AN is not gettign disabled to the last ports in a loop

[selldinesh]

Tried the below snippet

import pytest import snappi from tests.common.fixtures.conn_graph_facts import conn_graph_facts,fanout_graph_facts from tests.common.ixia.common_helpers import get_vlan_subnet, get_addrs_in_subnet,get_peer_ixia_chassis from tests.common.ixia.ixia_helpers import IxiaFanoutManager, get_tgen_location from tests.common.ixia.ixia_fixtures import tgen_ports,snappi_api from tests.common.helpers.assertions import pytest_assert from tests.common.utilities import wait_until logger = logging.getLogger(name) PORT_COUNT=6 MPATH=PORT_COUNT-1

@pytest.fixture(scope='module')

def test_bgp_convergence_config(snappi_api,tgen_ports): """ 1.Configure IPv4 EBGP sessions between the test ports 2.Advertise IPv4 routes 3.Configure and advertise same IPv4 routes 4.Configure another IPv4 session to send the traffic. """

config = snappi_api.config()
for i in range(1,PORT_COUNT+1):
    config.ports.port(name='Test Port %d'%i,location=tgen_ports[i-1]['location'])
    config.devices.device(name='Topology %d'%i,container_name=config.ports[i-1].name,device_count=1)

config.options.port_options.location_preemption = True

def confLayer1():
    for i in range(1,PORT_COUNT+1):
        layer1 = config.layer1.layer1()[-1]
        layer1.name = '%s port settings'%config.ports[i-1].name
        layer1.port_names = [config.ports[i-1].name]
        layer1.ieee_media_defaults = False
        layer1.auto_negotiation.rs_fec = False
        layer1.auto_negotiation.link_training = False
        layer1.speed= "speed_100_gbps"
        layer1.auto_negotiate = False

confLayer1()
snappi_api.set_config(config)
return config

After running this the last ports AN is not still disabled for the rest of the ports AN is off If I run the script once again then AN is turned off for the last port and link comes up

@selldinesh : Hi Dinesh, not able to reproduce this issue with my Novus 100G setup. Can you replace the tgen_ports with your ports and try to run this script. The validation part is added as well, would be easy to find out where it is failing

Hi Anish,

Sure, Will run it by tmrw and let you know the status.

Thanks, Dinesh
