Network Management Interface

Several TCP/IP callable NMI (EZBNMIFR) requests include information about SMC-R in general and specifics about IBM® 10GbE RoCE Express® interfaces:

• The GetConnectionDetail request provides information about active TCP connections, including SMC-R information for TCP connections that traverse SMC-R links.
• The GetGlobalStats request provides TCP/IP stack global statistics for IP, ICMP, TCP, UDP, and SMC-R processing.
• The GetIfs request provides TCP/IP stack interface attributes and IP addresses, including information about 10GbE RoCE Express interfaces.
• The GetProfile request provides profile information, including GLOBALCONFIG information for SMC-R.

In addition, two NMI requests that are specific to SMC-R information are available:

• The GetRnics request provides interface statistics and VTAM® tuning statistics that are related to 10GbE RoCE Express interfaces. This request provides similar information to what is returned on the GetIfStats and GetIfExtendedStats requests for traditional interfaces.
• The GetSmcLinks request provides statistics about active SMC-R link groups and the SMC-R links within the link groups.

For specifics about these TCP/IP callable NMI requests, see z/OS Communications Server: IP Programmer's Guide and Reference.
