We have two MS425-32 switches that are stacked, We also have two SD-WAN devices (not Meraki) that are configured for HA. It has never worked, I am hoping someone has got this configured and working and can share the correct config with me. Firstly I should mention the SD-WAN devices do not like LACP they have bridged ports. 2 ports per device are configured. I have set the ports on the MS devices on the same VLAN (2) on trunk ports with RSTP disabled and STP loop guard enabled. Ports number 1 on the two switches are set to be connected to the primary SD-WAN device and ports number 2 to the secondary SD-WAN device. Currently, only one port is connected to the SD-WAN device, when I connect the other port on the other switch the internet goes down. How can I achieve two active uplink ports and two standby uplink ports? Is there anyone out there with a similar setup that can help me?
