Looking for some help setting up a warm spare between a MS350 and a MS320. I have them connected together through a LAG on the SFP+ ports Both have L3 Routing enabled. My issue is that when I click on the warm spare I am presented with a 'No Warm Candidates' available. Both of these switches are connected to my Sophos UTM in port 1 and port 5.   I cannot stack these two since the MS320 does not having the stacking ports. I'm thinking that it may have to with me creating some L3 interfaces, but not quite sure. I looked through the guide and it wasn't much help.   Any help would be greatly apprecaited.   Thank you ...
