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

NonStop TCP/IPv6 Attributes and Their CIP Equivalents
Many of the TCP/IP stack environment variables that you set by using attributes in the NonStop
TCP/IPv6 ALTER MON/SUBNET command are now set in the CLIM environment. This subsection
lists the attributes that you can configure on the NonStop TCP/IPv6 TCP6MON/SUBNET process
and an equivalent way of configuring that attribute in CIP. The following table shows NonStop
TCP/IPv6 attributes and the equivalent CIP action required to achieve the same result. For NonStop
TCP/IP attributes and their CIP equivalents, including default, minimum, and maximum values, see
Table 19: TCP/IP Attribute Default Values and Ranges (page 199).
Do this in CIP:If you use this MON/SUBNET attribute in TCP/IPv6:
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.ipv4.ip_default_ttl
value
“INITIAL-TTL” (page 195)
ADD PROVIDER“HOSTID” (page 195)
ADD PROVIDER“HOSTNAME” (page 196)
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.ipv4.ip_local_port_range
'value value'
NOTE: Changes to this sysctl parameter must be made
on all CLIMs that share the same Provider. Also, all
providers sharing a CLIM must similarly share that sysctl
value.
