Concrete, in the time that the GVRP of equipment D protocol processes is abnormal, P1 port and the equipment of equipment DThe P2 port of D can cause dynamic vlan 100 quilts extremely due to the GVRP protocol processes of this equipment DNullify; In addition, in the time that the GVRP of equipment D protocol processes is abnormal, equipment E send Join message withoutMethod sends in equipment C, equipment B, and therefore the P1 port of equipment B and the P1 port of equipment C is movingState VLAN100 also can be because the GVRP protocol processes of equipment D causes being canceled extremely.

Because the link between equipment E and device A does not have fault, therefore equipment E sends out by port P2The implicit expression CCM message sending can send in device A, device A can receive Level be 3 hiddenFormula CCM message, and confirm that corresponding CFD testing result (between device A and equipment E) is for normal.Because the dynamic vlan 100 of the P1 port of equipment D is canceled, therefore equipment E sends out by port P2The demonstration CCM message sending can not send in device A, and device A can not receive that Level is 3Demonstration CCM message, and confirm corresponding GVRP testing result (between device A and equipment E)For failure.

Because the GVRP protocol processes of equipment D is abnormal, therefore equipment D can not send implicit expression CCM reportLiterary composition and demonstration CCM message. Further, due to device A, can not to receive Level be 2 implicit expressionCCM message, therefore confirms that corresponding CFD testing result (between device A and equipment D) is unsuccessfully.Can not receive Level due to device A is 2 demonstration CCM message, therefore confirms corresponding GVRPTesting result (between device A and equipment D) is unsuccessfully.

Because the link between equipment C and device A does not have fault, therefore equipment C sends out by port P2The implicit expression CCM message sending can send in device A, device A can receive Level be 1 hiddenFormula CCM message, and confirm that corresponding CFD testing result (between device A and equipment C) is for normal.Because the dynamic vlan 100 of the P1 port of equipment B is canceled, therefore equipment C sends out by port P2The demonstration CCM message sending can not send in device A, and device A can not receive that Level is 1Demonstration CCM message, and confirm corresponding GVRP testing result (between device A and equipment C)For failure.

Because the link between equipment B and device A does not have fault, therefore equipment B is sent out by port P2The implicit expression CCM message sending can send in device A, device A can receive Level be 0 hiddenFormula CCM message, and confirm that corresponding CFD testing result (between device A and equipment B) is for normal.In addition, the demonstration CCM message that equipment B sends by port P2 can send in device A, equipmentA can receive that Level is 0 demonstration CCM message, and confirms that corresponding GVRP testing result (establishesBetween standby A and equipment B) be normal.

Based on above-mentioned analytic process, device A can obtain the testing result shown in table 5.

Further, utilize the testing result shown in table 5, can analyze as follows:

The CFD testing result that is 3 based on Level, can show that device A arrives the link between equipment ENormally, and because device A is normal to the link between equipment E, illustrate that the whole link of network does not haveOccur extremely, now prove to have the GVRP agreement of equipment to occur abnormal. Further, based on LevelBe 2 CFD testing result, can show that device A arrives link between equipment D and occurs extremely, this is differentOften because not sending implicit expression CCM message, equipment D causes; The CFD that is 1 based on Level detectsAs a result, can show that device A arrives link between equipment C normal; The CFD that is 0 based on Level inspectionSurvey result, can show that device A is normal to the link between equipment B. In addition be 3 based on Level,GVRP testing result, can show that GVRP agreement occurs abnormal; The GVRP that is 2 based on LevelTesting result, can show that GVRP agreement occurs abnormal; The GVRP that is 1 based on Level detects knotReally, can show that GVRP agreement occurs abnormal. Further, the CFD that is 2 based on Level detectsResult and Level are 2 GVRP testing result, and can reach a conclusion is: the GVRP on equipment DAgreement occurs abnormal, causes port cannot register dynamic vlan 100, then causes the CFD of other LevelTesting result is that link is normal, but GVRP testing result is abnormal.

(2) when equipment GVRP(is for detection of GVRP agreement) normal, when network link is abnormal, vacationIf the link between equipment C and equipment D disconnects, can cause the situation shown in Fig. 5 to occur. Now, establishThe P2 port of the P1 port of standby B, the P1 port of equipment C, equipment D all can be because link disconnectsCause dynamic vlan 100 to be canceled, therefore device A is determined corresponding GVRP testing result and CFDTesting result is unsuccessfully, as shown in table 6.
