Description

Conflict detection method, system, terminal and storage medium for static IP and dynamic IP

Technical Field

The invention relates to the technical field of servers, in particular to a method, a system, a terminal and a storage medium for detecting conflict between a static IP and a dynamic IP.

Background

Normally, the server BMC (Baseboard management Controller, BMC for short) IP plays an extremely important role in the test process. In the test work, the BMC generally performs IP allocation in a DHCP (dynamic host configuration protocol) environment, the IP is bound with the MAC, and different server BMCs have different MACs, so that in the DHCP environment, if all the server BMCs in the network use DHCP to acquire addresses, no IP address conflict is generated among the server BMCs.

In actual test work, the BMC IP is set to be static, for example: the static IP is manually set for the server BMC A, before setting, a tester can test the IP to be set so as to ensure that the IP does not conflict with other server BMCIPs, and as long as the server BMC is in a running state, the set IP can not be distributed to other server BMCs in a DHCP environment. However, the server BMC that sets the static IP is powered off after being used, and when other server BMCs acquire the IP in the DHCP environment, because the static IP is not running, a situation may occur in which the static IP is allocated to the other server BMCs as its dynamic IP according to the protocol, and at this time, the server BMC B has the dynamic IP, and when the server BMC a is powered on and powered on, the static IP of the server BMC a conflicts with the dynamic IP of the server BMC B. When the server BMC IP conflict is tested, great inconvenience is brought to the test, the test failure is caused, and the test efficiency is reduced.

FIG. 1 is a schematic flow diagram of a method of one embodiment of the invention. The execution subject in fig. 1 may be a collision detection system of static IP and dynamic IP.

As shown in fig. 1, the method 100 includes:

step 110, obtaining BMC port IP information through an IPMI interface and confirming that the port IP information comprises a static IP;

step 120, restarting the BMC and ping the special port IP and the shared port IP of the BMC;

step 130, judging whether the private port IP and the shared port IP are ping communication:

step 140, if yes, modifying the static IP in the BMC background;

and 150, if not, judging that the static IP has no conflict IP.

In order to facilitate understanding of the present invention, the following further describes the collision detection method for static IP and dynamic IP provided by the present invention by using the principle of the collision detection method for static IP and dynamic IP of the present invention and combining the process of performing collision detection on static IP and dynamic IP in the embodiment.

Specifically, the method for detecting a conflict between a static IP and a dynamic IP includes:

s1, obtaining IP information of a BMC port through an IPMI interface and confirming that the IP information of the port comprises a static IP.

And ensuring a test environment, connecting a network card with a network cable, and connecting an IPMI port with the network cable (acquiring a BMC IP).

Powering on and starting up, detecting whether the current BMC IP is a static IP, and checking the BMC shared port IP and the BMC private port IP by using an IPMI command: if the IP of the BMC private port and the IP of the shared port are both dynamic IPs, conflict detection is not needed; and if static IP exists between the BMC private port and the shared port IP, performing conflict detection.

And S2, restarting the BMC and performing ping operation on the special port IP and the shared port IP of the BMC.

And restarting the BMC, wherein the BMC IP cannot ping, and because the restart process can last for 90 seconds, the BMC dedicated port IP and the sharing port IP are subjected to ping operation after waiting for 90 seconds.

S3, judging whether the private port IP and the shared port IP are ping communication or not: if yes, modifying the static IP in a BMC background; if not, judging that the static IP has no conflict IP.

If the ping is not passed, it indicates that the static IP of the BMC has no IP conflict with other server BMCs.

If the ping is on, it indicates that there is a conflict between the BMC IP of the other server host (host B) and the BMC IP of the host, and at this time, further verification is performed, and the method includes:

and acquiring and recording the current test host (host A) log and FRU information. Taking the BMC private port as an example, if the private port BMC IP can ping (ping to the host B), at this time, a remote connection command is executed for the ping-enabled IP, and the log and FRU information of the host B are obtained and recorded, and compared with the log and FRU information of the host a, the information is found to be different, and it is further verified that the host a and the host B have IP conflict.

And detecting the conflicted IP, after the BMC is restarted, changing the IP in a background, firstly performing ping operation on the IP to be changed, and if the ping is not successful, setting the IP as a new BMC special interface IP. Or directly changing the static IP into a dynamic mode to obtain the dynamic IP again.

If the shared port also has IP conflict in the detection process, the shared port can be detected and changed by the same method.
