OVS Kernel - VF LAG Configuration

1. Make sure that the compute.yaml file has a Linux bond: 

   - type: linux_bond
     addresses:
       - ip_netmask:
           get_param: TenantIpSubnet
     name: bond0
     bonding_options:
       get_param: BondInterfaceOvsOptions
     members:
       - type: sriov_pf
         name: enp3s0f0
         link_mode: switchdev
         numvfs: 64
         promisc: true
         use_dhcp: false
       - type: sriov_pf
         name: enp3s0f1
         link_mode: switchdev
         numvfs: 64
         promisc: true
         use_dhcp: false

2. Make sure the /usr/share/openstack-tripleo-heat-templates/environments/ovs-hw-offload.yaml file has hw-offloading enabled:
   

   ComputeSriovParameters:
     OvsHwOffload: True

3. Configure the bonding option in the same file:
   

   parameter_defaults:
      BondInterfaceOvsOptions: "mode=active-backup miimon=100"

   The supported bonding modes for vf-lag are:

• Active-Backup
• Active-Active
• LACP

Following is an example of an uplink over a VLAN number 77 in a bond use:

- type: interface
  name: bond0.77
  use_dhcp: false
  addresses:
  - ip_netmask:
      get_param: TenantIpSubnet

Following is an example of an uplink of a general interface:

- type: interface
  name: enp2s0f1.7
  use_dhcp: false
  addresses:
  - ip_netmask:
      get_param: TenantIpSubnet
