Optionally, following several scenes are mainly divided in some inventive embodiments, during practical application：
In the first scene：Server, which is required to report his or her problems within a prescribed time and in a prescribed place, accesses NPV forwarding units.
NPV forwarding units configure only in particular port local log-on, local log-on refer to server access interface The NPV proxy ports for belonging to same physical equipment log in.
As shown in figure 3, after it is determined that the first NPV proxy ports are unavailable, the NPV forwarding units abandon described the One link logs in message, and forbids the server log.In other words, after NPV proxy ports A is unavailable, NPV forwarding units This virtual link will not be established：From server access interface A->NPV proxy ports B->FCF ports B->FCF ports A->NPV generations Manage port C->WWP NC across stack FCoE virtual links, so as to save the bandwidth of stacking opening.
Logged under such a scene using the proxy port of protocol stack prioritizing selection this equipment, solve virtual link across more Individual physical equipment establishes problem.Simultaneously as without configuring multiple NPV examples, the configuration and saving of equipment can be simplified VLAN resources.
In second of scene：Server, which is required to report his or her problems within a prescribed time and in a prescribed place, accesses NPV forwarding units, is configured in NPV forwarding units only in particular port Local log-on.
Wherein, server access NPV forwarding units of requiring to report his or her problems within a prescribed time and in a prescribed place refer to that the major network card of server and standby network interface card are respectively connected to stack Two different physical equipments of system, form two independent forward-paths.Particular port include server access interface, NPV proxy ports and FCF ports, only refer in the configuration of NPV forwarding units in particular port local log-on：Sent by WWPN Link logs in message, can only be forwarded on the virtual link configured with the WWPN, and server incoming end corresponding with the WWPN Mouth and NPV proxy ports belong to same physical equipment, for example, server access interface A and NPV proxy port A belongs to same Individual physical equipment, then log in message by WWPNA link, server access interface A and NPV proxy port A can only be passed through Forwarding, it is impossible to forwarded by server access interface A and NPV proxy port B.Need not by by server access interface and NPV proxy ports are isolated with single example so that protocol stack side isolates, and to reach the foundation avoided across stacking link, passes through Required to report his or her problems within a prescribed time and in a prescribed place access using server.
Required to report his or her problems within a prescribed time and in a prescribed place in server under access scene, avoid mainly including following A＆B two schemes across stacking link establishment：
In option A：Require to report his or her problems within a prescribed time and in a prescribed place under access scene in server, only do not stepped on locally in particular port in the configuration of NPV forwarding units Record.
If local the first NPV proxy ports can use, then meeting prioritizing selection enters in the first NPV proxy ports Row logs in, but after it is determined that local the first NPV proxy ports are unavailable, the NPV forwarding units can be by described first Link logs in message and is converted to the first port discovery message, and is sent out the first port using the 2nd NPV proxy ports Existing message is sent to the FC forwarding units, the 2nd NPV proxy ports carried out temporarily with the first NPV proxy ports across Stack connection.After the confirmation message that the FC forwarding units return is received, the NPV forwarding units can be issued including described First server access interface to the 2nd NPV proxy ports routing iinformation, due to have been set up across stack virtual link, So after the first NPV proxy ports state is recovered, former forward-path will not be resettled again, server is also not sent further on Message is logged in, that is, will not be forwarded again by the first NPV proxy ports forward-path and log in message.
As shown in Fig. 4-1, when NPV proxy ports A is unavailable, NPV proxy ports A and NPV proxy ports B, which is stacked, to be connected, Formed across stacking virtual link：Server access interface A->NPV proxy ports B->FCF ports B->FCF ports A->NPV agent sides Mouth C->Server access interface C->WWPNC.
In option b：Due to may can be established across stacking link when NPV proxy ports are unavailable in option A temporarily, It is interim during to solve the problems, such as that NPV proxy ports are unavailable to establish across stacking link, it can be configured in NPV forwarding units only in spy Fixed end mouth local log-on.
After it is determined that the first NPV proxy ports are unavailable, the NPV forwarding units abandon first link and logged in Message, the server can constantly repeat to log in message in particular port transmission link.
When the first NPV proxy ports recover, the NPV forwarding units receive in the first server access interface After the second link that the server is sent logs in message, second link login message is converted into second port and finds report Text, and second port discovery message is sent to the FC forwarding units using the first NPV proxy ports；
After the confirmation message that the FC forwarding units return is received, the NPV forwarding units issue secondary route letter Breath, the secondary route information include the routing iinformation of the first server access interface to the first NPV proxy ports, In this case, FCoE flows will not be forwarded across stacking.
Such as the mechanism shown in Fig. 4-2, only existed by server access interface A message in the configuration of NPV forwarding units NPV proxy ports A is logged in.After it is determined that NPV proxy ports A is unavailable, the NPV forwarding units abandon link and log in message, Hereafter, the server can constantly repeat to log in message in server access interface A transmission links.
When NPV proxy ports A recovers, the NPV forwarding units receive the server in server access interface A and sent New link log in message after, new link login message is converted into port discovery message, and should using NPV proxy ports A Port discovery message is sent to the FC forwarding units；
After the confirmation message that the FC forwarding units return is received, the NPV forwarding units are issued including server Access interface A to NPV proxy ports A routing iinformation, by it is this pressure login mechanism it is possible to prevente effectively from FCoE flows across The forwarding of stacking.
Such scheme A and option b equally support server access interface and NPV proxy ports not in same physical equipment Scene, i.e., without by setting different instances come isolation protocol stack side, you can avoid across the foundation for stacking link, with existing machine System is compared, and on the premise of ensureing that server network interface card normally logs in, also more saves local network resource.
In the third scene：Server, which is required to report his or her problems within a prescribed time and in a prescribed place, accesses NPV forwarding units, is configured in NPV forwarding units only in particular port Local log-on.
After it is determined that the first NPV proxy ports are unavailable, the NPV forwarding units abandon first link and logged in Message, and forbid the server to be logged in by the first NPV proxy ports and the first server access interface.
The second link that the NPV forwarding units receive the server transmission in second server access interface logs in report Wen Hou, second link login message is converted into second port and finds message, and use accesses with the second server Second port discovery message is sent to the FC forwarding units by the 2nd NPV proxy ports corresponding to port.
After the confirmation message that the FC forwarding units return is received, the NPV forwarding units issue secondary route letter Breath, the secondary route information include the second server access interface to the routing iinformation of the 2nd NPV proxy ports.
As shown in figure 5, after NPV proxy ports A is unavailable, NPV forwarding units can forbid logging in message from server access Port A is forwarded.Logged in because server has been prohibited this paths from server access interface A- ＞ NPV proxy ports A, and NPV forwarding units are configured with fixed virtual link, and mandatory services device only logs in particular port, so server can only pass through clothes Business device access interface B sends new link and logs in message, and receiving the new link login of server transmission in server access interface B reports New link login message is converted to port discovery message by Wen Hou, NPV forwarding unit, then using NPV proxy ports B by the end Mouth finds that message is sent to the FC forwarding units；
After the confirmation message that the FC forwarding units return is received, the NPV forwarding units are issued including server Access interface B to NPV proxy ports B routing iinformation, by it is this pressure login mechanism and handover mechanism it is possible to prevente effectively from Forwarding of the FCoE flows across stacking.
