I agree with @_Val_ . So, the gist of it exactly what he said...you configure them in Gaia first (OS level) and once done, then you fetch topology.
BUT, here is the catch...if interface is DOWN state, it will never be fetched by topology, regardless if you click "get interfaces with topology" or "get interfaces without topology".
So, for it to show in dashboard, state has to be UP.
In your case, you would run this from clish -> set interface eth1-01 state up and then save config on next line
Hope that helps.
