It might be worth explaining here more of what specifically is being checked by the PMD. It seems like there is different expected output based on whether promisc mode is on or not as well as different behaviors with different MAC addresses. . > + > +If packets should be received and forwarded, or received and not forwarded, > +depending on the configuration, the port info should match the expected > behavior. > +""" <snip> > + def test_default_mode(self) -> None: > + """Tests default configuration. > + > + Creates a testpmd shell, verifies that promiscuous mode is enabled > by default, > + and sends two packets; one matching source MAC address and one > unknown. > + Verifies that both are received. > + """ > + testpmd = TestPmdShell(node=self.sut_node) > + isPromisc = testpmd.show_port_info(0).is_promiscuous_mode_enabled > + self.verify(isPromisc, "Promiscuous mode was not enabled by > default.") > + testpmd.start() > + mac = testpmd.show_port_info(0).mac_address > + # send a packet with Rx port mac address > + self.send_packet_and_verify(should_receive=True, > mac_address=str(mac)) > + # send a packet with mismatched mac address > + self.send_packet_and_verify(should_receive=True, > mac_address="00:00:00:00:00:00") We should be careful using the MAC address that is all 0s as that is a special address that is reserved for localhost. I think it would still work in this case since it wouldn't match the address of the tester's port anyway, but it might be safer to just make the last digit of this a 1 regardless. > + testpmd.close() > + sleep(6) > + <snip> > 2.44.0 >
