Table 1-1. Example Alias LU Names
Configured
LU Name
Alias LU Name
Generated by SNAX/XF
#LU A $SNAP.#A100001
#LU B $SNAP.#A100002
#LU C $SNAP.#A100003
The next time a connection is made for that PU, the base alias LU name is different. To
continue with the example shown in Table 1-1, the three aliases for the next connection
might be $SNAP.#A100004, $SNAP.# A100005, and $SNAP.#A100006.
Alias LU names are an alternative to configured LU names; configured LU names still
exist in exactly the same form. Aliases relate to their configured LU names by the
order in which LUs are added to the PU. Users have the option of using either the
alias or the configured name. If the alias is not used, however, the user program must
determine the configured LU name.
SNAX/XF Service Manager The SNAX/XF service manager is the point through which SNAX/CM controls the
lines.
Communication Lines Underlying the connection management environment is a switched SNAX/XF
network configuration, along with either an X.25 or a Token-Ring network.
When specifying a line, SNAX/CM users can also identify a port. A port is a unique
name used by SNAX/CM to identify and access a particular TLAM I/O process for
Token-Ring networks or an X25AM line handler subdevice for X.25 networks. Up to
254 ports can be configured in a SYSGEN operation; SNAX/CM controls each port
independently and supports the connection of one switched PU for each port.
After the networks are configured and started, users can use SNAX/CM and its
associated processes to connect and disconnect different lines and PUs. Refer to
Section 2 in this manual for examples of how to configure lines to use with
SNAX/CM, and to the SNAX/XF Configuration and Control Manual for basic
information about configuring switched lines, X.25 lines, and Token-Ring networks.
Running SNAX/CM Users can start SNAX/CM either interactively using a TACL RUN command, or
programmatically by calling the NEWPROCESS procedure.
Using a RUN command, an operator can access SNAX/CM and issue commands to it
using the SNAX/CM command interpreter. Users can either use the command
interpreter interactively or specify a command file as the IN file in the RUN command.
The results of the commands contained in a RUN command list are included in the
OUT file.
