Hello,

I try to run lag_2 test in t1-64-lag topology, but it always hangup at lag_run_ptf.yml:10:

TASK [test : Run lag_test.LacpTimingTest on PTF docker.] ***********************
task path: /var/polly_hsu/sonic-mgmt/ansible/roles/test/tasks/lag_run_ptf.yml:10

I check lag_2.yml, it has included testbed topology configuration for t1-lag, t0, and t0-116.
Is it the reason for the hangup in t1-64-lag? (No problem when running lag_2 in t0 or t1-lag)

• name: Include testbed topology configuration (to get LAG IP and PTF docker interfaces, that are behind LAG VMs).
  include_vars: vars/topo_t1-lag.yml
  when: testbed_type == 't1-lag'

• name: Include testbed topology configuration (to get LAG IP and PTF docker interfaces, that are behind LAG VMs).
  include_vars: vars/topo_t0.yml
  when: testbed_type == 't0'

• name: Include testbed topology configuration (to get LAG IP and PTF docker interfaces, that are behind LAG VMs).
  include_vars: vars/topo_t0-116.yml
  when: testbed_type == 't0-116'

Please advise.
Thanks a lot!
