1-14. (canceled)
A multi-core processor, comprising:
- a network management port;
- N control planes;
- and
- an initializing unit, wherein 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,
- wherein 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 either of characteristic information of the received packet and feature information of a packet to be sent, send the packet to a CPU of this control plane or to another control plane, or transmit the packet through the network management port, wherein N is a positive integer greater than or equal to 2.
A method for multiplexing a network management port of a multi-core processor, comprising:
- receiving, by a management control plane, a packet from a network management port or another control plane;
- and
- sending, by the management control plane according to characteristic information of each control plane and characteristic information of the received packet or a packet to be sent, the packet to a CPU of this control plane or to another control plane, or transmitting the packet through the network management port, wherein the management control plane is a control plane for which a network management port packet reception interrupt is enabled in N control planes of the multi-core processor, wherein N is a positive integer greater than or equal to 2.
