Control Node Network Configuration

Control Plane Network configuration:

The Control Plane is virtualized on Rhev.  The network breaks down like so:

On the Switch:

A single LACP port channel with the native vlan configured to be the internal_api network the control node is in.  For example it would be this if the control node were in CCB

switchport trunk native vlan 2380

Along with the following allowed vlans:

switchport trunk allowed vlans 2317,2380-2381,91,1457,90,438,422

This will include:

  • The external and vip-net networks
  • The internal_api and tenant networks
  • Any external subnets used

Rhev:

The VM is hosted on Rhev so a single network interface attached to the network not tagged.

OS:

OVS or Openvswitch is used to configure the interfaces in the operating system.  It looks like this:

Two Bridge Compute Node Network Configuration

The compute host is connected to two switches. The Vapor switch and the provider switch.

Vapor Switch:

A single LACP portchannel is configured and connected to the host. The following native vlan is configured and should be the internal_api subnet configured for that data center. For example this is the config needed for a compute host in CCB:

switchport trunk native vlan 2380

Along with the following allowed vlans:

switchport trunk allowed vlans 2380-2381

This will include:
The internal_api and tenant networks

OS:
An LACP Bond is configured on the host: Bond0
OVS or Openvswitch is used to configure the interfaces in the operating system. It looks like this:

Provider Switch:

Native Vlan does not need to be configured on the provider switch. However if there is one it cannot include an allowed vlan.

switchport trunk native vlan 94

Along with the following allowed vlans:

switchport trunk allowed vlans 91,1457,90,438,422

This will include:
Any external subnets used as provider networks in openstack

The OS configuration includes a bonded interface named bond1
OVS or Openvswitch is used to configure the interfaces in the operating system. It looks like this:
