FIELD: radio engineering, communication.
SUBSTANCE: invention relates to telecommunications, namely to identification of multiport device ports. The method of identification of multiport device ports of Ethernet interface, includes: reception by the multiport device of the Ethernet interface of the message transmitted by the module of network device port; getting information on the switch chip or on the network processor (NP) of the respective network device according to the information on input port of the message transmitted by the port module and pre-set to the mapping table, while the pre-set mapping table sets the compliance between the information on input port and the information on the switch chip or NP; saving data on the switch chip or NP in the message transmitted by the port module for modification of the named message, and transmission of this message to the respective switch chip or NP so that the switch chip or NP is able to receive the information on input port according to the information on the switch chip or NP.
EFFECT: elimination of loss of capacity without decrease of switch capacity.
