The method comprises the following steps: when mirroring is conducted on an optical port connected with an optical interface module in the PHY chip, an electrical port connected with an electrical interface in the PHY layer enters a connection state, an interface multiplexer in the PHY chip is controlled, and then a data message received by the optical port or sent through the optical port is forwarded to the electrical port, so that port mirroring of the electrical port to the optical port is achieved; and when the electrical port conducts mirroring, the optical port enters a connection state, the port multiplexer is controlled, and then a data message received by the electrical port or sent through the electrical port is forwarded to the optical port, so that port mirroring of the optical port to the electrical port is achieved.

Description
Technical field
The present invention relates to Ethernet, relate in particular to a kind of Port Mirroring implementation method and device of ethernet device.
Background technology
Ethernet is by U.S. electric and (the Institute of Electrical andElectronics Engineers of Electronic Engineering Association, IEEE) standardized a kind of local area network (LAN) interconnection technique, the major technique standard of Ethernet defines in the normative document IEEE 802.3 of IEEE issue, (Media Access Control, MAC) functional mode of chip, layering and branch block message have specific definition in IEEE802.3 for ethernet physical layer (PHY) chip and media interviews control.The Ethernet of mainstream applications connects media optical fiber and unshielded twisted pair (Unshielded Twisted Paired, UTP) two kinds.Wherein optical fiber and UTP respectively have its advantage: the optical fiber price is relatively costly, but single channel optical fiber has transmission range far away usually, can reach 40 kilometers; And the UTP cable is more cheap, but because mainly be subjected to decaying isoparametric influence, can only transmit more than 100 meter usually, so a lot of ethernet device has all added photoelectric multiplexing port in order to realize the flexibility in this application.So-called photoelectric multiplexing port is actually two ports, and they are operated in optical fiber interface pattern and UTP electrical interface pattern respectively, realize normal exchange work but synchronization has only a port can be linked into exchange chip.These two ports are by providing with a slice PHY chip simultaneously.
PHY chip with photoelectric multiplexing port mainly comprises 4 modules, is respectively: MAC interface module, interface multiplexer, optical interface module and electrical interface module.A kind of design of common photoelectric multiplexing interface (has 2 photoelectric multiplexing ports) as shown in Figure 1, wherein:
The optical interface module connects optical port (as optical fiber interface), and be connected to interface multiplexer by the F line, electrical interface module connects electric port (as the UTP interface), and be connected to interface multiplexer by the T line, interface multiplexer is connected to MAC functional module in the exchange chip by the MAC interface module by the COM line, and can only have an interface module (optical interface module or electrical interface module) to be connected with the MAC functional module of exchange chip inside by the interface multiplexer decision at synchronization.The MAC functional module of exchange chip inside realizes different media interviews controlled function when distinct interface module in the PHY chip is connected, and defines in normative document IEEE 802.3 about the detail of media interviews control.
In order to carry out the monitoring of network flow monitoring, network supervision, virus monitoring or bad data, need to realize the Port Mirroring function of ethernet device.So-called Port Mirroring (English is commonly called as Mirror) is exactly with the transmission of a port (source mirror port) or intact the duplicating to another port (purpose mirror port) of data that receives.In the prior art, the ethernet device Port Mirroring is realized by exchange chip, promptly by the forwarding rule of exchange chip is set, realizes the function of a particular port toward another particular port mirror image.The implementation procedure of this mirror image is as shown in Figure 2:
After the data message of source mirror port (monitored port B) enters the PHY chip, be sent to exchange chip, exchange chip is according to the forwarding rule of setting then, message is forwarded to correct purpose receiving port (the A port among Fig. 2), simultaneously, owing to opened the image feature of B port, so the intact portion that duplicates of message that exchange chip also can be received the B port is to the purpose mirror port (policing port C) on the right to the C port.
In the prior art, another kind of mirror image scheme is on data image to a policing port with a plurality of ports, realize of the monitoring of a port to a plurality of ports, the problem that this mirror image scheme is introduced is that flow sum when a plurality of monitored ports is during greater than the policing port flow, blocking must appear in policing port, and this may cause important loss of data.And monitored port crucial port such as cochain normally, the flow of these ports is bigger usually, uses the disadvantage of a plurality of ports of port monitoring to embody more obviously at this moment.
In sum, there is following shortcoming in the ethernet device Port Mirroring in the prior art:
1) port utilization ratio is low.Policing port (purpose mirror port) and monitored port (source mirror port) have taken the port of a MAC and a PHY chip respectively separately, make need introduce effective port cost when realizing the Port Mirroring function.
2) increased the bandwidth burden of exchange chip.In the art methods, all must use exchange chip to participate in transmitting, redundant monitor data need be finished by exchange chip and duplicate, and has taken the switching bandwidth resource of exchange chip.
3) in the monitoring of carrying out one-to-many (being mirror image) is used, when monitored port flow is big, can't realize 100% monitoring, can occur blocking and the policing port packet loss.
