In this example we will configure interface qfe1 with the an IP of 192.168.1.1 255.255.255.0 and set the speed to 100 full duplex.<\/span><\/p>\n

Bring up the Interface<\/strong><\/span><\/p>\n

To bring up and plumb the interface, we first need to type the following, (change the IP to yours)<\/span><\/p>\n

ifconfig qfe1 plumb
ifconfig qfe1 192.168.1.1 netmask 255.255.255.0 up<\/span>
<\/span><\/pre>\n
Update the <\/span>\/etc\/netmasks<\/span> file with the network address and subnet mask, if not already present (the required line is below),<\/span><\/p>\n
192.168.1.0           255.255.255.0<\/span>
<\/span><\/pre>\n
For the new interface , first edit the \/etc\/hosts file and create a new entry. The space should be a tab.<\/span><\/p>\n
192.168.1.1            solarisserver-qfe1<\/span>
<\/span><\/pre>\n
Now create a new file <\/span>\/etc\/hostname.qfe1<\/span> and add the entry<\/span><\/p>\n
solarisserver-qfe1<\/span>
<\/span><\/pre>\n
To do the above but using less effort (and lines) try the following,<\/span><\/p>\n
ifconfig qfe1 plumb ; ifconfig qfe1 192.168.1.1 netmask 255.255.255.0 up 
echo \"192.168.1.0\\t255.255.255.0\" >> \/etc\/netmasks
echo \"192.168.1.1\\t\"`hostname`-qfe1 >> \/etc\/hosts
echo `hostname`-qfe1 > \/etc\/hostname.qfe1<\/span>
<\/span><\/pre>\n
Set Duplex<\/strong><\/span><\/p>\n
ndd -set \/dev\/qfe instance 1 <\/span>
<\/span>ndd -set \/dev\/qfe adv_100fdx_cap 1<\/span>
<\/span><\/pre>\n
Then to make the change permanent add to <\/span>\/etc\/system<\/span>
<\/span><\/p>\n
set \/dev\/qfe1 adv_100fdx_cap 1<\/span>
<\/span><\/pre>\n
Below is a reference to the difference abbreviations : <\/span><\/p>\n
instance 1 = port instance 1
adv          = advertise
cap          = capability
1             = enabled
0             = disabled
<\/span><\/pre>\n
Check the interface <\/strong><\/span><\/p>\n
Check the IP address and status of the interface <\/span><\/p>\n
ifconfig -a
<\/span><\/pre>\n
Set the interface we are going to check,<\/span><\/p>\n
ndd -set \/dev\/qfe instance 1
<\/span><\/pre>\n
To check the link, (reply of 1 = LED is active, 0 = Line is dead)<\/span><\/p>\n
ndd -get \/dev\/qfe link_status
<\/span><\/pre>\n
To check the negotiated speed,<\/span><\/p>\n
     1=100mbit for qfe & hme, 1 Gbit for ge.
     0=10mbit for qfe & hme, 500 mbit for ge. <\/span><\/p>\n
ndd -get \/dev\/qfe link_speed<\/span>
<\/span><\/pre>\n
To check link mode, (1= full-duplex, 0 = half-duplex)<\/span><\/p>\n
ndd -get \/dev\/qfe link_mode<\/span>
<\/span><\/pre>\n
Remove the Interface<\/strong><\/span><\/p>\n
Disable interface qfe1<\/span><\/p>\n
ifconfig qfe1 down<\/span>
<\/span><\/pre>\n
Remove the interface qfe1<\/span><\/p>\n
ifconfig qfe1 unplum<\/span>b
