7.3.9. L2XC Ethernet Switching¶
7.3.9.1. eth2p-eth-l2xcbase-eth-2vhost-1vm-func¶
L2 cross-connect test cases
- [Top] Network Topologies: TG=DUT=VM 3-node topology with VM and double parallel links.
- [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4; Eth-IPv6-ICMPv6 for L2 switching of IPv6 use. Both apply to all links.
- [Cfg] DUT configuration: DUT1 is configured with L2 cross-connect (L2XC) switching.
- [Ver] TG verification: Test ICMPv4 (or ICMPv6) Echo Request packets are sent in both directions by TG on links to DUT1 via VM; on receive TG verifies packets for correctness and their IPv4 (IPv6) src-addr, dst-addr and MAC addresses.
- [Ref] Applicable standard specifications:
| Name | Documentation | Status |
|---|---|---|
| TC01: DUT with two L2XCs switches ICMPv4 between TG and local VM links | [Top] TG=DUT=VM. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT configure two L2 cross-connects (L2XC), each with one untagged interface to TG and untagged i/f to local VM over vhost-user. [Ver] Make TG send ICMPv4 Echo Reqs in both directions between two of its i/fs to be switched by DUT to and from VM; verify all packets are received. [Ref] |
PASS |
| TC02: DUT with two L2XCs switches ICMPv6 between TG and local VM links | [Top] TG=DUT=VM. [Enc] Eth-IPv6-ICMPv6. [Cfg] On DUT configure two L2 cross-connects (L2XC), each with one untagged i/f to TG and untagged i/f to local VM over vhost-user. [Ver] Make TG send ICMPv6 Echo Reqs in both directions between two of its i/fs to be switched by DUT to and from VM; verify all packets are received. [Ref] |
PASS |
7.3.9.2. eth2p-eth-l2xcbase-func¶
L2 cross-connect test cases
- [Top] Network Topologies: TG-DUT1-DUT2-TG 3-node circular topology with single links between nodes.
- [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4; Eth-IPv6-ICMPv6 for L2 switching of IPv6 use. Both apply to all links.
- [Cfg] DUT configuration: DUT1 and DUT2 are configured with L2 cross-connect (L2XC) switching.
- [Ver] TG verification: Test ICMPv4 (or ICMPv6) Echo Request packets are sent in both directions by TG on links to DUT1 and DUT2; on receive TG verifies packets for correctness and their IPv4 (IPv6) src-addr, dst-addr and MAC addresses.
- [Ref] Applicable standard specifications:
| Name | Documentation | Status |
|---|---|---|
| TC01: DUT1 and DUT2 with L2XC switch ICMPv4 between two TG links | [Top] TG-DUT1-DUT2-TG. [Enc] Eth-IPv4-ICMPv4. [Cfg] On DUT1 and DUT2 configure L2 cross-connect (L2XC), each with one interface to TG and one Ethernet interface towards the other DUT. [Ver] Make TG send ICMPv4 Echo Req in both directions between two of its interfaces to be switched by DUT1 and DUT2; verify all packets are received. [Ref] |
PASS |
| TC02: DUT1 and DUT2 with L2XC switch ICMPv6 between two TG links | [Top] TG-DUT1-DUT2-TG. [Enc] Eth-IPv6-ICMPv6. [Cfg] On DUT1 and DUT2 configure L2 cross-connect (L2XC), each with one interface to TG and one Ethernet interface towards the other DUT. [Ver] Make TG send ICMPv6 Echo Req in both directions between two of its interfaces to be switched by DUT1 and DUT2; verify all packets are received. [Ref] |
