-====== Etherstubs / Virtual Switches ======
-===== Introduction =====
-Etherstubs seem to confuse some people. Things usually get  cleared up when I compare the to vSwitches.
-Take the following example:\\
-{{ :snipets:solaris:etherstub-example.png?nolink|}}
-You have:
-  * 1 reverse proxy to filter traffic and do loadbalancing
-  * 2 applications servers
-  * 2 database servers
-Say you run each component in either zone or KVM instance,
-you can then give each a vnic that is linked to your main network interface.
-But will put more traffic on your physical switch and also open up some security issues. You could ofcourse use VLAN's but that again adds more administrative complexity.
-To solve this you can use an etherstub with vnics for the database and application servers. The proxy will also have a vnic on the etherstub and one on the physical interface.
-This approuce will:
-  * **reduce the need for VLAN's,** this elminitating the extra complexity of your physical network.
-  * **eliminate the traffic on the physical switch**
-  * **security benifits**, the backend servers are not connected to the physical network.
-Bellow I'll give some examples on how to create an etherstub and how to add vnics to it.
