold is set to 0, L4-THLD event messages are
never generated for this counter. The value initially set by the OSI manager is
0.
ZCHECK-TSEL
specifies whether checksum fields are added to CC-TPDUs.This attribute is
valid only when ZCLASS is 4. The possible values are:
ZSPI-VAL-TRUE
ZSPI-VAL-FALSE
ZSPI-VAL-TRUE specifies to add checksum fields. The default is ZSPI-VAL-
FALSE.
