+# Lines beginning with the word "auto" are used to identify the physical interfaces to be brought up
+# when ifup is run with the -a option. (This option is used by the system boot scripts.) Physical
+# interface names should follow the word "auto" on the same line
+
+# Lines beginning with the word "allow-hotplug" have same effects as lines beginning with "auto".
+# But the interface will be brought up only if connected to the network.
