Embodiment
Embodiment one
The method flow diagram of the acquisition fault message that Fig. 1 provides for the embodiment of the present invention one.The embodiment of the present invention is applicable to fault detect during alignment dynamic host configuration protocol DHCP server request distributing IP address in terminal, as shown in Figure 2, when terminal 20 reaches the standard grade request dispatching IP address, broadcast a DHCP DISCOVER to Access Network to wrap, wrap backward Dynamic Host Configuration Protocol server 22 and forward DHCP DISCOVER when dhcp relay agent 21 listens to DHCP DISCOVER and wrap, or do not forwarded by dhcp relay agent 21 and directly receive DHCP DISCOVER by Dynamic Host Configuration Protocol server 22 and wrap; It is mutual that information during Dynamic Host Configuration Protocol server 22 wraps according to DHCP DISCOVER and certificate server 23 carry out certification, after certification by certificate server 23, in the address realm that Dynamic Host Configuration Protocol server 22 is never leased, select an IP address encapsulation in DHCP OFFER message, and DHCP OFFER message is sent to dhcp relay agent 21, by dhcp relay agent 21, DHCP OFFER message is sent to terminal 20.In the process of terminal request distributing IP address, there will be fault causes terminal to obtain the failure of IP address, its failure cause includes but not limited to: the network failure between terminal and Dynamic Host Configuration Protocol server, Dynamic Host Configuration Protocol server equipment fault, network failure between Dynamic Host Configuration Protocol server and certificate server, certificate server equipment fault, user name authentication error or cipher authentication mistake, network access server port numbers (NAS-port-ID) authentication error and Dynamic Host Configuration Protocol server address pool runs out of resource sets, and concrete process fault detection is as follows:
Step 101, terminal send the DHCP request message being used for request dispatching IP address to dynamic host configuration protocol DHCP server;
After terminal is reached the standard grade, to dynamic host configuration protocol DHCP server or the DHCP request message being used for request dispatching IP address by dhcp relay agent to Dynamic Host Configuration Protocol server transmission, DHCP request message can be specifically DHCP DISCOVER message, includes user name, password and terminal positional information in described DHCP DISCOVER message.
Step 102, receive the DHCP that described Dynamic Host Configuration Protocol server returns and reply DHCP OFFER message, described DHCP OFFER message comprises failure indication information and failure-description information.
It is mutual that Dynamic Host Configuration Protocol server carries out certification according to the DHCP request message received and certificate server, if there is fault in verification process, then Dynamic Host Configuration Protocol server returns DHCP based on the fault occurred to terminal and replys DHCP OFFER message, and described DHCP OFFER message comprises failure indication information and failure-description information.
Step 103, obtain described failure indication information and described failure-description information.
Described failure indication information in terminal acquisition DHCP OFFER message and described failure-description information, described failure indication information is used to indicate terminal and there occurs fault of reaching the standard grade, and described failure-description information is for describing concrete failure cause of reaching the standard grade.
Carry concrete failure-description information in the DHCP OFFER message that the embodiment of the present invention returns to terminal at Dynamic Host Configuration Protocol server, concrete failure cause of reaching the standard grade can be determined fast, the fault and assisted network keeper quick solution is reached the standard grade according to failure-description information.
