You will have to create a new which allows to cover all existing MACs and include new ones for future customers.
address resolution protocol is used when the switch used to build the dynamic mac address table.
BRIDGE
A switch would record multiple entries for a single switch port in its MAC address table if it does not contain the Mac address of a particular destination in the address table. It will broadcast to all ports besides the port where entry comes from.

A switch builds a MAC address table, which contains the MAC addresses of devices connected to its ports along with the corresponding port numbers. When a switch receives a data frame, it reads the source MAC address and updates its table if the address is not already present. To send data to a specific device, the switch looks up the destination MAC address in its table and forwards the frame out of the appropriate port associated with that address. If the destination address is not found, the switch broadcasts the frame to all ports except the one it received it on.
Power cycle the switch to clear all dynamically learned addresses, and the clear mac address table command will remove statically and dynamically configured table entires
by reading the source hardware address of a frame

Final Destination Address
sometimes when interface configured with a static IP address, which is not correct, the host does not communicate to the port, and switch has no MAC address. I've seen it just two days ago - had an Linux appliance with a static IP address configured on the interface. Plugged interface to the switch, port says "Connected", but no MAC address in the CAM table. After I changed an IP address to whatever it should be for the VLAN - NIC started to communicate, and MAC address appears on the port.
