Thx for all!
 
Now we are testing this basic configuration (it can be helpfull for somebody):

Hi Alex,

I'm using a similar setup on c3560-X (configuration should be the same).

on the switch:

interface Port-channel1
  description srv, RHEV-01, lacp, trunk
  switchport trunk encapsulation dot1q
  switchport trunk native vlan 666
  switchport mode trunk


and on all ports leading to the server

interface GigabitEthernet0/10
  description srv, rhev01, eth1
  switchport trunk encapsulation dot1q
  switchport trunk native vlan 666
  switchport mode trunk
  channel-protocol lacp
  channel-group 1 mode active
!
...


you can also use "port-channel load-balance src-dst-ip" on cisco side
and set "xmit_hash_policy=layer2+3" on linux side to calculate XOR by
MAC and IP addresses (default is to XOR only MAC addresses).

 
oVirt generate ifcfg-* config files automaticaly. Can I edit it? I think by default it uses "layer3+4"
 
 
 




Cheers, Dron

 Hi, community!

 I have made bond0 mode4 (eth0+eth1+eth2+eth3) by oVirt portal. It's work
 well on CentOS 7 node.

 How I can setup my cisco 2960 XR switch for work with this bond0 for
 loadbalancing + aggregation (802.3ad)?
