A port in Neutron is a logical connection of a virtual network interface to a subnet and network. Ports can be associated with virtual machine instances, DHCP servers, routers, firewalls, load balancers, and more. Ports can even be created simply to reserve IP addresses from a subnet. Neutron stores port relationships in the Neutron database and uses that information to build switching connections at the physical or virtual switch layer through the networking plugin and agent.
