SONiC Management API Wiki

There are many ways to communicate and interact with the PTF container and the DUT from the localhost. This wiki serves as a place to document these API calls. Below is a list of some of the many API calls.

localhost, ptfhost and sonichost objects can use the ansible modules. Many may not provide meaningful output if ptfhost is used (like reduce_and_add_sonic_images).

# These arguments are examples of the pre-configured function arguments

def test_fun(duthosts, rand_one_dut_hostname, ptfhost):
    duthost = duthosts[rand_one_dut_hostname]

    # example dut api call
    duthost.get_extended_minigraph_facts()
    
    # example ptf api call
    ptfhost.shell("ls")
