[openstack-dev] [ironic][neutron] bonding?

Hi Jim,

Neutron is supporting resource tagging [1] which is support currently  network resource_type
With a simple change is neutron you can also allow resource tagging for port resource_type [2]

This will allow you to tags ports and indicate that they are in the same group
maybe that can work better the ironic port group concept.

There's rumors floating around about Neutron having a bonding model in
the near future. Are there any solid plans for that?

Who spreads these rumors :)?

To the best of my knowledge I have not seen any RFE proposed recently along these lines.

For context, as part of the multitenant networking work, ironic has a
portgroup concept proposed, where operators can configure bonding for
NICs in a baremetal machine. There are ML2 drivers that support this
model and will configure a bond.

Some folks have concerns about landing this code if Neutron is going to
support bonding as a first-class citizen. So before we delay any
further, I'd like to find out if there's any truth to this, and what the
timeline for that might look like.
