OpenFlow ports are Ethernet ports which may be either physical or logical ports. A logical port is some sort of port that is not physical, such as a VLAN port, or an Ethernet tunneled port. Each port has an associated Port ID, which may not come from the reserved range of Port IDs. Additionally, a port has an Ethernet MAC address and human readable description. A ports configuration may be modified by an OpenFlow controller; however, its state is an indication of current link status and is read-only. Port properties include Ethernet features supported, operating speed and mode, and physical medium type (copper, fiber, pigeon, etc.).
