Yes, I do mean other Meraki devices, primarily switches.
How are you connecting your switches? Are they stacked or are you trunking the ports? I don't know that stacked switches really applies to what I'm asking here, more or less when you're looking at the "switch ports" and the digital view shows you which ports are live, using PoE, uplink, etc...that perhaps they could have an identifier for the downlink to the next switch? I also think RTSP should list the port connections between each device, but that's a whole different discussion.
