∙Use the ndd (1M) utility to temporarily change a parameter. This change is lost when you reboot the system.

Refer to the Platform Notes: The qfe Fast Ethernet Device Driver document for more information on configuring driver parameters. This document is also available on the Solaris™ AnswerBook.

Increasing TCP/IP performance

You can increase the TCP/IP performance of the ITI-8241C-S qfe adapter by changing the TCP highwater mark to 64K. This can be done with the ndd (1M) utility as follows.

As superuser, type:

#ndd –set /dev/tcp tcp_xmit_hiwat 65535

#ndd –set /dev/tcp tcp_recv_hiwat 65535

#ndd –set /dev/tcp tcp_cwnd_max 65534

The changes will take effect immediately and affect all system networking interfaces.

Manually Specifying 10Mbps or 100Mbps Connection

If you need to manually specify the speed of the network your ITI-8241C-S adapter is on, use the following process at the ok prompt:

Find the hme device from the ok prompt:

ok show-devs

Find the full name of the hme you want to boot, for example:

/pci@1f,0/pci@1/pci@2/IntraServer,qfe@0,1

Type:

ok nvedit

Type the following, press the return key at the end of line 0:

0:probe-all install-console banner

1:apply transfer-speed=10 /pci@1f,0/pci@1/pci@2/IntraServer,qfe@0,1

Note: To specify 100Mbit/sec operation, apply transfer-

speed=100

Press the Control-C keys after typing
