How does an enterprise network perform IP-MAC binding?

For corporate office Lans, the benefits of IP-MAC binding are obvious. However, in the process of specific implementation, enterprises should carry out the implementation in a planned and purposeful manner according to the characteristics of their respective local area networks and administrative means.

First of all, obtain the support of management and issue administrative orders.

If there is no corresponding administrative order, employees will constantly try to manually modify the IP to circumvent supervision. This leads to network problems such as continuous IP address conflicts. Therefore, in terms of administrative orders, we need to do the following:

1. It is forbidden to modify IP privately.

two。 It is forbidden to connect routers, portable wifi and other devices.

Once the above behaviors are found, combined with certain means of punishment, the work burden of technical means can be reduced.

Secondly, choose a reasonable IP-MAC binding technology.

In principle, the device on which the DHCP is assigned is bound on that device. But in the actual process, there may be some problems and deficiencies in the functional implementation of each device, so we can only analyze the specific problems. Move the DHCP to the gateway device as far as possible, and bind the static IP on the gateway, which can cooperate with the Internet behavior management and flow control, and the effect is better. As shown below:

There are too many clients to enter one by one, and you can import all of them directly.

Of course, there are other IP-Mac binding methods. Please refer to:

1. Local area Network IP-MAC binding Scheme

two。 How does the switch implement ip-mac binding?

3. Local area network IP address and MAC address binding, cross-segment IP-MAC binding
