Several SMF 119 records include information about SMC-R in general
and specifics about IBM® 10GbE
RoCE Express® interfaces.
In addition, SMF TYPE 119 records that are specific to SMC-R processing
are available:
- The SMC-R Link State Start (subtype 42) and SMC-R Link State End
(subtype 43) SMF records notify the user when an SMC-R link is activated
or deactivated. These SMF records serve a similar purpose for SMC-R
links as the TCP Connection Start and TCP Connection End records serve
for TCP connections.
- The SMC-R Link Group Statistics SMF record (subtype 41) provides
statistics for all active SMC-R link groups on an interval basis.
This SMF record includes information pertinent to both SMC-R link
groups and the individual SMC-R links that comprise the link group.
- The RNIC Interface Statistics SMF record (subtype 44) provides
interface statistics for 10GbE RoCE Express interfaces.
This SMF record serves the same purpose for 10GbE RoCE Express interfaces that the Interface Statistics
SMF record (subtype 6) serves for other interfaces.
