Hi Forum,
I am trying to configure openvswitch to use LACP on a bonded interface on
Ubuntu 14.04 with VLANs using Cisco 3850X switches.
I want bond NICs eth2, eth3, eth4 and eth5 together. On the server I will
have VMs on to VLANs 500 and VLANs 590.
On the Cisco 3850X Switch I have configures ether channel and enabled LACP.
interface Port-channel20
switchport trunk native vlan 500
switchport trunk allowed vlan 400-599
switchport mode trunk
interface GigabitEthernet1/0/11
description eth2
switchport trunk native vlan 500
switchport trunk allowed vlan 400-599
switchport mode trunk
channel-protocol lacp
channel-group 20 mode active
!
interface GigabitEthernet1/0/12
description eth3
switchport trunk native vlan 500
switchport trunk allowed vlan 400-599
switchport mode trunk
channel-protocol lacp
channel-group 20 mode active
interface GigabitEthernet2/0/11
description stage eth3
switchport trunk native vlan 500
switchport trunk allowed vlan 400-599
switchport mode trunk
channel-protocol lacp
channel-group 20 mode active
!
interface GigabitEthernet2/0/12
description eth4
switchport trunk native vlan 500
switchport trunk allowed vlan 400-599
switchport mode trunk
channel-protocol lacp
channel-group 20 mode active
LACP can see the server from the switch. (MAC shown matches MAC of vmbr0)
#show lacp neighbor
Flags: S - Device is requesting Slow LACPDUs
F - Device is requesting Fast LACPDUs
A - Device is in Active mode P - Device is in Passive mode
Channel group 20 neighbors

On the HP server I have the default Ubuntu 14.04 server OVS package
installed.
sudo dpkg -l | grep openvswitch
ii openvswitch-common 2.0.2-0ubuntu0.14.04.1
amd64 Open vSwitch common components
ii openvswitch-switch 2.0.2-0ubuntu0.14.04.1

I have configured the /etc/network/interfaces to have
#cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# Bond eth2, eth3, eth4, eth5 together

After reboot with above configuration
#sudo ovs-vsctl show

The NICs have the following hardware addresses (Note the virbr0 - should
that be there?)
#ifconfig | grep -i HWAddr

sudo ovs-appctl bond/show bond0
[sudo] password for builder:

I have disabled the firewall on the server.
But I am unable to ping the VLAN 500 or VLAN 590 IPs
Could someone point me towards what I have setup wrong?
Thanks
Stuart
