I have 2 SG500XG-8F8T switches and 3 SG500 switches. each set up in there own stack Currently SG500 running at 5G and SG500xg running at 10G between them.. with a 1G connection connecting the 2 stacks. Is there a way to get all 5 switches in the same stack running at 5G? Or would I have to create a LAG to get the additional bandwidth between stacks.
