Description
Technical field
The present invention relates to the communications field, in particular to a kind of sending method, exchange chip and ethernet router of mirror image message.
Background technology
Fig. 1 is the general ethernet router configuration diagram according to correlation technique.
As shown in Figure 1, this router is mainly by CPU, last one or more ethernet controllers that carry of CPU, and exchange chip constitutes.Exchange chip links to each other with ethernet controller on the CPU through the ether port of self; This mouthful is called UPLINK mouth (being uplink port) on the exchange chip, and (the route mouth here only is meant and is used for transmitting data, possibly be 2 layers of forwarding and other ports on the exchange chip expand to the route mouth; Also possibly be 3 layers of forwarding; Just be used to be different from mirror port, say something), like route mouth A-D among the figure; Usually let a mouth on the exchange chip be mirror port (mirror port is not participated in message and is transmitted, just be used for the transmission on other interfaces, receive message all the mirror image portion send from this interface).
Expand a plurality of route mouths and only use an ethernet controller to connect exchange chip; Though can work; But the low performance requirement that does not reach the middle and high end router of performance; Use other other route mouths of ethernet controller expansion on the CPU through regular meeting, like the independent route mouth E among the figure, F (saying so of independent route mouth is used to be different from the route mouth of exchange chip expansion).
Fig. 2 is the configuration schematic diagram according to exchange chip under the general ethernet router framework of correlation technique.
Among Fig. 2; Two ports that the exchange chip inner dotted line links to each other are in same VLAN (Virtual Local Area Network; Abbreviate Vlan as), and the port on the exchange chip be connected with outside vlan the expression port belong to this vlan, by figure can know that the UPLINK mouth can be in 5 vlan simultaneously; Be operated in trunk mouth pattern, detailed configuration sees the following form 1:
Table 1
| Vlan | The port that belongs to this vlan |
| VLAN1 | The UPLINK mouth, route mouth A |
| VLAN2 | The UPLINK mouth, route mouth B |
| VLAN3 | The UPLINK mouth, route mouth C |
| VLAN4 | The UPLINK mouth, route mouth D |
| VLAN5 | The UPLINK mouth, mirror port |
Also might belong to a vlan by a plurality of route mouths; (it doesn't matter for this to form one 2 layers exchange; Irrelevant with the problem that we will explain), the key point of this kind router architectures configuration is to be in a plurality of vlan (being operated in the trunk pattern) except that the UPLINK mouth, the port that router externally provides (comprises all route mouth A-D; And mirror port) all only joins an acquiescence vlan; Be in a vlan, only carry out message and transmit (these ports that externally provide adopt the untag mode simultaneously, and the UPLINK mouth does not adopt untag) through this vlan and uplink.Whether adopt untag to be meant that message sends the vlan tag that whether peels message before off from the port of exchange chip, untag will peel vlan tag off exactly, and does not adopt untag not peel vlan tag off.
The message that the exchange chip external interface of this Ethernet routing framework receives can be submitted to CPU with the vlan tag that goes up the port acquiescence through the UPLINK mouth automatically; CPU is with vlan tag to know that message is to receive from which interface according to message; Message the enterprising walking along the street of CPU by and the decision from which interface transmit; If outgoing interface is the port on the exchange chip; Can give the vlan tag of outgoing interface on this message band when CPU sends message, thus message can in this vlan of exchange chip, transmit, and send from the outgoing interface of route decision.
The port of this Ethernet routing framework exchange chip receives message; Can learn the source MAC+VID of key=message; Result=receives the port of message; And add the MAC+VID list item of learning to exchange chip inner MAC+VID and show (if also do not learn, just first message can be learnt).The inner MAC+VID table of exchange chip is seen table 2 in detail:
Table 2
| Key | Result |
| The source MAC+VID of message | Receive the port of message |
The message of exchange chip is transmitted and just is based on this table; Just transmit the purpose MAC that is based on message; The purpose MAC+VID of the key=message of promptly searching, message can send from the port (being the corresponding result of key) that finds, and has a problem here; If the port that finds is exactly the port that receives this message, this message can be dropped and can not transmit.
