hme Interface 100BaseT and Full Duplex Setup

Method A) Using ndd
Method B) Modifying /etc/system

1. Check with the following commmands:

       # ndd -get /dev/hme link_status 
       # ndd -get /dev/hme link_speed 
       # ndd -get /dev/hme link_mode
   
       link_status (read only)
            0 for Link Down
            1 for Link up
   
       link_speed (read only)
            0 for 10 Mbps
            1 for 100 Mbps
   
       link_mode (read only)
            0 for Half-Duplex mode
            1 for Full-Duplex mode 
   	

2. Using ndd

               1.1. hme interface = 10MB full duplex
   
                    # ndd -set /dev/hme adv_100T4_cap 0
                    # ndd -set /dev/hme adv_100fdx_cap 0
                    # ndd -set /dev/hme adv_100hdx_cap 0
                    # ndd -set /dev/hme adv_10fdx_cap 1
                    # ndd -set /dev/hme adv_10hdx_cap 0
                    # ndd -set /dev/hme adv_autoneg_cap 0
   
               1.2. hme interface = 10MB half duplex
   
                   # ndd -set /dev/hme adv_100T4_cap 0
                   # ndd -set /dev/hme adv_100fdx_cap 0
                   # ndd -set /dev/hme adv_100hdx_cap 0
                   # ndd -set /dev/hme adv_10fdx_cap 0
                   # ndd -set /dev/hme adv_10hdx_cap 1
                   # ndd -set /dev/hme adv_autoneg_cap 0
   
               1.3. hme interface = 100MB full duplex
   
                   # ndd -set /dev/hme adv_100T4_cap 0
                   # ndd -set /dev/hme adv_100fdx_cap 1
                   # ndd -set /dev/hme adv_100hdx_cap 0
                   # ndd -set /dev/hme adv_10fdx_cap 0
                   # ndd -set /dev/hme adv_10hdx_cap 0
                   # ndd -set /dev/hme adv_autoneg_cap 0
   
               1.4. hme interface = 100MB half duplex
   
                   # ndd -set /dev/hme adv_100T4_cap 0
                   # ndd -set /dev/hme adv_100fdx_cap 0
                   # ndd -set /dev/hme adv_100hdx_cap 1
                   # ndd -set /dev/hme adv_10fdx_cap 0
                   # ndd -set /dev/hme adv_10hdx_cap 0
                   # ndd -set /dev/hme adv_autoneg_cap 0
   	

3. Modifying /etc/system

               
               2.1 hme interface = 10MB full duplex
   
                   set hme:hme_adv_autoneg_cap=0
                   set hme:hme_adv_100T4_cap=0
                   set hme:hme_adv_100fdx_cap=0
                   set hme:hme_adv_100hdx_cap=0
                   set hme:hme_adv_10fdx_cap=1
                   set hme:hme_adv_10hdx_cap=0
   
              2.2 hme interface = 10MB half duplex
   
                   set hme:hme_adv_autoneg_cap=0
                   set hme:hme_adv_100T4_cap=0
                   set hme:hme_adv_100fdx_cap=0
                   set hme:hme_adv_100hdx_cap=0
                   set hme:hme_adv_10fdx_cap=0
                   set hme:hme_adv_10hdx_cap=1
   
               2.3 hme interface = 100MB full duplex
   
                   set hme:hme_adv_autoneg_cap=0
                   set hme:hme_adv_100T4_cap=0
                   set hme:hme_adv_100fdx_cap=1
                   set hme:hme_adv_100hdx_cap=0
                   set hme:hme_adv_10fdx_cap=0
                   set hme:hme_adv_10hdx_cap=0
   
              2.4 hme interface = 100MB half duplex
   
                   set hme:hme_adv_autoneg_cap=0
                   set hme:hme_adv_100T4_cap=0
                   set hme:hme_adv_100fdx_cap=0
                   set hme:hme_adv_100hdx_cap=1
                   set hme:hme_adv_10fdx_cap=0
                   set hme:hme_adv_10hdx_cap=0
   	

4. As for 2 or more hme cards, instance should be set up independently.

                   # ndd -set /dev/hme instance 0
                     parameters for hme0
   
                   # ndd -set /dev/hme instance 1
                     parameters for hme1
   	

5. /etc/init.d/inetinit or /etc/rc2.d/S69inet

   	# Set configurable parameters
   	ndd -set /dev/tcp tcp_old_urp_interpretation 1
   	# Set full duplex hme0
   	ndd -set /dev/hme instance 0
   	ndd -set /dev/hme adv_100fdx_cap 1
   	ndd -set /dev/hme adv_autoneg_cap 0
   	# Set Max TCP buffer
   	ndd -set /dev/tcp tcp_xmit_hiwat 65535
   	ndd -set /dev/tcp tcp_recv_hiwat 65535
   	ndd -set /dev/tcp tcp_cwnd_max 65535
   	#
   	

6. To set /dev/hme to full duplex:

   	#! /bin/sh
   	# Set /dev/hme to full duplex
   	
   	ndd /dev/hme link_status > /dev/null 2>&1
   	status=$?
   	if [ $status -eq 0 ]; then
   		echo "Setting hme to full duplex"
   		ndd -set /dev/hme adv_autoneg_cap 0
   		ndd -set /dev/hme adv_100hdx_cap 0
   		ndd -set /dev/hme adv_100fdx_cap 1
   		#ndd -set /dev/hme adv_autoneg_cap 1
   		link_mode=`ndd /dev/hme link_mode`
   		#if [ "$link_mode" -eq "0" ]; then
   		#		echo "Error, link_mode == $link_mode, should equal 1"
   		#fi
   	else
   		echo "No hme, so no full duplex"
   	fi
   	

7. To set all hme to Full Duplex.

   	#!/bin/ksh
   	NDD="/usr/sbin/ndd -set /dev/hme"
   	TRUE=1
   	FALSE=0
   	autoneg=0
   	speed=100
   	#
   	print "Setting the Ethernet-Adapters to 100MB/s Full/Duplex"
   	
   	for instance in 1 2 3
   	do
   		echo "Setting card # $instance to $speed Mb/S Full Duplex"
   		# Only use internal Xcever
   		$NDD instance $instance
   		$NDD use_int_xcvr $TRUE
   		$NDD adv_100T4_cap $FALSE
   		sleep 2
   		$NDD adv_100fdx_cap $TRUE
   		sleep 2
   		$NDD adv_100hdx_cap $FALSE
   		sleep 2
   		$NDD adv_10fdx_cap $FALSE
   		sleep 2
   		$NDD adv_10hdx_cap $FALSE
   		sleep 2
   		$NDD adv_autoneg_cap $autoneg
   	done
   	echo "all Adapters done...\n"
   	exit
