test_l2xc module¶
-
class
test_l2xc.TestL2xc(methodName='runTest')¶ Bases:
framework.VppTestCaseL2XC Test Case
-
classmethod
create_host_lists(count)¶ Method to create required number of MAC and IPv4 addresses. Create required number of host MAC addresses and distribute them among interfaces. Create host IPv4 address for every host MAC address too.
Parameters: count – Number of hosts to create MAC and IPv4 addresses for.
-
create_stream(src_if, packet_sizes, packets_per_burst)¶ Create input packet stream for defined interface.
Parameters: - src_if (object) – Interface to create packet stream for.
- packet_sizes (list) – List of required packet sizes.
- packets_per_burst (int) – Number of packets in burst.
Returns: Stream of packets.
-
run_l2xc_test(pkts_per_burst)¶ L2XC test
-
setUp()¶ Clear trace and packet infos before running each test.
-
classmethod
setUpClass()¶ Perform standard class setup (defined by class method setUpClass in class VppTestCase) before running the test case, set test case related variables and configure VPP.
Variables: - hosts_nr (int) – Number of hosts to be created.
- dl_pkts_per_burst (int) – Number of packets in burst for dual-loop test.
- sl_pkts_per_burst (int) – Number of packets in burst for single-loop test.
-
tearDown()¶ Show various debug prints after each test.
-
test_l2xc_dl()¶ L2XC dual-loop test

- 64B, 512B, 1518B, 9018B (ether_size) burst of 257 packets per interface
-
test_l2xc_sl()¶ L2XC single-loop test
- Test scenario:
- config
- 2 pairs of 2 interfaces, l2xconnected
- sending l2 eth packets between 4 interfaces
- 64B, 512B, 1518B, 9018B (ether_size) burst of 2 packets per interface
-
verify_capture(pg_if, capture)¶ Verify captured input packet stream for defined interface.
Parameters: - pg_if (object) – Interface to verify captured packet stream for.
- capture (list) – Captured packet stream.
