BIND Parameters
SSNDPAC ssndpac-value
specifies the secondary receive pacing count (byte 8 of the BIND image). Any
hexadecimal number in the range of %H00 to %H3F can be specified for
ssndpac-value.
The default value is %H00.
SRCVPAC srcvpac-value
specifies the secondary send pacing count (byte 9 of the BIND image). Any
hexadecimal number in the range of %H00 to %H3F can be specified for
srcvpac-value.
The default value is %H00.
RUSIZES rusizes-value
specifies the maximum length of data (in bytes) that can be sent by secondary LU
and primary LU (bytes 10 and 11 of the BIND image). The rusizes-value takes the
form %Habcd, where the maximum RU length sent by the SLU is (ax2
b
) and the
maximum RU length sent by the PLU is (cx2
d
). For example, %H8989 means both
maximum RU lengths are 8 x 2
9
or 4096. a and c must be in the range %H8
through %HF while b and d must be in the range %H0 through %HF. If ab or cd is
zero, there is no maximum RU length for that LU.
The defaults depend on the remote LU protocol, as shown here:
PSNDPAC psndpac-value
specifies the secondary send pacing count (byte 12 of the BIND image). Any
hexadecimal number in the range of %H00 to %H3F can be specified for
psndpac-value. Primary receive pacing count (byte 13 of the BIND image) is
also set to the value set for PSNDPAC.
The default value is %H00.
Protocol SLU default PLU default
CRT/ITI/PRT Remote LU RECSIZE or 256
(whichever is larger)
Remote LU RECSIZE or 8
(whichever is larger)
NAM 4096 4096
Notes.
1. SNAX/XF and SNAX/APN always use these default values as the maximum send and
receive RU lengths whatever the BIND parameters are, so custom BINDs should use
values greater or equal to the defaults to avoid unpredictable results.
2. When a SNAX/APN LU sends a BIND through SNAX/APN to an SNA subarea
network, VTAM checks that the RUSIZES values are less than or equal to the
RUSIZES values in the default logon mode entry for the remote LU. (The default logon
mode entry is specified in the DLOGMOD parameter of the LU entry in the VTAM list.)
