As of J06.10 and later J-series RVUs and H06.21 and later H-series RVUs, this problem has been
fixed.
Error on Sockets When CIPSAM Process Aborts
In NonStop TCP/IPv6, when a SAM process is aborted, all existing sockets created using that SAM
return an error on the current or next operation. In CIP, when a SAM process is aborted, existing
sockets continue unaffected, but no new sockets can be created. To obtain behavior similar to
NonStop TCP/IPv6, abort the Provider object.
Connecting to Non-Loopback Address after Binding to Loopback
Conventional TCP/IP and NonStop TCP/IPv6 allow a socket bound to a loopback address to
connect to any local address, whether it is a loopback address or not. CIP allows such sockets
only to connect to a loopback address.
CIPSAM Commands
NonStop TCP/IPv6 provides a socket access method (SAM) SCF and SPI interface matching that
of conventional TCP/IP for applications using that interface to get information about the TCP/IP
subsystem. CIP also provides a SAM interface for the same reason, but supports fewer commands.
Data that does not exist on CIP is displayed as dummy data for compatibility reasons.
