The enumeration 'portIdMacAddr(3)' represents a port identifier based on a unicast source MAC address, which has been detected by the agent and associated with a particular port. The enumeration 'portIdPtopoGenAddr(4)' represents a port identifier based on a network address, detected by the agent and associated with a particular port.
