Moving component to rhel-osp-director--This param is blocked at the "openstack overcloud deploy" script level.

The need for the Cisco Nexus ML2 mechanism driver's ability to utilize N9K VXLAN endpoint support for openstack neutron VLAN network segments.

Comment 3 Brad P. Crochet 2015-10-20 13:18:17 EDT
There is nothing in the client that is preventing this.

What error do you see? Have you tried '--neutron-tunnel-types nexus_vxlan --neutron-network-type nexus_vxlan'?
Comment 4 Brad P. Crochet 2015-10-20 14:40:44 EDT
You will also need to create an environment file that specifies:

    NeutronTypeDrivers: vxlan,vlan,flat,gre,nexus_vxlan

and then pass that file with a -e

Thanks, Brad... I added my comment based on a meeting discussion with Eugene (the original bug creator).  I think the specifics were misunderstood by me there so I'll get with him and get clarification and help him retest it.

My understanding the things we need to set:
   NeutronTypeDrivers: 'nexus_vxlan,vxlan'
   --neutron-network-type nexus_vxlan OR NeutronNetworkType: 'nexus_vxlan'
   --neutron-tunnel-type nexus_vxlan

I just ran redeploy like this and heiradata seems ok but some failures on neutron restart: 

  in openstack overcloud deploy
    --neutron-network-type nexus_vxlan
    NeutronMechanismDrivers: 'openvswitch,cisco_nexus,cisco_ucsm'

    NeutronTypeDrivers:  'nexus_vxlan,vlan'

So, I think this BZ is either not valid or would apply to something in heat or puppet.
Comment 6 Evgeny 2015-11-06 09:44:14 EST
it's not valid. I agree now
