Description Eran Kuris 2017-06-29 06:00:12 UTC

Description of problem:
In OSP there is an option to set different MTU value for each physnet.
We need to have an option to set it as a part of OSPD and add this parameter to heat template. 

Version-Release number of selected component (if applicable):
rpm -qa |grep triple
openstack-tripleo-puppet-elements-6.0.0-3.el7ost.noarch
python-tripleoclient-6.1.0-6.el7ost.noarch
openstack-tripleo-image-elements-6.0.0-2.el7ost.noarch
puppet-tripleo-6.3.0-12.el7ost.noarch
openstack-tripleo-ui-3.1.0-9.el7ost.noarch
openstack-tripleo-validations-5.5.0-1.el7ost.noarch
openstack-tripleo-common-6.0.0-8.el7ost.noarch
openstack-tripleo-heat-templates-6.0.0-12.el7ost.noarch

How reproducible:
always

Steps to Reproduce:
1. grep -ir mtu /usr/share/openstack-tripleo-heat-templates/

2.
3.

Actual results:
no option to set physical_network_mtus via director

Expected results:
an available parameter of physical_network_mtus

Comment 1 Assaf Muller 2017-07-17 18:24:58 UTC

Is that option something we want to support in TripleO?

Comment 2 Ihar Hrachyshka 2017-07-26 21:24:34 UTC

Yes, that's something we should support. I think Brent is a better person to give the timeline on that one. We discussed it a bunch of times in the past that we need it exposed.

Comment 5 Matt Flusche 2018-03-09 16:23:40 UTC

At the moment this can be set with hiera data in ExtraConfig, example:

parameter_defaults:
  ExtraConfig:
    neutron::plugins::ml2::physical_network_mtus: ["external:1500"]

Comment 7 Kamil Sambor 2018-09-24 08:41:14 UTC

Because there is easy workaround, this task is more clean-up than a bug. So there is no reason to backport this changes (changes was released in stable Rocky)
