Smcd Parameter In Globalconfig; D.3.10 Enabling Smc-D Support In Z/Os Communications Server - IBM z13s Technical Manual

Table D-2 shows a list of required APARs per z/OS subsystem.

Restrictions: SMC (existing architecture) cannot be used in these circumstances:
Peer hosts are not within the same IP subnet and VLAN
TCP traffic requires IPSec or the server exploits FRCA.

D.3.10 Enabling SMC-D support in z/OS Communications Server

The new parameter SMCD (see Figure D-19) will be available on the GLOBALCONFIG
statement in the TCP/IP profile of the z/OS Communications Server (similar to the SMCR
parameter). The SMCD parameter is the only parameter that is required to enable SMC-D.
The key difference from the SMCR parameter is that ISM PFIDs are not defined in TCP/IP.
Rather, ISM FIDs are discovered automatically based on matching PNETID associated with
the OSD or HiperSockets. Figure D-19 shows an extract from z/OS Communications Server:
