 Now let's configure the switch and point it to the test server.
 It can be done in the same way as connecting the switch to any controller.

 For example, in this case, all the multicast failed because we don't have three ports, the test L3VPN failed as well, and that is a bug of the current build.
 The **PacketInSrcMac** Miss failed because Mac learning is not enabled.

 .. tip::
-	OFTest can't successfully delete all groups using an OF message, because of that some tests interfere with others.
-	If the results seem suspicious, **erase the flow tables and group tables** and run the test alone.
