To prevent issues with auto negotiation, forced both the network switch and the system’s NIC cards to 100 Mbps, full
duplex.
Determined which interfaces are available:
# ifconfig -a
Configured on-line (use only the interfaces found on the system):
hme:
# ndd -set /dev/hme instance 0
# ndd -set /dev/hme adv_100fdx_cap 1
# ndd -set /dev/hme adv_autoneg_cap 0
qfe:
# ndd -set /dev/qfe instance 0
# ndd -set /dev/qfe adv_100fdx_cap 1
# ndd -set /dev/qfe adv_autoneg_cap 0
eri:
# ndd -set /dev/eri instance 0
# ndd -set /dev/eri adv_100fdx_cap 1
# ndd -set /dev/eri adv_autoneg_cap 0
ce:
# ndd -set /dev/ce instance 0
# ndd -set /dev/ce link_master 0
# ndd -set /dev/ce adv_1000fdx_cap 0
# ndd -set /dev/ce adv_1000hdx_cap 0
# ndd -set /dev/ce adv_100fdx_cap 1
# ndd -set /dev/ce adv_100hdx_cap 0
# ndd -set /dev/ce adv_10fdx_cap 0
# ndd -set /dev/ce adv_10hdx_cap 0
# ndd -set /dev/ce adv_autoneg_cap 0
Configured for reboot (use only the interfaces found on the system):
hme, qfe & eri:
# vi /etc/system (ensure there are no blank lines)
* Force hme into 100 Mbps full duplex mode
set hme:hme_adv_100fdx_cap=1
* Don’t negotiate operation mode with the network hub
set hme:hme_adv_autoneg_cap=0
* Force qfe into 100 Mbps full duplex mode
set qfe:qfe_adv_100fdx_cap=1
* Don’t negotiate operation mode with the network hub
set qfe:qfe_adv_autoneg_cap=0
* Force eri into 100 Mbps full duplex mode
set eri:adv_100fdx_cap=1
* Don’t negotiate operation mode with the network hub
set eri:adv_autoneg_cap=0
ce:
# vi /etc/rc2.d/S99net-tune
#!/sbin/sh
# Set NIC to 100 Mbps full duplex
ndd -set /dev/ce instance 0
ndd -set /dev/ce link_master 0
ndd -set /dev/ce adv_1000fdx_cap 0
ndd -set /dev/ce adv_1000hdx_cap 0

ndd -set /dev/ce adv_10fdx_cap 0
ndd -set /dev/ce adv_10hdx_cap 0
ndd -set /dev/ce adv_autoneg_cap 0
exit 0
# chmod 700 /etc/rc2.d/S99net-tune
Confirmed settings:
hme, qfe and eri:
# ifconfig -a
ce:
# netstat -k ce0 | grep link_speed
link_speed 100 link_duplex 2 link_asmpause 0 link_pause 0
link_speed – speed in Mbps
link_duplex – 1 half duplex, 2 full duplex, 0 down
