Approach

What is the motivation for this PR?

The platform_tests/api/test_chassis.py::test_status_led testcase code logic assumes that the chassis main led is always controllable.

But for some of the Cisco devices this test logic:

status_led = duthost.facts.get("chassis").get("status_led")

always returns None, which means that the chassis led is not controllable. That is why I introduce such change - to assume on default that the chassis led is not controllable.

How did you do it?

Change the led_controllable = False variable value.

How did you verify/test it?

Run the platform_tests/api/test_chassis.py.

Any platform specific information?

Supported testbed topology if it's a new test case?
