…nter and global_pause test-script (sonic-net#22490) Description of PR Added support for tgen_port_info in: tests/snappi_tests/pfc/test_global_pause_with_snappi.py tests/snappi_tests/pfc/test_tx_drop_counter_with_snappi.py Summary: Fixes # (issue) Type of change Bug fix Testbed and Framework(new/improvement) New Test case Skipped for non-supported platforms Test case improvement Back port request 202205 202305 202311 202405 202411 202505 202511 Approach What is the motivation for this PR? The tgen_port_info was added as part of Snappi test infra improvement, which enabled users to select between static (from variables.override.yml) and dynamic (select 100 and 400Gbps ports) ports. This was NOT included in test_tx_drop_counter and test_global_pause test-scripts under snappi_tests/pfc section. How did you do it? Imported the tgen_port_info from snappi_fixtures.py and removed any reference to old setup_dut_port function for both test-scripts. How did you verify/test it?

…ion (sonic-net#22504) Description of PR The tgen_port_info infra function in common/snappi_tests/snappi_fixtures.py is used to select port (dynamically or statically) for the test. During static port selection, the variables.override.yml file is used to select Rx and Tx port for the test. However, after the test, there was no explicit test clean_up code. This PR addresses it. Summary: Fixes sonic-net#20993 Type of change Bug fix Testbed and Framework(new/improvement) New Test case Skipped for non-supported platforms Test case improvement Back port request 202205 202305 202311 202405 202411 202505 202511 Approach What is the motivation for this PR? The tgen_port_info is used to select the Rx and Tx port for the test. In case of static port selection, the function returned snappi_dut_base_config(duthosts, snappi_ports, snappi_api, setup=True), and there was no explicit cleanup after the test. How did you do it? If the 'is_override' flag is true, the static port selection code is used to select Rx and Tx ports from variables.override.yml file. Instead of returning with function 'snappi_dut_base_config', 'yield' is called to ensure that clean-up is called at the end of the test. Once yield returns back to the test, then 'setup_dut_ports' is called with setup=False to ensure that clean-up happens after the test. How did you verify/test it? For verification of this changes on 202511 branch, please refer to PR sonic-net#22441 Verification of the PR on master with multi-dut setup: azureuser@7e081020c2c7:/data/tests$ date;python3 -m pytest

…kets not received on collector interface (sonic-net#22186) * [sonic-mgmt] Fix sflow/test_sflow.py failures with expected sflow packets not received on collector interface Issue #1: In some cases (like sflow config enabled for first time, device reboot), hsflowd daemon is taking little over 3 mins to be fully initialized and process collector config. During this window, hsflowd service won't send sflow packets ('CounterSample', 'FlowSample' etc) to collector interface and thus test can fail with i) "Packets are not received in active collector, collector\d+" and ii) "Expected Number of samples are not collected from Interface Ethernet\d+ in collector collector\d+ , Received \d+" hsflowd service is writing to "/etc/hsflowd.auto" once it's processed collector configuration. Thus waiting for collector info to be present in "/etc/hsflowd.auto" seems to be safe option before proceeding with sflow traffic verfication. Issue #2: If the test expects flow samples/packets on the collector interface but they aren't seen for some reason, then we are hitting "KeyError: 'flow_port_count'". Due to counter samples seen on collector interface, "data['total_samples']" will not be zero but "data['total_flow_count']" will be 0 and lead to KeyError when tried to access "data['flow_port_count']". Fix is to have assert on "total_flow_count" and "total_counter_count" before calling corresponding sample analyze functions. Signed-off-by: Vinod <vkjammala@arista.com> * Addressing review comments 1) Enhanced "wait_until_hsflowd_ready" to make it wait for all the collector IPs (instead of calling it sequentially for each IP) 2) Add docstring for "wait_until_hsflowd_ready" function 3) Updated "ast.literal_eval" usage to handle the case where "active_collectors" is passed as empty string ("" instead of "[]") Signed-off-by: Vinod <vkjammala@arista.com> * Fix pre-commit check failures Signed-off-by: Vinod <vkjammala@arista.com> * Revert PR#21674 partially to enable "sflow/test_sflow.py" test Signed-off-by: Vinod <vkjammala@arista.com> --------- Signed-off-by: Vinod <vkjammala@arista.com>

…ion (sonic-net#22504) Description of PR The tgen_port_info infra function in common/snappi_tests/snappi_fixtures.py is used to select port (dynamically or statically) for the test. During static port selection, the variables.override.yml file is used to select Rx and Tx port for the test. However, after the test, there was no explicit test clean_up code. This PR addresses it. Summary: Fixes sonic-net#20993 Type of change Bug fix Testbed and Framework(new/improvement) New Test case Skipped for non-supported platforms Test case improvement Back port request 202205 202305 202311 202405 202411 202505 202511 Approach What is the motivation for this PR? The tgen_port_info is used to select the Rx and Tx port for the test. In case of static port selection, the function returned snappi_dut_base_config(duthosts, snappi_ports, snappi_api, setup=True), and there was no explicit cleanup after the test. How did you do it? If the 'is_override' flag is true, the static port selection code is used to select Rx and Tx ports from variables.override.yml file. Instead of returning with function 'snappi_dut_base_config', 'yield' is called to ensure that clean-up is called at the end of the test. Once yield returns back to the test, then 'setup_dut_ports' is called with setup=False to ensure that clean-up happens after the test. How did you verify/test it? For verification of this changes on 202511 branch, please refer to PR sonic-net#22441 Verification of the PR on master with multi-dut setup: azureuser@7e081020c2c7:/data/tests$ date;python3 -m pytest

…kets not received on collector interface (sonic-net#22186) * [sonic-mgmt] Fix sflow/test_sflow.py failures with expected sflow packets not received on collector interface Issue #1: In some cases (like sflow config enabled for first time, device reboot), hsflowd daemon is taking little over 3 mins to be fully initialized and process collector config. During this window, hsflowd service won't send sflow packets ('CounterSample', 'FlowSample' etc) to collector interface and thus test can fail with i) "Packets are not received in active collector, collector\d+" and ii) "Expected Number of samples are not collected from Interface Ethernet\d+ in collector collector\d+ , Received \d+" hsflowd service is writing to "/etc/hsflowd.auto" once it's processed collector configuration. Thus waiting for collector info to be present in "/etc/hsflowd.auto" seems to be safe option before proceeding with sflow traffic verfication. Issue #2: If the test expects flow samples/packets on the collector interface but they aren't seen for some reason, then we are hitting "KeyError: 'flow_port_count'". Due to counter samples seen on collector interface, "data['total_samples']" will not be zero but "data['total_flow_count']" will be 0 and lead to KeyError when tried to access "data['flow_port_count']". Fix is to have assert on "total_flow_count" and "total_counter_count" before calling corresponding sample analyze functions. Signed-off-by: Vinod <vkjammala@arista.com> * Addressing review comments 1) Enhanced "wait_until_hsflowd_ready" to make it wait for all the collector IPs (instead of calling it sequentially for each IP) 2) Add docstring for "wait_until_hsflowd_ready" function 3) Updated "ast.literal_eval" usage to handle the case where "active_collectors" is passed as empty string ("" instead of "[]") Signed-off-by: Vinod <vkjammala@arista.com> * Fix pre-commit check failures Signed-off-by: Vinod <vkjammala@arista.com> * Revert PR#21674 partially to enable "sflow/test_sflow.py" test Signed-off-by: Vinod <vkjammala@arista.com> --------- Signed-off-by: Vinod <vkjammala@arista.com>
