It's belong a Point to Point Connection over a EAPS-Ring. We have created a VMAN on the ring and add the port untagged on the vman.
The cutomer have on his side a cisco with "switchport port-security maximum 1" defined.
Now if the ring broken then the eaps send arp-flush and at the same time on the cisco-side/customer goes the port down because of more the 1 MAC
Could someone explain me the write Setting on the customer / untag port side that the customer don't get more the 1 MAC ̈-Adresse from the port out in case of a ring broken or complete !
