I Have 2 SG310s in HA, and 2 Cisco SX350X switches connected with 2 DAC cables in a LAG. There is a 4 node Nutanix Block. Coming out of each node in the block are 2 DAC cables going to each SX350X switch for redundancy. I am trying to connect these 2 switches to my SG310s with redundant links and use the SG310 as my Gateway to the rest of the Active Interfaces/Network. Spanning tree is disabled on the switches due to causing issues with the Nutanix Block, so I am using LACP and Protected Ports instead. I was thinking of doing an Aggregation Group on the UTM, so 4 connections in total with the HA, but wasn't sure if that would work coming from 2 different switches. The link below is a diagram of what I envision to make this easier to follow. If a switch goes down the idea is for the other switch to take over and the UTM Interface to use the interface that is still up.
What is the best way to accomplish this. LAG ? Multipath Rule?
Any help is appreciated.
