+Networking Interface Attach / Detach
+====================================
 
+The Attach / Detach subdomain should cover all the possible scenarios where we
+can loose connection between NIC`s, this is no matter the kind of hardware or
+virtual environment that we are using for our testing. In some cases we want
+to know how is the NIC driver going to work with a simple unplug action.

+:Test ID: NET_IN_AT_DA_07
+:Test Title: Detach and attach on instances with E1000 interfaces (hardware).
+:Tags: Interface Attach/Detach
+
+~~~~~~~~~~~~~~~~~~
+Testcase Objective
+~~~~~~~~~~~~~~~~~~
+
+Verify interface detach and attach on instances with E1000 interfaces over
+hardware.
+
+~~~~~~~~~~~~~~~~~~~
+Test Pre-Conditions
+~~~~~~~~~~~~~~~~~~~
+
+a) Instances created with e1000 network driver.
+
+~~~~~~~~~~
+Test Steps
+~~~~~~~~~~
+
+1. Get subnet ID for created network.
+
+   ::
+
+   $ openstack network list
+
+
+
+2. From subnet get por ID.
+
+   ::
+
+   $ openstack port list
+
+
+3. Detach the port by using the following command line:
+
+   ::
+
+      $ openstack stack port set <port id> --device none
+
+4. Attach the port back.
+
+   ::
+
+     $ openstack port set <port id> --device <vm id>
+
+5. Perform VM operations such as stop, start/pause/Unpause Suspend/Resume and
+migration.
+
+~~~~~~~~~~~~~~~~~
+Expected Behavior
+~~~~~~~~~~~~~~~~~
+
+After the detach / attach operation, our VM should be alive and capable of
+performing all kind or regular actions.
