SUMMARY: SunFire V240 - lock ethernet interface

Thanks to Stella Kong for the below reply:-

I used option 2 and it worked fine.

Hi Brett:

As a document Sun had provided (ID70401) there is 2 solutions:

1. Create script in /etc/rc2.d to force it to set it to 100fdx everytime
system when system reboot.

Create script /etc/rc2.d/S68net_tune

#!/sbin/sh
# /etc/rc2.d/S68net-tune
PATH=/usr/bin:/usr/sbin
echo "Implementing Solaris ndd Tuning Changes "
# bge-Interfaces
# Force bge0 to 100fdx autoneg off
ndd -set /dev/bge0 adv_1000fdx_cap 0
ndd -set /dev/bge0 adv_1000hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_10fdx_cap 0
ndd -set /dev/bge0 adv_10hdx_cap 0
ndd -set /dev/bge0 adv_autoneg_cap 0

Make the script executable:
# chmod 755 /etc/rc2.d/S68net_tune

After the script is run, you will see that the nic is set to 100fdx
autoneg
off.

2. 

BGE.CONF
To force bge interface to 100mbps full duplex, put the following entries
in
/platform/sun4u/kernel/drv/bge.conf
A reboot is required for this method.

adv_1000fdx_cap=0;
adv_1000hdx_cap=0;
adv_100fdx_cap=1;
adv_100hdx_cap=0;
adv_10fdx_cap=0;
adv_10hdx_cap=0;
adv_autoneg_cap=0;

NOTE: Using bge.conf will force all instances of bge to the speed/duplex
specified in the file. Use ndd to force individual instances if for
example
bge0 needs to be 10hdx and bge1 needs to be 100fdx.

Regards,
Stella
