  99 |applicability | Test can be configured with different flavors, vNIC type     |
 100 |              | and packet sizes. Default values exist as specified above.   |
 101 |              | The vNIC type and flavor MUST be specified by the user.      |
 102 |              |                                                              |
 103 +--------------+--------------------------------------------------------------+
 104 |pre-test      | The vTC has been successfully instantiated and configured.   |
 105 |              | The user has correctly assigned the values to the deployment |
 106 |              |  configuration parameters.                                   |
 107 |              |                                                              |
 108 |              | - Multicast traffic MUST be enabled on the network.          |
 109 |              |      The Data network switches need to be configured in      |
 110 |              |      order to manage multicast traffic.                      |
 111 |              |      Installation and configuration of smcroute is required  |
 112 |              |      before to run the test case.                            |
 113 |              |      (For further instructions please refer to the ApexLake  |
 114 |              |      documentation).                                         |
 115 |              | - In the case of SR-IOV vNICs use, SR-IOV compatible NICs    |
 116 |              |      must be used on the compute node.                       |
 117 |              | - Yarsdtick needs to be installed on a host connected to the |
 118 |              |      data network and the host must have 2 DPDK-compatible   |
 119 |              |      NICs. Proper configuration of DPDK and DPDK pktgen is   |
 120 |              |      required before to run the test case.                   |
 121 |              |      (For further instructions please refer to the ApexLake  |

 128 |step 1        | The noisy neighbours are deployed as required by the user.   |
 129 |              |                                                              |
 130 +--------------+--------------------------------------------------------------+
 131 |step 2        | The vTC is deployed, according to the configuration provided |
 132 |              | by the user.                                                 |
 133 |              |                                                              |
 134 +--------------+--------------------------------------------------------------+
 135 |step 3        | The vTC is correctly deployed and configured as necessary.   |
 136 |              | The initialization script has been correctly executed and    |
 137 |              | the vTC is ready to receive and process the traffic.         |
 138 |              |                                                              |
 139 +--------------+--------------------------------------------------------------+
 140 |step 4        | Test case is executed with the selected parameters:          |
 141 |              | - vTC flavor                                                 |
 142 |              | - vNIC type                                                  |
 143 |              | A constant rate traffic is sent to the vTC for 10 seconds.   |
 144 |              |                                                              |
 145 +--------------+--------------------------------------------------------------+
 146 |step 5        | The vTC instance tags all the packets and sends them back to |
 147 |              | the packet generator for 10 seconds.                         |
 148 |              |                                                              |
 149 |              | The framework checks if the packet generator receives back   |
 150 |              | all the packets with the correct tag from the vTC.           |
 151 |              |                                                              |
 152 +--------------+--------------------------------------------------------------+
 153 |test verdict  |  The vTC is deemed to be successfully instantiated if all    |
 154 |              |  packets are sent back with the right tag as requested,      |
 155 |              |  else it is deemed DoA (Dead on arrival)                     |
 156 |              |                                                              |
