Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)
Do this in CIP:If you use this MON/SUBNET attribute in TCP/IPv6:
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.ipv4.tcp_wmem 'value
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.
“TCPSENDSPACE” (page 197)
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.ipv4.tcp_tw_recycle
value
NOTE: Changes to this sysctl parameter must be made
on all CLIMs that share the same Provider.
This change in sysctl parameter requires a CLIM restart.
Connections that go through TCP state aware nodes, such
as firewalls, NAT devices or load balancers may see
dropped frames. The more connections there are, the more
likely you will see this issue.
“TCPTIMEWAIT” (page 198)
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.core.rmem_max value and
“UDPRECVSPACE” (page 198)
CLIMCMD clim-name climconfig sysctl -update
net.core.rmem_default 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.
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.core.wmem_max value and
“UDPSENDSPACE” (page 199)
CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.core.wmem_default 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.
Controlled by climconfig sysctl, with the default as ON.
CLIMCMD {clim–name | ip–address} climconfig
“IPV6RAENABLE” (page 199)
sysctl -update net.ipv6.conf.all.autoconf
0 CLIMCMD{clim–name | ip–address}
climconfig sysctl -update net.ipv6.conf.<
intf-name>.autoconf 0
NOTE: The above commands are for disabling IPv6
auto-configuration.
INITIAL-TTL
This NonStop TCP/IPv6 Monitor attribute, which specifies the initial value for UDP and
TCPtime-to-live, can be set by using the CLIMCMD {clim–name | ip–address} climconfig
sysctl -update net.ipv4.ip_default_ttl command.
HOSTID
This NonStop TCP/IPv6 Monitor attribute, which specifies the identification number (usually the
host number part of the Internet address that is assigned to this host) is set by using the NonStop
host system SCF commands ADD PROVIDER or ALTER PROVIDER. (See Section Chapter 10 (page 216)
for more information about the HOSTID attribute.)
