IBM SC41-5420-04 manual Using X.25 PVC instead of SVC, Ibm

The network table contains the networks and the Internet address associated with the network. Socket applications use the getnetbyname() and getnetbyaddr() functions to access the information in the network table (Figure 61).

The protocols and services tables that are shipped contain standard information. The network tables do not contain any information. The network IBM information has been added in Figure 61, as an example.

For additional information about sockets, refer to Socket Programming (http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzab6/ rzab6soxoverview.htm) in the Information Center. If you are using the Supplemental Manuals CD, then switch to the iSeries Information Center CD to access this information.

Using X.25 PVC instead of SVC

In “Step 5—Configuring TCP/IP Remote System Information (X.25)” on page 16 you were shown how to define the X.25 network address of each system that uses a switched virtual circuit (SVC).

To replace the X.25 SVC with an X.25 permanent virtual circuit (PVC) connection, the example below is helpful. The following CL commands will look different: CRTLINX25, ADDTCPIFC, and ADDTCPRSI.

Use the same X.25 line description, but replace the first of the four SVCs with a PVC.

CRTLINX25 LIND(X25LINE) RSRCNAME(LIN051) LGLCHLE((001 *PVC) (002 *SVCBOTH)

(003 *SVCBOTH) (004 *SVCBOTH)) NETADR(40030003) CNNINIT(*LOCAL) TEXT('ITSO X.25 Network')
