Setting the Network Interface speed under Solaris
ndd is used to change network interface card settings. e.g.
ndd -set /dev/hme instance 0 (choose hme0)
ndd -set /dev/hme adv_a00_fdx_cap 1 (set speed to 100 full duplex)
ndd -set /dev/hme adv_autoneg_cap 0 ( don’t auto negotiate)
Usually the settings are put into /etc/system as below (in the example below the settings would apply to all hme cards).
If you need to set individual cards, you will need to edit /kernel/drv/hme.conf. this will override what’s in /etc/system. You can get the card instance bu using prtconf -v
