BPDU block on edge and mac-limit

it would be a great addition making it possible to block/shutdown edge switchports if a spanning-tree BPDU is seen or number of mac addresses raises over a certain level.

The background for this request is to limit users from installing third party switches which can break your topology.

Bonus would be to do spanning-tree root guard as well.

Overall that would raise the enterprise capability of the products quite significantly.

    Hi @jonashauge ,

    Welcome to Zyxel Community!

    From your description, I think you are talking about the BPDU guard which we have already had the feature that you may configure on NCC.

    You may go to "SWITCH > Configure > Switch ports > (Choose ports) > STP guard" to configure.

    Hope it helps.
