I know that you can use bonding mode 4 with 1 servers with 2 nic using 2 switch.
Bond 0 made of : Nic 1 port 1 -> switch A Nic 2 port 1 -> switch B
In this case I can loose a switch or a nic or a cable and still have my network working, if everything is working I will have link aggregation on the top of high availability .
My question is can you do the same but with 4 NIC to have more speed and still play it safe.

The switch will probably be CISCO.
