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 or ACC physical path,

timeout values, transmission speed, and link station ID.

• Phone data. This information includes the phone number and

associated data for switched lines. At present, ACC does not support

dialing facility.

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.
