IP address allocation method and device

Abstract

The present application discloses an IP address allocation method and device, which relate to the field of communication technology. The access switch judges whether the destination port receiving the IP address request message sent by the DHCP client is a port configured with a fixed IP address segment allocation mode in advance; if so, Then in the IP address request message, add the identification information for identifying the configuration mode of the fixed IP address segment, and send the processed IP address request message to the DHCP server; The identification information of the DHCP client is assigned an IP address in a fixed IP address segment configuration mode. In the above method, when a device connected to a port configured with a fixed IP address segment allocation mode fails, a fixed IP address corresponding to the port can be assigned to the newly connected device, so that plug-and-play of the newly connected device can be achieved. Use, reduce the redeployment of terminal equipment failures in the network, and reduce the workload of operation and maintenance personnel.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to an IP address allocation method and device. Background technique [0002] In a larger network, with the continuous development of services, the number of terminal devices joining the network will increase. In the actual network operation and maintenance process, due to the large number of terminal devices connected to the network, the possibility of terminal device failure in the network increases. When a terminal device fails, a new terminal device is generally used to replace the faulty terminal device. , generally, after the replacement, the IP address of the new access terminal device needs to be re-deployed, especially in the case of a large number of terminals in the network, there will be a lot of cases where a fault needs to be re-deployed, and every Every redeployment requires the operation and maintenance personnel to reconfigure, which increases ...
