SMC-R link state end record (subtype 43)
The SMC-R link state end record is collected whenever a Shared Memory Communications over Remote Direct Memory Access (SMC-R) link is ended. This record contains all pertinent information about the SMC-R link, such as the time the link started and ended, bytes transferred, and so on.
See Table 1 for the contents of the TCP/IP stack identification section. For the SMC-R link state end record, the TCP/IP stack identification section indicates SMCR as the subcomponent and X'08' (event record) as the record reason.
Table 1 shows the link
