SNA Node and Link Configuration
NMMGR Configuration Overview
For dependent LUs and independent LUs, you must provide
information for the LU-LU sessions. For each LU defined in SNA
Transport, an LU must be defined in the host’s NCP/VTAM
configuration. You must configure each LU and establish a
correspondence with an LU in the NCP/VTAM configuration.
You configure these items for an SNA node:
• Node identification. This information identifies the node to the host
and specifies the type of node (T2.0 or T2.1) being used.
• Link type. This information specifies whether you are configuring an
SDLC link, an X.25 link, or a token ring link.
• PU data. This information identifies the PU to the host.
• LUs. A list of up to 256 LUs can be configured for an SNA node.
Link Information
After you specify configuration information for the SNA node, you
specify information for the link.
For an SNA/SDLC link, you provide this information:
• Link data. This information includes the PSI physical path, timeout
values, transmission speed, and link station ID.
• Phone data. This information includes the phone number and
associated data for switched lines.
For an SNA/X.25 link, you provide this information:
• Link data. This information is about the Network Services (NS)
network interface and the type of virtual circuit to be used.
• Virtual circuit data. This information is specifically about the
permanent virtual circuit (PVC) or switched virtual circuit (SVC) to
be used.
For an SNA/Token Ring link, you provide this information:
• Link data. This information is about the name and location of the
token ring card, the MAC address of the remote system, the local
and remote service access points (SAPs), and MAC layer timeout and
retry values.
NOTE If you change the configuration for an SNA node or link while it is
running, the changes will not take effect until the node or link is
restarted.
