inquiring and updating the output port in the working state in the adjustment information;
and adjusting the output weight of the output port based on the updated adjustment information and a preset load balancing algorithm.
7. The method according to claim 2, wherein before reading an ip address list of a second device pre-stored in the first device and sending the first topology to the ip address, the method further includes:
and converting the first topology information into a character string in a preset format.
8. The method for managing network switching devices according to claim 7, further comprising, after the obtaining the second topology information of the second device:
checking the character string of the second topological information based on a preset format to judge whether the character string is legal or not;
and if the character string is legal, converting the character string into the second topology information.
9. A network switching equipment management device is characterized by comprising the following modules:
the first acquisition module is used for enabling a first management card to read first topology information from first equipment, and the first equipment comprises a plurality of communication ports for receiving and transmitting data;
the second acquisition module is used for acquiring second topology information of the second equipment;
an information generation module that generates adjustment information based on the first topology information and the second topology information;
and the adjusting module is used for adjusting the weight of the communication port of the first equipment in the load balancing algorithm according to the adjusting information.
10. A server comprising a memory, a processor and a program stored on the memory and executable on the processor, wherein the processor when executing the program implements a network switching device management method according to any one of claims 1 to 8.
11. A terminal readable storage medium, having a program stored thereon, wherein the program, when executed by a processor, is capable of implementing a network switching device management method according to any one of claims 1 to 8.
