That is to say; When detecting many main frames between above-mentioned two stacked switch and detect cables and do not connect, what connect between the stack port of above-mentioned two stacked switch through above-mentioned two stacked switch piles up the cable transmission service message, piles up protocol massages and administrative message.
Particularly; The state of many main frames detection port of another stacked switch that the stacked switch in the pile system can be confirmed to be connected with this stacked switch in this pile system according to the physical signalling that receives; If the state of many main frames detection port of another stacked switch that this stacked switch is connected with this stacked switch is operate as normal (up); And the many main frames detection messages between this stacked switch and another stacked switch that this stacked switch is connected can normal transmission, and then this stacked switch can confirm that this stacked switch and many main frames between another stacked switch detect cables and are connected; If the state of many main frames detection port of another stacked switch that this stacked switch and/or this stacked switch connect is fault (down); And can't transmit many main frames detection messages between this stacked switch and another stacked switch that this stacked switch is connected, then this stacked switch can confirm that this stacked switch and many main frames between another stacked switch detect cables and are not connected.
Fig. 4 is that the present invention is through piling up the sketch map of an embodiment of cable transmission administrative message; As shown in Figure 4; Be not connected many main frames between many main frames detection port of stacked switch 1 and stacked switch 2 and detect cables, stacked switch 1 and stacked switch 2 pile up the cable transmission service message, pile up protocol massages and administrative message through what be connected between the stack port.
Administrative message is a kind of Ethernet message that carries privately owned label, can be two layer message or three-tier message.Administrative message is in the inner use of manufacturer, the protocol massages that carries out equipment control, and the protocol type that the protocol type of the employing of administrative message and existing common message adopt is all inequality, therefore can be through protocol type identification administrative message.It mainly is that the exchange chip that relies on stacked switch is provided with the register list item and realizes that stacked switch receives message from port.If on exchange chip, can not discern the register list item of administrative message to the port setting, this port can't the transfer management message so.In the prior art; Many main frames detection port is handled as the common network port; On exchange chip, can not discern the register list item of administrative message to the setting of many main frames detection port, therefore can't be through many main frames detection port transfer management message.The embodiment of the invention is directed against the register list item that the setting of many main frames detection port can be discerned administrative message on exchange chip, make many main frames detection port not only can transmit many main frames detection messages, can also the transfer management message.
Fig. 5 is the sketch map of the present invention through two embodiment of main frame detection port transfer management message; As shown in Figure 5; Be connected with many main frames between many main frames detection port of stacked switch 1 and stacked switch 2 and detect cable; Stacked switch 1 piles up the cable transmission service message and piles up protocol massages through what be connected between the stack port with stacked switch 2, and stacked switch 1 detects cable transmission many main frames detection messages and administrative message with stacked switch 2 through the many main frames that are connected between many main frames detection port.
Be example with stacked switch 1 transmission and receiving management message below, the process through many main frames detection port transfer management message is described.
When sending administrative message, the central processing unit of stacked switch 1 (Central Processing Unit; Hereinafter to be referred as: CPU) after the packaged administrative message; This administrative message is sent to the exchange chip of stacked switch 1; Receive after this administrative message; The exchange chip of stacked switch 1 can not carry out extra encapsulation to this administrative message; But directly the many main frames detection port through stacked switch 1 sends this administrative message, is connected because many main frames detection port of stacked switch 1 only detects cables with many main frames detection port of stacked switch 2 through many main frames, and therefore the administrative message that sends of the many main frames detection port through stacked switch 1 can quilt be sent to many main frames detection port of stacked switch 2 through many main frames detection cables; As shown in Figure 5, thus can realize sending administrative message through many main frames detection port.
When the receiving management message; Many main frames detection port of stacked switch 1 receives after the message, at first can this message be sent to the exchange chip of stacked switch 1, receives after the message; The exchange chip of stacked switch 1 can be according to the register list item corresponding with many main frames detection port stacked switch 1 that be provided with on this exchange chip; Confirm whether above-mentioned message is administrative message, and, above-mentioned message is handled according to above-mentioned register list item.
In the present embodiment, the above-mentioned register list item corresponding with many main frames detection port of stacked switch 1 is for discerning the register list item of administrative message; Particularly, above-mentioned register list item can be quick filter engine (Fast Filter Processor; Hereinafter to be referred as: FFP) list item, this FFP list item comprises matched rule field and processing mode field.In the FFP list item that can discern administrative message corresponding with many main frames detection port of stacked switch 1; The value of matched rule field can be set to the protocol type of administrative message; Perhaps also can be with in the source port of source MAC, target MAC (Media Access Control) address, source IP address, purpose IP address, TCP/UDP and the destination interface one or more, and the protocol type of administrative message is set to the value of matched rule field together; The value of processing mode field can be set to send to CPU.
