Saving Driver Parameters Beyond Reboot

Any parameter changes made using ndd will be lost the next time your system is rebooted. To keep changes through reboot, parameter settings must be placed in a start-up file with the following filename:

/etc/rc2.d/S99itialt

Example: If you need to adjust adapter 2 to turn Link Negotiation off and increase the TCP/IP values, you could place the following lines in the /etc/rc2.d/S99itialt start-up file:

#!/sbin/sh

#local kernel modification

case "$1" in 'start')

echo "Setting local kernel parameters...\c" ndd -set /dev/alt instance 2

ndd -set /dev/alt link_negotiation 0 ndd -set /dev/tcp tcp_recv_hiwat 65535 ndd -set /dev/tcp tcp_xmit_hiwat 65535 ndd -set /dev/udp udp_xmit_hiwat 65535 ndd -set /dev/udp udp_recv_hiwat 65535

echo " "

;;

'stop')

echo "$0: No parameters changed."

;;

*)

echo "Usage: $0 {startstop}"
