+<section>
+<title>My box has more than one Sun Ethernet device. Why do they all have the
+same MAC address and how do I fix it?</title>
+<body>
+
+<p>
+First, the reason they all they all have the same setting is due to a value in
+OpenBoot PROM (OBP). The story goes that in times past, it was assumed that if
+a host had multiple interfaces, the interfaces would not reside on the same
+Ethernet and therefore having the MAC address unique to a machine rather than
+to a NIC wouldn't be a problem. As time went on and different technologies
+developed, the opposite was proven.
+</p>
+
+<p>
+As for fixing the issue, there are two ways to it; from OBP and from Linux. The
+OBP variable <c>local-mac-address?</c> controls this behavior. The following
+commands will help you to determine what <c>local-mac-address?</c> is set to:
+</p>
+
+<pre caption="View local-mac-address? setting from OBP">
+ok <i>printenv local-mac-address?</i>
+local-mac-address? =  false
+</pre>
+
+<pre caption="View local-mac-address? setting from Linux">
+# <i>eeprom local-mac-address?</i>
+local-mac-address?=false
+</pre>
+
+<p>
+As you'll notice from the samples above, <c>local-mac-address?</c> is set to
+<b>false</b>. This will cause all interfaces on a SPARC to use the same MAC
+address. To change this behavior, use either of the commands below (depending
+on whether you do it from OBP or Linux):
+</p>
+
+<pre caption="Set local-mac-address? from OBP">
+ok <i>setenv local-mac-address?=true</i>
+local-mac-address? =  true
+</pre>
+
+<pre caption="Set local-mac-address? from Linux">
+# <i>eeprom local-mac-address?=true</i>
+</pre>
+
+<p>
+Note that you may need to reboot to see the changes take affect.
