How does the switch implement IP-MAC bindings?

Many companies need to bind IP-MAC addresses for security reasons. IP-MAC bindings can be implemented in a variety of ways, and in this article I'll show you how the switches are Ip-mac bound.

#绑定该端口的mac和IP

User-bind mac-addr 001a-4d1e-3981 ip-addr 10.100.11.2

The number of users is a bit more convenient to set up on the gateway router. Such as:
