|test case id | OPNFV_YARDSTICK_TC0020_Virtual Traffic Classifier |
| | Instantiation Test |
| | |
+--------------+--------------------------------------------------------------+
|metric | Failure |
| | |
+--------------+--------------------------------------------------------------+
|test purpose | To verify that a newly instantiated vTC is 'alive' and |
| | functional and its instantiation is correctly supported by |
| | the infrastructure. |
| | |
+--------------+--------------------------------------------------------------+
|configuration | file: opnfv_yardstick_tc020.yaml |
| | |
| | vnic_type: type of VNIC to be used. |
| | Allowed values are: |
| | - normal: for default OvS port configuration |
| | - direct: for SR-IOV port configuration |
| | Default value: None |
| | |
| | vtc_flavor: OpenStack flavor to be used for the vTC |
| | Default available values are: m1.small, m1.medium, |
| | and m1.large, but the user can create his/her own |
| | flavor and give it as input |
| | Default value: None |
| | |
| | vlan_sender: vlan tag of the network on which the vTC will |
| | receive traffic (VLAN Network 1). |
| | Allowed values: range (1, 4096) |
| | |
| | vlan_receiver: vlan tag of the network on which the vTC |
| | will send traffic back to the packet generator |
| | (VLAN Network 2). |
| | Allowed values: range (1, 4096) |
| | |
| | default_net_name: neutron name of the defaul network that |
| | is used for access to the internet from the vTC |
| | (vNIC 1). |
| | |
| | default_subnet_name: subnet name for vNIC1 |
| | (information available through Neutron). |
| | |
| | vlan_net_1_name: Neutron Name for VLAN Network 1 |
| | (information available through Neutron). |
| | |
| | vlan_subnet_1_name: Subnet Neutron name for VLAN Network 1 |
| | (information available through Neutron). |
| | |
| | vlan_net_2_name: Neutron Name for VLAN Network 2 |
| | (information available through Neutron). |
| | |
| | vlan_subnet_2_name: Subnet Neutron name for VLAN Network 2 |
| | (information available through Neutron). |
| | |

|test tool | DPDK pktgen |
| | |
| | DPDK Pktgen is not part of a Linux distribution, |
| | hence it needs to be installed by the user. |
| | |

+--------------+--------------------------------------------------------------+
|applicability | Test can be configured with different flavors, vNIC type |
| | and packet sizes. Default values exist as specified above. |
| | The vNIC type and flavor MUST be specified by the user. |
| | |
+--------------+--------------------------------------------------------------+
|pre-test | The vTC has been successfully instantiated and configured. |
| | The user has correctly assigned the values to the deployment |
| | configuration parameters. |
| | |
| | - Multicast traffic MUST be enabled on the network. |
| | The Data network switches need to be configured in |
| | order to manage multicast traffic. |
| | Installation and configuration of smcroute is required |
| | before to run the test case. |
| | (For further instructions please refer to the ApexLake |
| | documentation). |
| | - In the case of SR-IOV vNICs use, SR-IOV compatible NICs |
| | must be used on the compute node. |
| | - Yarsdtick needs to be installed on a host connected to the |
| | data network and the host must have 2 DPDK-compatible |
| | NICs. Proper configuration of DPDK and DPDK pktgen is |
| | required before to run the test case. |
| | (For further instructions please refer to the ApexLake |
| | documentation). |
| | |
+--------------+--------------------------------------------------------------+
|test sequence | Description and expected results |
| | |
+--------------+--------------------------------------------------------------+
|step 1 | The vTC is deployed, according to the configuration provided |
| | by the user. |
| | |
+--------------+--------------------------------------------------------------+
|step 2 | The vTC is correctly deployed and configured as necessary. |
| | The initialization script has been correctly executed and |
| | the vTC is ready to receive and process the traffic. |
| | |
+--------------+--------------------------------------------------------------+
|step 3 | Test case is executed with the parameters specified by the |
| | the user: |
| | - vTC flavor |
| | - vNIC type |
| | A constant rate traffic is sent to the vTC for 10 seconds. |
| | |
+--------------+--------------------------------------------------------------+
|step 4 | The vTC instance tags all the packets and sends them back to |
| | the packet generator for 10 seconds. |
| | |
| | The framework checks that the packet generator receives |
| | back all the packets with the correct tag from the vTC. |
| | |
+--------------+--------------------------------------------------------------+
|test verdict | The vTC is deemed to be successfully instantiated if all |
| | packets are sent back with the right tag as requested, |
| | else it is deemed DoA (Dead on arrival) |
| | |
+--------------+--------------------------------------------------------------+
