We have devices that doesn't show their mac when the link comes up. This is a common practise in network enabled doorlockers like the Paxton or Salto brands . These access devices have to be triggered by for example an arp request.
How to configure mac-based secured ports on extreme switches in such a way that arp requests (or any traffic) is allways allowed exiting, obviously before the port is succesfully authorized?
HP Procurve switches solved this with: aaa port-access 7 controlled-direction in which allowes traffic to exit the switch on port 7
So far we haven't found a sollution to this in EXOS.
