Problems solved by technology
[0029] The present invention is proposed in view of the problem that the switching chip cannot simultaneously mirror the sending and receiving messages of independent routing ports, thus causing the messages to be discarded because they cannot be forwarded inside the switch. Therefore, the main purpose of the present invention is to provide a mirror image message Sending method, switching chip and Ethernet router, to solve the above problems

Embodiment Construction
[0055] Considering that the switch chip cannot mirror the packets sent and received by independent routing ports at the same time, so that the packets cannot be forwarded and discarded inside the switch, the embodiment of the present invention provides a method for sending mirrored packets, a switch chip and an Ethernet router . Wherein, the method includes: the switching chip receives the image sending message, wherein the image sending message carries the first virtual local area network identification; the switching chip forwards the mirror sending message through the first virtual local area network; the switching chip receives the image receiving A message, wherein the mirrored received message carries the identifier of the second virtual local area network; the switching chip forwards the mirrored received message through the second virtual local area network.
[0056] It should be noted that, in the case of no conflict, the embodiments in the present application and the...

The invention discloses a sending method of a mirror image message, a switch chip and an Ethernet router. The method comprises the following steps of: receiving a mirror image sending message by using the switch chip, wherein the identification of a first virtual local area network is carried in the mirror image sending message; transmitting the mirror image sending message by using the switch chip through the first virtual local area network; receiving a mirror image receiving message by using the switch chip, wherein the identification of a second virtual local area network is carried in the mirror image receiving message; and transmitting the mirror image receiving message by using the switch chip through the second virtual local area network. By using the method, a message of a routing port on the router can be normally sent out from a mirror image port, and the content of the message is undistorted.
Description
technical field [0001] The invention relates to the field of communications, in particular to a method for sending mirrored messages, a switch chip and an Ethernet router. Background technique [0002] figure 1 It is a schematic diagram of a general Ethernet router architecture according to related technologies. [0003] Such as figure 1 As shown, the router is mainly composed of a CPU, one or more Ethernet controllers on the CPU, and a switching chip. The switch chip is connected to the Ethernet controller on the CPU through one of its own Ethernet ports. This port on the switch chip is called the UPLINK port (that is, the uplink port), and the other ports on the switch chip are extended as routing ports (here the routing port It just refers to the one used to forward data, which may be Layer 2 forwarding or Layer 3 forwarding. It is just used to distinguish it from the mirror port to illustrate the problem). The port is a mirror port (the mirror port does not participa...
