Static user access network control method based on MAC address

Abstract

The invention relates to a MAC address-based static user access network controlling method, configuring static user information on network access equipment, where the user MAC address is configured as quasi-MAC address; as the user connects to the network, responding to the ARP request message or initiatively sending the ARP request message, updating the user quasi-MAC address into user actual-MAC address by using the network access equipment according to the MAC address information carried in the message. It can make the user use the same MAC but use different IP addresses to connect to the network in different physical positions, better meeting special requirements of some users. Simultaneously, it can reduce workload of configuring person, where the configuring person need not configure user MAC address as configuring static user information.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for controlling static user access to a network based on a MAC address. Background technique [0002] At present, there are mainly two ways for user VLAN access to the network, one is that the user is set to automatically obtain an IP address and obtain relevant network parameters through DHCP (Dynamic Host Configuration Protocol); the other is that the user manually sets relevant network parameters, Such as IP address, DNS (domain name server), etc., the latter we call static users. Users who access the network in static user mode must ensure that the configuration information for the user is maintained on the network access device. The configuration information usually includes the user's IP address, user port, user VLAN ID, and user MAC address. For a user who accesses the network as a static user, after the corresponding configuration information is co...

Problems solved by technology

[0003] From the above description, it can be seen that the configuration method for static users increases the workload of the configuration personnel on the one hand: before each configuration, the administrator needs to know the actual MAC address of the network card, and needs to enter a long MAC address, which is a very heavy workload. Large and error-prone; on the other hand, this static binding method makes users access to the network inflexible. Once the administrator configures a static user, it is impossible for the user to use another IP address or in another physical location. Access to the network, and after the user replaces the network card, the administrator must also be notified to change the corresponding configuration

Therefore, the existing technology cannot meet some special needs of users in the process of accessing the network. For example, users hope to use the same MAC address to access the network from different ports of the network access device, that is, use the same MAC address in different physical locations. address for network access
