Embodiment
In embodiments of the present invention, the test scene of testing as required, select the corresponding business card, obtain the register that service card in the network equipment is controlled, change by the state of software, realize the state of the part or all of interface in the described service card is changed according to the state of this register to this register.
Utilize the state of the part or all of interface in the described service card to realize out test scene, in this test scene, utilize BFD agreement or fastfeeling function that the described network equipment is tested.
The handling process of the described method that the network equipment is tested of the embodiment of the invention comprises the steps: as shown in Figure 1
Step 1-1, the state of hardware register of control service card in the network equipment is changed, realize the state of interface in the service card is changed, realize out various test scenes.
In the time need carrying out beginning test of various complexity to the network equipment, such as, whether the forwarding of link in the network equipment or IP route be communicated with detect, to available detection the whether of the static routing in the network equipment, to the network equipment detection of giving out a contract for a project, the link of the network equipment is carried out various quick change detection based on BFD or fastfeeling or the like.
At first, the test scene of testing is as required chosen the service card in the corresponding network device, obtains the hardware register information that this service card is controlled.Then, change, the state of hardware register changed by the assignment of software to this hardware register, thus realize in this service card partly or entirely the state of interface change.According to the part or all of state of interface in this service card, just can realize this service card insertion, extract, various situations such as not on the throne, link down, and then realize out the test scene that above-mentioned needs are tested.
Step 1-2, in the various test scenes of realizing out, utilize test protocol that the network equipment is tested.
The state of part or all of interface in according to service card behind the test scene of realizing out testing, just can utilize BFD agreement or fastfeeling function etc. that the network equipment is tested in this test scene.
Introduce a concrete application example of the described method of the embodiment of the invention below.
Such as, in the networking of the network equipment that needs shown in Figure 2 are tested, link A-B-D-F is a reserve link, and A-C-E-F is an active link, and present embodiment is tested the switching services process between above-mentioned active link and the reserve link.
The embodiment of the invention is chosen the break simulation that router E in the networking shown in Figure 2 carries out active link, the master chip of supposing the interface card use of this router E is 88E1011, the offset address of the control register that this master chip is powered is 0x00, bit11 position in this control register be used to control master chip 88E1011 power supply connection and close, the 26S Proteasome Structure and Function of this bit11 is described as shown in Figure 3, the value of bit11 is that 0 expression is powered to master chip 88E1011, is that 1 expression is cut off the power supply to master chip 88E1011.
The embodiment of the invention arrives by the software transmitting order to lower levels and drives, by driving the value of the bit11 in the above-mentioned control register is put 1, so, just to the master chip 88E1011 outage of the interface card of above-mentioned router E, the state of the total interface in the interface card of router E just is down (interruption), being connected just between router E and extraneous other network equipment interrupted, and the state of above-mentioned active link is not just for being communicated with.So, just can the BFD agreement or the fastfeeling function carry out switching services test between the main/slave link.
In the above-described embodiments, can carry out Long-distance Control to the state of the interface in the interface card of router E by software, thereby can the interface line of the interface card of router E not plugged or docking port sticks under the situation of row plug, realizing the interruption and the connection of the Link State of router E.And then realize out various test scenes, can carry out various quick switch tests based on BFD or fastfeeling.
The structural representation of the described device that the network equipment is tested of the embodiment of the invention comprises as shown in Figure 4 as lower module:
