Port 49 & 50 just need to be set to TRUNK. Then they will carry both tagged
and untagged packets across the fibre link between the 2 switches.


The link to the 200/300 switches does not even match the screens I have on

You probably have an older firmware and the GUI has changed.

This is what I thought too. But looking at config samples from here,
https://www.cisco.com/c/en/us/support/switches/sg200-50p-50-port-gigabit-poe-smart-switch/model.html#ConfigurationExamplesandTechNotes
 ,
if a port is set to TRUNK it'll carry tagged & untagged packets.

"Trunk — Designed to connect 2 switches. Carries both untagged packets
and tagged packets."

Incorrect. P49 is the ROOT and P50 is the ALTERNATE. There can only be 1
root within a Spanning Tree. If the link on P40 goes down, P50 will become
the new root and Spanning Tree will reconfigure itself on all the switches.

I thought I saw this before but I thought they were "greyed out" and not
the active config. A good example of why I much prefer CLI over GUI for
configuring network equip.

All non-trunk ports, other than P49, P50, set to GENERAL for now just to
see if we can get basic communication between the 2 switches on VLAN 20.

I'd really like to see the actual config file if you're able to export it
out.

This is about as simple of a switch & vlan config there is. This shouldn't
be such a project.
