14-35
MAXPUS
The valid range of values is 0 through the value specified for the MAXLUS attribute for
this PU.
When you add the PU, you need not specify a value for MAXPTS. In such a case,
MAXPTS is set equal to the value specified for the MAXLUS attribute. Note, however,
that any subsequent altering of the MAXLUS attribute does not change the value of
MAXPTS.
MAXPUS
MAXPUS specifies the maximum number of PUs and ports that can be associated with
a given line. For SNAX/APN, MAXPUS specifies the maximum number of SNAX/APN
remote PUs that can be subordinate to the given line, along with the number of
SNAX/XF PUs that might share that line.
For nonswitched lines, the value of MAXPUS can range from 1 through 254.
For switched X.25 and Token-Ring lines, the value of MAXPUS can also range from 1
through 254. Specifying more than one PU per switched X.25 line supports larger
switched networks. In this case, the ADD or ALTER command must specify that the
CONNECTAPPL attribute equals ANY or cmapplname, and the SNAX/CM process is
required to control activation of the network.
For switched line type 58,5 (SDLC), which are not supported by SNAX/CM, the only
value allowed is 1. When you specify MAXPUS in an ADD or ALTER command, you
should specify IOPAGES as 0 in the same command; an appropriate value for
IOPAGES is then automatically calculated. If you do not specify IOPAGES, the line
handler retains the value established for IOPAGES in previous ADD or ALTER
commands. If you specify IOPAGES with a value other than 0, the line handler sets
IOPAGES to the specified value. In either case, the value might not provide enough
memory to accommodate the new MAXPUS specification, causing the SCF command
to be rejected.
MAXRCVSIZE - for SNAX/APN Only
MAXRCVSIZE specifies the maximum number of bytes contained in a SNAX/APN
basic transmission unit (BTU). It has no meaning for type 2.0 PUs that might share the
