TCP/IP profile record interface section

This section provides network interface information from the DEVICE, LINK, HOME, BSDROUTINGPARMS, and INTERFACE profile statements. For IPv4 interfaces, the IP address is included in the interface information. Only the subnet mask value from the BSDROUTINGPARMS statement is included in the interface information. For IPv6 interfaces, the IP addresses are provided in the IPv6 address section.

There can be multiple sections in the record, one per interface. Information from DEVICE, LINK, HOME, and BSDROUTINGPARMS statements for an interface is combined into one section. If more than one additional IPv4 loopback IP address has been configured, there are multiple sections for the IPv4 loopback interface, one per additional IP address.

Information for only the following types of network interfaces is provided in this section:

Loopback: The loopback section is provided only if additional loopback IP addresses besides the default address, 127.0.0.1, have been configured.
OSA-Express QDIO Ethernet: MPCIPA/IPAQENET or IPAQENET6
HiperSockets™: MPCIPA/IPAQIDIO or IPAQIDIO6
Static MPC Point-to-point: MPCPTP or MPCPTP6
Static VIPA: VIRTUAL or VIRTUAL6

Information for dynamic XCF and dynamic VIPA interfaces is not supported in this section. Information for dynamic XCF interfaces can be found in the IPv4 and IPv6 configuration sections. Information for dynamic VIPA interfaces can be found in the dynamic VIPA address section.

If other types of network interfaces are defined to the TCP/IP stack, their presence is indicated by a flag bit in the NMTP_PICODepStmts and NMTP_PICODepChanged fields of the profile information common section.

Table 1 shows the TCP/IP profile record interface section.
