In general, techniques are described for dynamic port configuration with an interconnection system (IS) to streamline a process for port ordering and reduce port configuration and interconnection services provisioning times. In one example, an IS includes at least one interconnection facility and a programmable network platform (PNP), the at least one interconnection facility including: a network switch fabric having at least one network device and ports; and a customer cage for a customer of an IS provider for the IS, wherein the PNP is configured to, in response to a port verification request initiated by the customer to verify a port of the ports that is cross-connected to a customer network in the customer cage to provide connectivity with the network switch fabric: obtain an indication of a port configuration for the port; and output the indication of the port configuration for the port for display to the customer.
