What type of bond to choose linux, if the links are connected to different switches in a stack?

You need to choose the fastest mode of bonding. Connecting to different switches for fault tolerance is necessary.

Solution
If your switches don't support MEC (Multichassis Etherchannel), something like a vss from Cisco or from a vpc Cisco nexus, it does. Only mode active/backup (ie both will not work).

PS it used to be right now, and most likely also, but maybe not.
I have cisco switches, vss no. Can you suggest why can not work at the same time say in balance-rr? - Serena_Deckow commented on March 12th 20 at 08:03
If 2 or more ports connected to the same switchboard (or to the stack or to the several igniters using technologies I mentioned above) and combined group (Bonding/etherchannel), these ports are considered as one logical port. If from one device to connect 2 or more ports in different igniters, they are considered as separate ports. In this case, if you are running STP, it will block all but one, so you get the Active/Backup. STP if not, then get the loop and loop will get stable table Mac address + Broadcast storm .When the storm igniters bent. - kelli_Wolf commented on March 12th 20 at 08:06
