Hi all,


Hi can anyone explain me why in in DTS 18.02, dut_prerequisites(), it is calling disable_tester_ipv6().
Why is there a need of disabling testers IPV6 support.

While executing testcases it is showing me this:  DUT PORT MAP: [-1, -1], and there is a Index Error exception raised.

File "/root/dts-18.02/framework/dut.py", line 984, in disable_tester_ipv6
    if self.tester.ports_info[tester_port]['type'] != 'ixia':
IndexError: list index out of range


However if I comment out the disable_tester_ipv6() function call, I am able to run some test cases, while some test cases  fail and raise ParameterInvalidException,

File "/root/dts-18.02/framework/tester.py", line 188, in get_interface
    raise ParameterInvalidException("local port should not be -1")
ParameterInvalidException: local port should not be -1
