This assumes you can physically add the interface (most commonly true in a virtualised environment). Have tried an tested this procedure on various versions of Vyatta router, all running on VMware environments. Only issue has been very occasionally the NIC can&#039;t be added without a reboot, though I&#039;d recommend doing this outside of peak traffic hours, and to put a snapshot in place 1st!<br /> <br /> # Login to Vyatta make sure the running config has been saved<br /> #* &lt;code&gt;configure&lt;/code&gt;<br /> #* &lt;code&gt;save&lt;/code&gt;<br /> #* &lt;code&gt;exit&lt;/code&gt;<br /> # Go into root<br /> # Check current NIC&#039;s<br /> #* &lt;code&gt; ls -l /sys/class/net/ &lt;/code&gt;<br /> # Add NIC via VMware<br /> #* Should be VMXNET3<br /> # Find PCI Bus ID for an existing network card<br /> #* &lt;code&gt; dmesg | grep vmxnet &lt;/code&gt;<br /> # Rescan for network devices<br /> #* EG &lt;code&gt; echo &quot;1&quot; &gt; /sys/class/pci_bus/0000:03/device/rescan &lt;/code&gt;<br /> # Check new device has been found<br /> #* &lt;code&gt; dmesg | grep vmxnet &lt;/code&gt;<br /> #* &lt;code&gt; ls -l /sys/class/net/ &lt;/code&gt;<br /> # Exit out of root<br /> #* &lt;code&gt; exit &lt;/code&gt;<br /> # Get the MAC address of the new interface (replace &lt;code&gt;eth2&lt;/code&gt; as required)<br /> #* EG &lt;code&gt; show interfaces ethernet eth2&lt;/code&gt;<br /> # Enter config mode<br /> #* &lt;code&gt; configure &lt;/code&gt;<br /> # Add MAC address to config<br /> #* EG &lt;code&gt; set interfaces ethernet eth2 hw-id 00:50:56:80:7d:8a &lt;/code&gt;<br /> # Commit/apply MAC address config<br /> #* &lt;code&gt; commit &lt;/code&gt;<br /> #* The NIC&#039;s MAC address needs to be applied in the config before any other interface config (otherwise it&#039;ll fail to commit).<br /> #* An error of &lt;code&gt; not setting autoneg &lt;/code&gt; is sometimes received and isn&#039;t a problem<br /> # Configure other basic settings<br /> #* EG &lt;code&gt; set interfaces ethernet eth2 duplex &#039;auto&#039; &lt;/code&gt;<br /> #* EG &lt;code&gt; set interfaces ethernet eth2 speed &#039;auto&#039; &lt;/code&gt;<br /> # Commit/apply changes<br /> #* &lt;code&gt; commit &lt;/code&gt;<br /> <br /> The new interface can now be configured as normal (remove the snapshot if you put one in place), for example...<br /> <br /> set interfaces ethernet eth2 description &quot;NewNIC for stuff&quot;<br /> set interfaces ethernet eth2 address 192.168.10.0/24<br /> <br /> <br /> [[Category:Vyatta]]</div>
