Bonding on different switch

[zainal]

Hi,

i have server that running openstack (kvm). For public, we have bonding nic (nic1,nic2). We plan to do redundancy for this bonding. The bonding using active-backup (active/passive) mode. 

Nic1 will be active and nic2 is backup. Both nic connected to different switch. From what i found on the net, bonding active-backup normally using same switch but on different port channel. Is it possible to develop my plan? Advice needed.

Thanks.

Hi,

When bounding 2 different NICs from a server to a switch (or 2 if the switches are stacked or vss) The NICs need to be in the same Portchannel.
