7.3.14. Tap Interface¶
7.3.14.1. api-crud-tap-func¶
Tap Interface CRUD Tests
- [Top] Network Topologies: TG=DUT1 2-node topology with two links between nodes.
- [Enc] Packet Encapsulations: No packet sent.
- [Cfg] DUT configuration: Add/Modify/Delete linux-TAP on DUT1.
- [Ver] Verification: Check dump of tap interfaces for correctness.
- [Ref] Applicable standard specifications:
| Name | Documentation | Status |
|---|---|---|
| TC01: Tap Interface Modify And Delete | [Top] TG-DUT1-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] Set two TAP interfaces. [Ver] Verify that TAP interface can be modified, deleted, and no other TAP interface is affected. |
PASS |
7.3.14.2. eth2p-eth-l2bdbasemaclrn-eth-2tap-func¶
Tap Interface Traffic Tests
- [Top] Network Topologies: TG=DUT1 2-node topology with two links between nodes.
- [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4.
- [Cfg] DUT configuration: DUT1 and DUT2 are configured with L2 bridge-domain (L2BD) MAC learning enabled; Split Horizon Groups (SHG) are set depending on test case; Namespaces (NM) are set on DUT1 with attached linux-TAP.
- [Ver] TG verification: Test ICMPv4 Echo Request packets are sent by TG on link to DUT1; On receipt TG verifies packets for correctness and their IPv4 src-addr, dst-addr, and MAC addresses.
- [Ref] Applicable standard specifications:
| Name | Documentation | Status |
|---|---|---|
| TC01: Tap Interface Simple BD | [Top] TG-DUT1-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT1 configure two L2BD with two if’s for each L2BD with MAC learning and one L2BD joining two linux-TAP interfaces created by VPP located in namespace. [Ver] Packet sent from TG is passed through all L2BD and received back on TG. Then src_ip, dst_ip and MAC are checked. |

| Name | Documentation | Status |
|---|---|---|
| TC01: Tap Interface BD - Different Split Horizon | [Top] TG-DUT1-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT1 configure one if into L2BD with MAC learning. Add two TAP interfaces into this L2BD and assign them different SHG. Setup two namespaces and assign two linux-TAP interfaces to it respectively. [Ver] Packet is sent from TG to both linux-TAP interfaces and reply is checked. Ping from First linux-TAP to another should pass. |
PASS |
| TC02: Tap Interface BD - Same Split Horizon | [Top] TG-DUT1-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT1 configure one if into L2BD with MAC learning. Add two TAP interfaces into this L2BD and assign them same SHG. Setup two namespaces and assign two linux-TAP interfaces to it respectively. [Ver] Packet is sent from TG to both linux-TAP interfaces and reply is checked. Ping from First linux-TAP to another should fail. |

| TC01: Tap Interface IP Ping Without Namespace | [Top] TG-DUT1-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT1 configure two interface addresses with IPv4 of which one is TAP interface ( dut_to_tg_if and TAP ). and one is linux-TAP. [Ver] Packet sent from TG gets to the destination and ICMP-reply is received on TG. |
PASS |
