Hi I am looking at purchasing x2 Cisco SG550XG-24F switches (in a stack). I currently have 2 of them in 10Gb BASE-T and functionality wise work great for us. I am trying to wrap my head SFP+ and the question I have is: Will Twinax Cable (SFP-H10Gb-CU1M) work for SG550XG-24F switch connectivity (no separate transceivers)? I have read this guide which only states Twinax is compatible for stacking ports: “The Cisco SFP+ Copper Cable modules for stacking that are supported in the Cisco 550X Series Stackable Managed Switches are: SFPH10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M.” But looking at the Cisco SG500X Switch Accessories document: The same cable appears to be compatible for stacking AND connectivity. Am I right in thinking that a Cisco SFP Twinax Cable (Passive) should work in a Cisco SG550XG-24F SFP+ switch port no problem? Is anyone else using this switch with Twinax? Thanks 😊!

I have a couple question regarding the Cisco SG300x switches and stacking. I am new to Cisco in general so doing plenty of planning. I want to stack 2 SG300x switches and have full redundancy in case of failure:
Because there are only 2 switches, Will this mean there will be a Master and the second switch will be a backup (and not slave)?
Reading the master selection process for these switches it looks like it differs slightly from the Catalyst switches. There does not appear to be a stack member priority setting. So I am thinking of Forcing the Master. Then also setting the Unit ID for both switches (master unit being lower). Will this work and is it recommended in my scenario? Or is there in fact a priority setting I am missing?
For the foreseeable future, there will only likely be 2 switches. In terms of stack connectivity/topology, I plan to link switch1 XG3/S1 to switch2 XG3/S1 and link switch1 XG4/S2 to switch2 XG4/S2. Will the stack use the S1 connection and have S2 as a backup in case of cable/port failure? If I expand the stack later on, I can switch to a proper ring topology?
In terms of setting up the stack, I saw this demo. If I power them on in the correct order and then force the master, Is that all I really need to do to get a native stack up and running?
Can these switches do a cross stack etherchannels? I plan to connect vSphere hosts (Active/Active connections on separate host NICs) for redundancy.
What should I be doing with STP in a stack?