And this problem just in time can appear in a kind of application of router; The mirror port of this router will be accomplished the message of the route mouth that mirror image is all; The reception of the independent route mouth outside the port of just expanding on the exchange chip, sending message all will be by mirror image; Wherein the purpose of mirror image is in order to monitor, and whether monitoring has what illegal content etc. through the flow content of these interfaces, and the mirror port of router can be received on the relevant watch-dog in the practical application.
Transmission on the independent route mouth E, reception message situation: general Ethernet independence route mouth E sends the source MAC of message and the target MAC (Media Access Control) address of reception message is identical, all is the MAC Address of independent route mouth itself.The MAC Address of supposing independent route mouth E itself is MAC1; If the target MAC (Media Access Control) address of the transmission message of independent route mouth E is MAC2; If it is MAC3 that independent route mouth E receives the source MAC of message, purpose MAC, source MAC such as the following table 3 of the transmission of so independent route mouth E, reception message:
Table 3
| Purpose MAC | Source MAC | |
| Sending direction | MAC2 | MAC1 |
| Receive direction | MAC1 | MAC3 |
And mirror image will send through the UPLINK mouth top sending direction, two kinds of messages of receive direction exactly from mirror port.
Fig. 3 is the sketch map according to the transmission on the independent route mouth E of the general ethernet router of correlation technique, reception message mirror.
By shown in Figure 3, substep diagram step comprises the steps that S1 is to step S5:
Step S1: by the transmission message of mirror image, it is Vlan5 that the CPU in the router puts by the transmission message vlan tag of mirror image, sends to the UPLINK mouth of exchange chip then for (independent route mouth); This message (DA; SA) be (MAC2, MAC1), vlan tag is VLAN5; (annotate DA, destination MAC address, the MAC Address of feeling the pulse with the finger-tip; SA, source MAC address refers to source MAC, MAC1, MAC2 or the like are the code names of MAC Address, down together).
Step S2:UPLINK receives this message, and exchange chip is learnt Key=MAC1+VLAN5, and the MAC+VID list item of Result=UPLINK mouth adds in the MAC+VID table of self;
Step S3: exchange chip can not find out the list item of Key=MAC2+VLAN5, and message is broadcasted away from the mirror port that belongs to VLAN5 with UPLINK;
Step S4: by the reception message of mirror image, it is VLAN5 that the CPU in the router puts by the reception message vlan tag of mirror image, sends to the UPLINK mouth of exchange chip then for (independent route mouth); This message (DA; SA) be (MAC1, MAC3), vlan tag is VLAN5;
Step S5: exchange chip uses Key=MAC1+VLAN5 inquiry MAC+VID table (can find this list item; Be exactly the list item that step 2 is added); Find that outlet is UPLINK mouth itself, will dropping packets, so just do not reach the independently purpose of the reception message of mouth of mirror image.
This system architecture has following problem: under original router generalization configuration; Mirror port only can belong to a vlan (like Fig. 1) as an external interface (generally directly connecing PC or server); The router message that will send from this interface like this, router will add message the vlan tag of mirror port, could send message from this mouth; If MAC Address is both as the source MAC of message; Occur as the target MAC (Media Access Control) address of some messages simultaneously again, the port that will occur acquiring purpose MAC like this is exactly the port that receives this message, thus message can not exchange chip inner transmit by and the problem that abandon.(situation that above-mentioned MAC Address MAC1 comes to this, it is the source MAC of independent route mouth E, also can appear in the target MAC (Media Access Control) address if the two-way mirror picture will inevitably both appear in the source MAC).
To the mirror image independence route mouth transmission simultaneously of exchange chip in the correlation technique, reception message, thereby the problem that causes message not to be dropped inner forwarding of exchange chip does not propose effective solution at present as yet.

Fig. 6 is the sketch map according to the transmission on the independent route mouth E of the ethernet router of the embodiment of the invention, reception mirror image message.
Ethernet router according to the embodiment of the invention comprises CPU and exchange chip.
