The LED indicating a link - which has absolutely nothing to do with MAC addresses, frames, ACLs, ... - this is a much lower level. The PHY link establishment and retaining is complete independent of the transport of frames. 10BASE-T used regular link pulses, 100BASE-T uses a constant signal, 1000BASE-T and up uses pule bursts.
No link, no communication.
Unfortunately, the documentation does not make it clear what happens to the link LED if the Violation Shutdown happens.
Check the logs or the Port Status - there should be more information visible.
