The default values for network options on the AIX® operating system can be used for most IBM Spectrum Protect™ configurations.
Review the preferred network-related settings.
Procedure
- If you use 10 Gbit Ethernet adapters, enable flow control
on the switch or router port that the AIX system
is connected to. See your network administrator, or see the manuals
for your router or switch to determine how to enable flow control.
- If you set the TCPWINDOWSIZE option
to greater than 63, set the rfc1323 network option
to 1. To ensure that the new setting is used whenever the system is
restarted, use the -p option on the command. For example, issue the following command:
no -o rfc1323=1 -p
- If you see nonzero values for the no mbuf
errors field in the output from the entstat, fddistat,
or atmstat commands, increase the value for the thewall option.
Set the thewall option to at least 131072 and the sb_max option
to at least 1310720. Newer versions of the AIX operating system have larger defaults for
these options, and modifying them might not be necessary.
