commit b935f9d9a7c7bc872b49d66ce6ee586283ce69c0 Author: Nate Johnston <[email protected]> Date: Mon Jul 16 11:26:20 2018 -0400 Add list of all working DSCP marks There is no place in the documentation that explicitly lists the valid DSCP marks, except for an incomplete hint in the DSCP spec in neutron-specs. This provides an explicit list. Change-Id: Ic350c88e59c33d98b54086707c9add05cf137dc2 Closes-Bug: #1781915 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1781915 Title: QoS (DSCP Mark IDs) – No correlation between the implemented functionality and design Status in neutron: Fix Released Bug description: ### General Description ### There is a “Proposed Change” regarding “QoS DSCP marking support” as it documented in: http://specs.openstack.org/openstack/neutron-specs/specs/newton/ml2-qos-with-dscp.html We propose an update to the QoS API and OVS driver to support DSCP marks. Valid DSCP mark values can be between 0 and 56, except 2-6, 42, 44, and 50-54. ### Test scenario ### 1) ssh to your Undercloud host 2) switch to “stack” user with: “su – stack“ 3) Source overcloudrc file with: “source overcloudrc” 4) Upload the attached “Check_DSCP_Options.py” Python script (inside the attached *.zip) to your home directory (stack home) and run it with “python Check_DSCP_Options.py” command while monitoring “server.log” on your controller node. ### Expected Result ### Valid DSCP mark values can be between 0 and 56, except 2-6, 42, 44, and 50-54. ### Actual Result ### 1) Failed DSCP mark IDs: [1, 2, 3, 4, 5, 6, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 42, 43, 44, 45, 47, 49, 50, 51, 52, 53, 54, 55] 2) As you can see we do have supported and not DSCP Mark IDs, but it has different behavior than expected. 3) You can find the controller “server.log” attached (inside attached *.zip) and you can see there messages like this one: 2018-07-02 15:04:58.535 28 INFO neutron.api.v2.resource [req- 74bb7060-b9b2-4542-bd8a-d805a8ff079c b4332e1592ab480f96fc87e5af797895 f3f03848a45746c7bcbe95b625d7e1d8 - default default] update failed (client error): Invalid input for dscp_mark.
