FIELD: computer equipment.
SUBSTANCE: invention relates to computer engineering. Disclosed is a method of transmitting information on functions of an OpenFlow switch, which includes: after receiving, by the OpenFlow switch, messages with a request for information on ports transmitted by the OpenFlow controller, transmitting port group identifiers for those port groups to which each of the ports of the OpenFlow switch belongs, to OpenFlow controller, or transmission of port group identifiers for those ports groups, to which each of ports specified by OpenFlow controller belongs, into OpenFlow controller, wherein groups of ports are obtained by grouping ports with different functions in the OpenFlow switch based on one or more types of functions, and each of the port groups has a group of ports identifier.
EFFECT: providing OpenFlow controller transmission of information on ports of OpenFlow switch.
