at some version It deletes existing ports & the associated data immediately when you modified the list. I'm not going to try that again because it immediately delets all the history.
What is it with solarwinds and deleting data from the database?
on Juniper switches the bridge data is associated with the virtual (unit) interfaces (type53), whereas on other manufacturers switches they are associated with the physical port (type 6)
So this isn't a viable solution in a mixed environment.