Like this; Receive after the message that many main frames detection port of stacked switch 1 sends; The exchange chip of stacked switch 1 can be resolved this message earlier, obtains the characteristic information of this message, for example: the protocol type of this message; In addition, the characteristic information of above-mentioned message can also comprise one or more in source port and the destination interface of source MAC, target MAC (Media Access Control) address, source IP address, purpose IP address, TCP/UDP of message; The exchange chip value of matched rule field in characteristic information and the above-mentioned FFP list item of this message relatively then; If the two is identical, then this exchange chip can confirm that the message that receives is an administrative message, next; Exchange chip can be according to the value of processing mode field in the above-mentioned FFP list item; This administrative message is sent to the CPU of stacked switch 1, and the CPU of stacked switch 1 can receive above-mentioned administrative message like this, thereby can realize through many main frames detection port receiving management message.
The administrative message that the embodiment of the invention provides receives and sending method; Through many main frames detection port transfer management message; The clogging that transmission causes to administrative message when having avoided the business datum amount big; Both make full use of the bandwidth of many main frames detection port, saved a priority of exchange chip again.
In addition; Comprising in the pile system that two stacked switch are example, in the embodiment of the invention, if the cable that piles up that connects originally between above-mentioned two stacked switch breaks off or breaks down; And the many main frames detection cables between above-mentioned two stacked switch still keep connecting; Then after detecting the opposite end stacked switch through many main frames detection port, pile system gets into many Host Status automatically, detects rule according to many main frames and only in pile system, stays a main frame; Close the common port of other main frames, only stay stack port and many main frames detection port and normally open.Referring to Fig. 6, Fig. 6 piles up the sketch map that cable breaks off an embodiment for the present invention, and is as shown in Figure 6; The cable that piles up between stacked switch 1 and the stacked switch 2 breaks off; But many main frames cable still keeps connecting, and after stacked switch 1 and the stacked switch 2 many main frames detection port through separately detected the opposite end, pile system got into many Host Status automatically; Detect rule according to many main frames and only in pile system, stay a main frame; For example: stacked switch 1, close the common port of stacked switch 2, the stack port and the many main frames detection port that only stay stacked switch 2 are normally opened.
In this case, in the prior art, owing to can not discern the register list item of administrative message to the setting of many main frames detection port in the exchange chip, therefore many main frames detection port only can be transmitted many main frames detection messages, and can not the transfer management message; Again owing to piling up the cable disconnection or breaking down; Administrative message and service message can't be through piling up cable transmission; And the protocol state machine between stacked switch heat is equipped with information through the administrative message transmission, therefore above-mentioned situation will cause protocol state machine heat between the stacked switch to be equipped with information can't be synchronous.Piling up after cable connects again or recover operate as normal, have to some stack members in the pile system are resetted owing to the protocol state machine gap between the stacked switch is excessive; It still is example with Fig. 6; In the prior art; Piling up after cable is connected again or recovers operate as normal between stacked switch 1 and stacked switch 2 because the protocol state machine gap between stacked switch 1 and the stacked switch 2 is excessive, need reset stacked switch 2.
But in the method that the embodiment of the invention provides; In the exchange chip of stacked switch, be directed against the register list item that the setting of many main frames detection port can be discerned administrative message; Under the situation of piling up the cable disconnection or breaking down; Still can continue the transfer management message between the stacked switch through many main frames detection port; As shown in Figure 6, though the cable that piles up between stacked switch 1 and the stacked switch 2 break off, still can be between stacked switch 1 and the stacked switch 2 through many main frames detection port transfer management message; Thereby can guarantee that protocol state machine heat between stacked switch 1 and the stacked switch 2 is equipped with transmission of Information and can interrupt, just the service message between stacked switch 1 and the stacked switch 2 and the transmission of piling up protocol massages have been interrupted.Like this; Piling up after cable recovers to be connected between stacked switch 1 and stacked switch 2; Because the protocol state machine between stacked switch 1 and the stacked switch 2 still keeps synchronous regime; Need not reset, only need open stacked switch 2 pent common ports and just can make overall stack fold the system restoration operate as normal stacked switch 2.
