@vallabh78 Good suggestion. Refactored in commit 8349da3 to reuse

can we move the evpn route type 5 verification to verify_base_setup_bgw and call it in the testcase? In that way we can use it in other testcases. |

We need to add this bgp cache: bgp_info = vxlan_obj.get_bgp_underlay_info_cached() and pass it into l3vni_sonic_bgw_dci and l3vni_frr_bgw_dci in the config_bgw_nodes function. Without this it caused the script to fail and script was unable to configure any BGP related config. |
…config_bgw_nodes Address PR review comments: 1. Move EVPN Type-5 route verification into verify_base_setup_bgw as a new 'evpn_type5' check (BGW-only, auto-skipped on leaf nodes). Added to ALL_CHECKS, control_plane CHECK_SET, and docstring. 2. Add bgp_info = vxlan_obj.get_bgp_underlay_info_cached() in config_bgw_nodes and pass it to l3vni_sonic_bgw_dci and l3vni_frr_bgw_dci calls to fix BGP config lookup failures. Refactored L3VNI test cases to use new evpn_type5 check: - L3VNI_dci:1: checks=['vrf_vni', 'vlan_vni', 'evpn_type5'] - L3VNI_dci:2: checks=['vrf_vni', 'evpn_type5'] (Step 2) - L3VNI_dci:6: checks=['vrf_vni', 'evpn_type5'] (merged old Steps 2+4)

this is with DCI enabled. I am seeing these traffic items always enabled. |
Move DCI flap continuous stream creation from tgen_preconfig (upfront for all tests) to on-demand creation in test_dci_link_trigger via the new _create_dci_fc_streams() helper. This prevents UNAPPLIED traffic items in IXIA for tests that don't need DCI-FC streams. In tgen_preconfig: store endpoint data in stream_handles['_dci_fc_lazy'] instead of creating actual IXIA traffic items. In test_dci_link_trigger: call _create_dci_fc_streams() which creates the 4 stream variants (SH/MH x IPv4/IPv6) only when this test runs.
|
Addressed the "DCI traffic items always enabled" concern in commit fac2331 — DCI-FC continuous streams are now lazy/on-demand. What changed:
Result: Other tests running in the same DCI topology session no longer see UNAPPLIED traffic items for DCI-FC streams they don't use. |

Root cause: The bare topology_handle from create_topology_handles() is not registered in tg.py's self.topo_handle dict. When passed as device_handle to configure_ixia_bgp_ipv6/ipv4_session, tg_emulation_bgp_route_config's internal stop_all_protocols lookup fails with ValueError because it cannot find the topology in topo_handle.values(). Fix: Remove the device_handle parameter and always use tg_interface_config to create a fresh, properly registered topology+deviceGroup stack for the BGP session. This ensures the topology is tracked in tg.py's topo_handle dict, which is required for protocol stop/start operations. Applied to both IPv6 (L3VNI_dci:8) and IPv4 (L3VNI_dci:9) test cases.

…g_interface_config
Root cause: create_topology_handles() creates topologies via tg_topology_config()
but does NOT register them in tg.py's self.topo_handle dict. When
tg_interface_config(mode='config') is called later, it finds topo_handle[port]=None,
tries to create a NEW topology on the same port, and fails with Error 6502.
Fix: Both configure_ixia_bgp_ipv6_session() and configure_ixia_bgp_ipv4_session()
now accept an optional topology_handle parameter. When provided, the helper
registers it in tg_handle.topo_handle[port_handle] BEFORE calling
tg_interface_config. This causes tg_interface_config to see the existing
topology (not None) and reuse it instead of creating a new one, which:
1. Avoids Error 6502 (Port already used) - no duplicate topology creation
2. Avoids ValueError ('/topology:1' not in list) - topology is now registered
in topo_handle dict so stop_all_protocols lookup succeeds
Both test cases (L3VNI_dci:8 and L3VNI_dci:9) now pass topology_handle from
leaf_ports[port_key]['topology_handle'] to the helper functions.

