Description
Technical Field
The invention relates to a switch communication system in the field of data communication, in particular to a method for automatically discovering two-layer network switching equipment and remotely configuring and managing IP.
Background
Switches typically have a dedicated management port, called an out-of-band management port, which is typically a stand-alone port, used only for device management, and a more common management approach is to use an in-band management port, which is configured to allow data access and use as a management device. In data communication network systems, in-band data management is typically used to manage devices, and because in-band management acts on the data ports, the data network is off-the-shelf, remote connection management devices can be used in a remote management manner.
A common switch will have a default IP address at the factory, it is common practice for a switch with an independent out-of-band management port to have a default out-of-band management IP, but not create a default out-of-band management port. If the switch is a switch without an out-of-band management port, the default would create interface valn 1 and configure a default IP on this port. The new device is either the same as the management IP of all devices or has no in-band management port configured, so it must be manually run to the place where the device is located to connect the serial port or the out-of-band management port in a direct connection manner, and the configuration management IP requires significant labor costs for the operator.
