OVS Kernel - VF LAG Configuration

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

   Copy

   Copied!

               
   
               
   - 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:

   Copy

   Copied!

               
   
               
   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
