ABSTRACT:
An Ethernet switching and forwarding method, and at least one Ethernet forwarding mode of standard Ethernet forwarding, multiplex Ethernet forwarding, layer-3 routing and forwarding, across-VLAN multicast forwarding plane, point-to-point VLAN forwarding, or point-to-point double VLAN forwarding. The method includes: an Ethernet message entering a user side port or a network side port; processing, by the port, the message to provide the message with a VLAN tag allocated uniformly by the port; determining, by the port, a forwarding mode for the message and sending the message to a corresponding forwarding plane; determining, by the forwarding plane, an egress port of the message and processing the specific Ethernet control message in accordance with a control message capturing policy table; and forwarding the message to the egress port and encapsulating the message in accordance with an attribute table of the egress port.