@vallabh78 Fixed Error 6502 in commit 594785e. Root cause: Fix: Both This solves both issues:
Both test cases now pass |
Root cause: create_topology_handles() creates IXIA topologies on all ports during setup for L2VNI traffic. When L3VNI_dci:8/9 tests then call tg_interface_config on the same port, IXIA rejects with Error 6502 'Port already used' because each port can only have one topology. Fix: Following the bgp_ixia.txt pattern from reviewer, use tgapi.get_handle_byname() with a dedicated unused TGEN port that has no pre-existing topology. The test now: 1. Collects all ports already used by L2VNI topologies 2. Finds an unused TGEN port for the leaf node 3. Gets fresh (tg_handle, port_handle) via tgapi.get_handle_byname() 4. Passes clean port to helper - tg_interface_config creates fresh topology Also removes topology_handle parameter from configure_ixia_bgp_ipv6_session and configure_ixia_bgp_ipv4_session helpers (no longer needed since we use a clean port instead of trying to reuse existing topology).

i dont see any unused ports and testcase fails. lets use T1D5P3 for configuring bgp session to DUT. it has a topology already associated but no device groups created. Something like this (Pdb) pp leaf_topo_ports
|
…w topology Per reviewer feedback, all IXIA ports on leaf0_dc1 already have topologies from create_topology_handles() — there are no unused ports. Use T1D5P3 which has a topology but no device groups: test_vxlan_dci.py (L3VNI_dci:8 and L3VNI_dci:9): - Pick last non-PortChannel port from topo_handles (e.g. T1D5P3) - Extract tg_handle, port_handle, topology_handle from topo_handles dict - Pass topology_handle to helper functions vxlan_helper.py (configure_ixia_bgp_ipv6/ipv4_session): - Re-add topology_handle parameter - When topology_handle provided: create device group on existing topology via tg_topology_config(), then add ethernet + IPv4 stacks via tg_interface_config(protocol_handle=...) — same pattern as create_device_groups() - When topology_handle is None: fallback to original tg_interface_config with port_handle (creates fresh topology)
|
@vallabh78 Fixed Error 6502 "Port already used" in commit a7d2c8e by reusing the existing IXIA port topology instead of creating a new one. Implementation (per your guidance on T1D5P3):
Lab verification needed: Confirm T1D5P3 (or equivalent last single port) has a topology but no device groups, and that the device group creation pattern works correctly with IXIA API. |

… route config Root cause: create_topology_handles() creates IXIA topologies via tg_topology_config() directly, which does NOT register them in tg.py's internal topo_handle dict (port_handle -> topology_handle mapping). When tg_emulation_bgp_route_config() is later called, tg.py's trgen_adjust_mismatch_params() tries to look up the topology via list(self.topo_handle.values()).index(topo) and fails with ValueError because the bare topology was never registered. Fix: In both configure_ixia_bgp_ipv6_session() and configure_ixia_bgp_ipv4_session(), register the topology in tg_handle.topo_handle[port_handle] = topology_handle immediately after entering the topology_handle branch, before any subsequent IXIA API calls that trigger trgen_adjust_mismatch_params().

While configuring IXIA side BGP config, for ethernet we are not configuring vlan 99. |

1. Assign DUT physical interface as VLAN 99 member:
- configure_dut_ixia_l3_intf() now accepts dut_intf param and runs
'config vlan member add 99 <interface>' before VRF bind

- Both test cases resolve TGEN port name (T1D5P3) to DUT Ethernet
interface via vars lookup (D5T1P3 -> Ethernet224)
2. Verify BGP neighborship and routes from IXIA:
- New verify_dut_bgp_ixia_session() helper in vxlan_helper.py
- Checks BGP neighbor state is Established (show bgp vrf summary)
- Verifies expected prefixes in routing table (show bgp vrf ipv4/ipv6)
- Called in both L3VNI_dci:8 (IPv6) and L3VNI_dci:9 (IPv4) after
