Multi-core processor and method for multiplexing network management port thereof

摘要

The present invention provides a multi-core processor and a method for multiplexing a network management port thereof, and relates to the field of processor technologies. The multi-core processor includes: a network management port, an initializing unit, and N control planes, where the initializing unit is configured to select one control plane as a management control plane from the N control planes, and enable a network management port packet reception interrupt only for the management control plane; the management control plane is configured to receive a packet from the network management port or another control plane, and according to characteristic information of each control plane and characteristic information of the received packet or a packet to be sent, send the packet to a CPU of this control plane or to another control plane and/or transmit the packet through the network management port. The multi-core processor and the method for multiplexing the network management port thereof according to the present invention, by enabling the network management port packet reception interrupt for the management control plane, finally implement multiplexing of the network management port between multiple control planes.
