Hi all, From my understanding, the promiscuous mode feature will verify the functionality of promiscuous mode when it is on or off. The plan for testing this feature is as follows: Sending over a packet to verify the ports are working properly before any testing. First to verify the promiscuous mode is enabled. With the promiscuous being enabled, send over a packet and check if the packet will be received when sending it to a different destination mac address than the host/card. Then disable the promiscuous mode. The packet will only be received if the mac address is the destination mac address. Otherwise, the test case will be considered a failure. Please let me know if there is anything I need to add on or if there are certain cases I need to be aware of. Thanks, David Liu UNH Interoperability Lab

Small bit of context here, the described case already exists in the DTS Dynamic Config tests. So, would the other corner cases and "modes" justify additional test case development, etc. On Wed, Jun 24, 2020 at 4:03 PM Thomas Monjalon <thomas@monjalon.net> wrote: > Hi, > > A bit of context: David is going to implement a test in DTS > for promiscuous mode: > http://doc.dpdk.org/guides/nics/features.html#promiscuous-mode > > 24/06/2020 18:18, David Liu: > > Hi all, > > > > From my understanding, the promiscuous mode feature will verify the > > functionality of promiscuous mode when it is on or off. > > You need to check in which condition the promiscuous mode can be enabled. > Some contexts may forbid this mode. untrusted VF? flow isolation mode? > > > The plan for testing this feature is as follows: > > > > Sending over a packet to verify the ports are working properly before any > > testing.
