Step 103: the IP address of all service ports on configuration testing port T and the router makes test port T and all service ports can use at the IP layer state, and has the available route of the IP address that arrives test port T in the routing table of assurance router;
Step 104: go up the configuration loopback at other all service ports except that service port 1 (being that service port 2 is to service port N) of router, the flow that flows out from current port can be flowed back to again work as front port; The configuration loopback can be realized also can realization being set by internal command by external fiber;
Step 105: on test port T, dispose a flow, and the purpose IP address and/or the source IP address of flow are set;
Above-mentioned steps 102 to step 105 can be carried out also and can carry out simultaneously in no particular order in proper order one by one;
Step 106: at all service port configuration flow classification, detailed process is as follows on router:
At first according to flow purpose IP address that disposes on the tester and/or source IP address configuration ACL (Access ControlList, Access Control List (ACL)), promptly at the purpose IP address of flow and/or the rule of the multiple identification of source IP address regulation IP message, then the part rule among the ACL being generated one group of rule according to the certain rules combination is traffic classification, can discern the IP message that meets a certain category feature with traffic classification;
Step 107: the Flow Behavior of each service port of configuration on router, i.e. the IP address and the outgoing interface of next jumping of the IP message of this service port of appointment arrival; Because make flow can return tester, not only to specify next jumping of the IP message that arrives this service port to be other service port of router, the IP address that is next jumping is the IP address of other certain service port of router such as port M, and outgoing interface is the port numbers of this service port M; And to make next jumping of the IP message that arrives each service port different, that is to say that next jumping of the IP message that arrives two service ports can not be same service port; Be each service port and all dispose different Flow Behaviors, so just do not have service port on the shelf, guaranteed that all service ports all have flow to flow into and outflow;
If for example having specified the IP address of next jumping of the IP message that arrives service port 2 is the IP address of service port 6, the IP address of next jumping that then arrives the IP message of service port 5 just can not be the IP address of service port 6, must be appointed as other also IP address of unspecified service port;
Step 108: the traffic classification and the Flow Behavior that configure are organized into Flow Policy, and on the Inbound of all service ports of router, enable Flow Policy, and the priority height of the priority ratio routing table of Flow Policy is set.
Step 109: after finishing above-mentioned configuration, start tester and send the good flow of configured in advance, because the priority height of the priority ratio routing table of Flow Policy, so pay the utmost attention to Flow Policy, can flow through according to this flow of Flow Policy and to return tester behind all service ports of router, tester is analyzed test result according to actual needs.
Referring to Fig. 2, the flow through flow process of all service ports of router of above-mentioned flow is specific as follows:
At first be that the service port 1 that docks with test port T receives this flow, find next to jump according to the Flow Policy on this service port Inbound and be the service port 2 of router, then from service port 2 these flows of output; Owing to be provided with loopback on the service port 2, flow flows out and can flow into from service port 2 again from service port 2; Find next to jump according to the Flow Policy on service port 2 Inbound equally and be the service port 3 of router, then from service port 3 these flows of output; The rest may be inferred, it is snakelike that flow is become, after arriving last service port N, because having specified outgoing interface in the Flow Policy on the service port N Inbound is service port 1, the IP address of next jumping is the IP address of the test port T of the tester that docks with router, then flow is from the output of professional port one and turn back to the test port T of tester, thereby all service ports that guaranteed router all run flow, and all has flow to flow on each service port and flow out.
