===Using Ethernet===
|}
The Linux OS used on the RZ boards brings up the Ethernet interface automatically during startup. This is done by the "systemd-networkd" service that is automatically start each time you boot. If your RZ board is connected to a network that has a DHCP server, the board will obtain an IP address from it automatically. You just need to execute ‘ifconfig’ to see what the assigned IP address is.
<pre>
$ ifconfig
</pre>
 
In some scenarios the Ethernet interface may not be active (meaning "systemd-networkd" is not started or used). In this case, you would enter the follow to enable it and use the ifconfig to show what interfaces are active.
<pre>
$ ifconfig
$ ifconfig eth0 up
$ ifconfig
</pre>
 
After the interface is enabled, you will need to assign an IP address. You can either do that manually or use DHCP if it is available on the network.
 
Manual:
<pre>
$ ifconfig eth 1925.168.0.55
</pre>
 
DHCP:
<pre>
$ udhcpc -i eth0
</pre>
 
NOTE: After ‘ifconfig eth0 up’, you may notice that it already has an IPv6 address even though it doesn’t have a IPv4 address yet. No one really assigned that IPv6 address. In IPv6, you can always assign yourself a 'link local' address by just taking your MAC address and putt putting "fe80" at the beginning and "fe00" in the middle.
