1. A communication device comprising:
a plurality of ports configured to transmit and receive frames to and from another device; a switch configured to transfer the frames to another port based on identification information of the frames; and a central processing unit configured to perform first control on the communication device, wherein the central processing unit performs, as the first control, operations of:
receiving the frames transferred from the switch;acquiring frames to be duplicated based on a validity of a setting as a management end point to a port which is included in the plurality of ports and belongs to a group integrating a plurality of physical communication lines of the plurality of ports;duplicating the frames to be duplicated,assigning the identification information indicating a corresponding port to a plurality of duplicated frames;outputtinq the plurality of duplicated frames to the switch; andperforming second control in accordance with control information included in one duplicated frame of the plurality of duplicated frames.
