Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

Host Id
scf> INFO Provider $ZZCIP.provider-name, DETAIL. Is the ID (usually the host
number part of the Internet address that is assigned to this host). It is a 32-bit number.
Host Name
scf> INFO Provider $ZZCIP.provider-name , DETAIL. Is the official name by
which the host upon which the TCP/IP process is running is known in the Internet. This is a
character string no longer than 50 characters.
Debug
No longer applies in the CIP environment.
Full Dump
No longer required for the CIPSAM process as there is a dump function on the CLIM.
ALLNETSARELOCAL
No longer applies in the CIP environment. ALLNETSARELOCAL set to ON causes TCP to use
the interface MTU as a base for the determination of the TCP Maximum Segment Size (MSS)
for each non-local TCP connection. A non-local TCP connection is one that goes to another
network (not just another subnetwork). The default is ON. If this switch is OFF, TCP conforms
to RFC-specified behavior and uses 512 bytes as the default MSS for non-local segments. When
ON, for example for Ethernet, the non-local MSS is 1460. This can be a large benefit to
performance.
TCPCOMPAT42
No longer applies in the CIP environment. TCPCOMPAT42 was the flag used to set the TCP/IP
process compatible with BSD4.2 versions. See “TCPCOMPAT42” (page 202) for more information
about this feature.
EXPANDSECURITY
No longer applies in the CIP environment. EXPANDSECURITY set to ON caused TCP to check
if a SOCKET request from another NonStop Expand node has passed the Expand security
check.
TCPPATHMTU
tacl> CLIMCMD clim-name sysctl net.ipv4.ip_no_pmtu_disc . If set to ON,
causes TCP to use PATH MTU discovery on all TCP type sockets (SOCK_STREAM), unless
disabled by the SETSOCKOPT for SO_PMTU. The default for this option is OFF. See also
“TCP/IP Attributes in CIP” (page 193).
RFC1323-ENABLE
tacl> CLIMCMD clim-name sysctl net.ipv4.tcp_window_scaling . If set to ON,
causes TCP to support TCP Large Windows as documented in RFC 1323. When this option is
enabled, the TCP/IP process uses the TCP Window Scale and Timestamp options as described
in RFC 1323. The largest TCP window supported is 262144 bytes when this option is enabled,
and 65535 when the option is disabled. The default for this option is ON.
TCP-INIT-REXMIT-TIMEOUT
Not supported in the CIP environment. TCP-INIT-REXMIT-TIMEOUT was the initial retransmit
timer value in milliseconds to use on a TCP connection.
TCP-MIN-REXMIT-TIMEOUT
Not supported in the CIP environment. TCP-MIN-REXMIT-TIMEOUT was the minimum value
allowed for the TCP retransmission timeout.
TCP-LISTEN-QUE-MIN
scf> INFO Provider $ZZCIP.provider-name, DETAIL. Is the minimum queue length
that is set on a TCP socket when the TCP/IP process handles a socket LISTEN or ACCEPT_NW1
function call. This value is used if the queue length specified in the socket request is lower,
