1. Create a file /etc/rc2.d/S99tunehme.sh:\r\n\r\n#!/sbin/sh\r\nndd -set /dev/hme instance 0\r\nndd -set /dev/hme adv_100fdx_cap 1\r\nndd -set /dev/hme adv_100hdx_cap 0\r\nndd -set /dev/hme adv_10fdx_cap 0\r\nndd -set /dev/hme adv_10hdx_cap 0\r\nndd -set /dev/hme adv_autoneg_cap 0\r\n\r\n2. Set permissions:\r\n\r\nchmod 755 /etc/rc2.d/S99tunehme.sh\r\nchgrp sys /etc/rc2.d/S99tunehme.sh\r\n\r\n3. Reboot or bring down/up the interface:\r\n\r\nifconfig hme0 down\r\n/etc/rc2.d/S99tunehme.sh\r\nifconfig hme0 up\r\n\r\n4. Check log to see if all is well:\r\n\r\ntail /var/adm/messages\r\n\r\nhme: [ID 517527 kern.info] SUNW,hme0 : Internal\r\nTransceiver Selected.\r\n hme: [ID 517527 kern.info] SUNW,hme0 :   100 Mbps\r\nFull-Duplex Link Up

ndd -set /dev/hme instance 0 \r\nndd -set /dev/hme adv_100fdx_cap 1 \r\nndd -set /dev/hme adv_100hdx_cap 0 \r\nndd -set /dev/hme adv_10fdx_cap 0 \r\nndd -set /dev/hme adv_10hdx_cap 0 \r\nndd -set /dev/hme adv_autoneg_cap 0 \r\n这些都是做什么的参数？？\r\n期待中，学习

說實話我也不是很明白。是上一次SUN給的。我就照著做了，沒有去細想，沒有問題。
