-    in front of the MAC address of the management interface. If a switch has been provisioned
-    by MAAS correctly, you should be able to find DPID information in `/root/connect` on each switch.
-    Search for the following line:

 ### Complete
 
 This step is complete when each compute node can ping the fabric IP address of all the other nodes.
