class test_gtpu.TestGtpu(*args)¶

Bases: template_bd.BridgeDomain, framework.VppTestCase

GTPU Test Case

classmethod add_del_mcast_tunnels_load(is_add)¶: add or del tunnels to test gtpu stability

classmethod add_del_shared_mcast_dst_load(is_add)¶: add or del tunnels sharing the same mcast dst to test gtpu ref_count mechanism

classmethod add_mcast_tunnels_load()¶

classmethod add_shared_mcast_dst_load()¶

check_encapsulation(pkt, vni, local_only=False, mcast_pkt=False)¶: Verify the encapsulation

classmethod create_gtpu_flood_test_bd(teid, n_ucast_tunnels)¶

decapsulate(pkt)¶: Decapsulate the original payload frame by removing GTPU header

classmethod del_mcast_tunnels_load()¶

classmethod del_shared_mcast_dst_load()¶

encap_mcast(pkt, src_ip, src_mac, vni)¶: Encapsulate the original payload frame by adding GTPU header with its UDP, IP and Ethernet fields

encapsulate(pkt, vni)¶: Encapsulate the original payload frame by adding GTPU header with its UDP, IP and Ethernet fields

ip_range(start, end)¶: range of remote ip’s

classmethod setUpClass()¶: Perform class setup before running the testcase Remove shared memory files, start vpp and connect the vpp-api

tearDown()¶: Show various debug prints after each test

classmethod tearDownClass()¶: Perform final cleanup after running all tests in this test-case

test_encap()¶: Encapsulation test Send frames from pg1 Verify receipt of encapsulated frames on pg0

test_mcast_flood()¶: Multicast flood test Send frames from pg2 Verify receipt of encapsulated frames on pg0

test_ucast_flood()¶: Unicast flood test Send frames from pg3 Verify receipt of encapsulated frames on pg0