As shown in Figure 6, this method may further comprise the steps:
Step S601: by the transmission message of mirror image, it is Vlan5 that CPU puts by the transmission message vlan tag of mirror image, sends to the UPLINK mouth of exchange chip then for (independent mouthful), this message (DA, SA) be (MAC2, MAC1), vlan tag is Vlan5;
Step S602:UPLINK receives this message, and exchange chip is learnt Key=MAC1+Vlan5, and the MAC+VID list item of Result=UPLINK mouth adds them in the MAC+VID table of self to;
Step S603: exchange chip can not find out the list item of Key=MAC2+Vlan5, and message is broadcasted away from the mirror port that belongs to Vlan5 with UPLINK;
Step S604: by the reception message of mirror image, it is Vlan6 that CPU puts by the reception message vlan tag of mirror image, sends to the UPLINK mouth of exchange chip then for (independent mouthful), message (DA, SA) be (MAC1, MAC3), vlan tag is Vlan6;
Step S605:UPLINK receives this message, and exchange chip is learnt Key=MAC3+Vlan6, and the MAC+VID list item of Result=UPLINK mouth adds it in MAC+VID table of self to;
Step S606: same, exchange chip can not find out the list item of Key=MAC1+Vlan6, and message is broadcasted away from the mirror port that belongs to Vlan6 with UPLINK; Reached the purpose of sending this message like this.
Preferably, the method is not limited to independent port mirror image message and sends, and can receive and transmit the message of a MAC as source MAC as long as relate to a switching chip port, also can transmit the message as purpose MAC with this MAC simultaneously.
In the present invention, exchange chip has two operations for the message that receives, and one is MAC address learning, and one is that message is transmitted.Wherein, MAC address learning carries out according to source MAC (being SA), and the message forwarding is carried out according to purpose MAC (being DA).
And for the study of MAC, exchange chip is only just learnt when a MAC Address appears at message for the first time as source MAC, and just for same MAC Address, MAC address learning is only learnt once (because learnt, just not learnt naturally) again.
It is that each message all need carry out that but message is transmitted; Because exchange chip receives a message from a port; Must this message be sent (comprising discard processing) from a port; Alternatively, how determining from which port to send is exactly that message is transmitted the processing that will do.
In the present invention; MAC address learning is exactly an exchange chip with the source MAC (being SA) of the message that receives on the switching chip port and Vlan id as key; The port numbers that receives the exchange chip of this message is added in exchange chip internal mac-VID table as result; Wherein, the inner MAC+VID of exchange chip shows as shown in table 5: (VID is writing a Chinese character in simplified form of vlan id, down together).
Table 5
| ?Key | Result |
| The source MAC+VID of message | Receive the port of message |
Above-mentioned mentioning; It is according to purpose MAC that message is transmitted; So the vlan id that exchange chip was got purpose MAC and the message of message when message was transmitted looks into this top MAC-VID as key and shows, if found, the result of the list item that is found so is exactly the port that this message will be transmitted; Exchange chip only sends this message from the port of this appointment; If do not find, exchange chip can be broadcasted this message in the indicated vlan of the vlan of this message id, just from all are in the port of this vlan, message is sent.
In addition; Though be to use source MAC and VID in the time of study; And be to use purpose MAC and vid when searching, no matter be source MAC or purpose MAC, when depositing in the exchange chip in the MAC-VID table; A MAC Address all is the data of 6 bytes, shown in the MAC+VID table 6 of embodiment of the invention exchange chip inside:
Table 6
| Key | Result |
| MAC+VID | Switching chip port |
In the present invention, that mirror image receives that message adds is another VID, removes to look into the MAC-VID table with the purpose MAC and the new VID of message; Do not search and can hit (because mirror image sends message; The MAC Address of learning is identical, but vlan id is different, so key is just inequality; Key is identical for list item; Be identical), message can be broadcasted away (and mirror port is exactly a port that belongs to this new vlan) in this new vlan like this, sends the purpose that mirror image receives message so can reach.
Top step S602 and step S605 are used for explaining why acting this patent is; Because particularly step S602 has explained that the key that uses when MAC-VID list item that it is learnt and step 6 are tabled look-up is inequality; The key of step S602 is MAC1+Vlan5; And the key that step S606 tables look-up is MAC1+Vlan6, and both are different, can not hit so table look-up.
From above description, can find out that the present invention has realized making that the message of any route mouth can both send from mirror port on the router, message content information is undistorted.
