Help with Cisco LAG

[tripalreno4]

When applying a LAG between two Cisco switches and also between another vender router and switches, I understand that certain settings must match, for example with LACP one or both sides must be set to active, trunk settings, duplex and speed must match as well as allowed VLANs. However, in regards to applying load balancing algorithms, which options vary between even different models of Cisco equipment as well as other venders, do both sides of the LAG need to be using the same algorithm for load balancing or can they be different. For example, on one side src-dst-ip on other side src-dst-mac?

Great question. Possibly not related to DNAC at all because the appliance does not support LAG as far as I know ... or does it?

But your question applies generally. I would say the load balancing algorithm determines which link is used for packet forwarding, and not for reception. Once the packet is on the link towards its destination, then the destination will receive it and process it. Therefore you can mismatch them at either end and the receiver won't need to match the sender's mode of operation. Mismatching may not have the desired effect on the link utilisation that you are perhaps expecting/hoping though.
