Network connection with an unacceptable residual error rate.
ZCLASS
shows the preferred transport protocol class. The values for this field are:
ZOS4-VAL-CLASS-0
ZOS4-VAL-CLASS-1
ZOS4-VAL-CLASS-2
ZOS4-VAL-CLASS-3
ZOS4-VAL-CLASS-4
ZALT-CLASS
shows the alternative protocol class used if the class specified in ZCLASS is
not supported by the remote system. If ZCLASS has the value ZOS4-VAL-
CLASS-0, then ZALT-CLASS is not applicable. The values for this field are the
same as for ZCLASS:
ZOS4-VAL-CLASS-0
ZOS4-VAL-CLASS-1
ZOS4-VAL-CLASS-2
ZOS4-VAL-CLASS-3
ZOS4-VAL-CLASS-4
The valid combinations of preferred protocol class and alternative protocol
class are as follows:
Preferred Class Alternative Classes
0 not applicable
1 0 or 1
2 0 or 2
3 0 or 1 or 2 or 3
4 0 or 1 or 2 or 3 or 4
ZTPDU-SIZE
shows the maximum length of a transport protocol data unit (TPDU) in bytes.
Acceptable values for this field are 128, 256, 512, 1024, 2048, 4096, and 8192
bytes.
ZXSUM
shows whether the checksum field is added to each TPDU. This field is
applicable only for protocol class 4 communication. If set to ZSPI-VAL-TRUE,
the checksum field is added; if set to ZSPI-VAL-FALSE, the checksum is not
added.
