7.6 Disabling MAC Address Learning
If a fixed device is connected to an interface, you can disable MAC address learning on the
interface. This prevents other devices from accessing the interface and improves device security.
7.6.1 Establishing the Configuration Task
Before disabling MAC address learning, familiarize yourself with the applicable environment,
complete the pre-configuration tasks, and obtain the data required for the configuration. This
will help you complete the configuration task quickly and accurately.
Applicable Environment
As shown in Figure 7-2, an interface of the Switch is connected to a server. To protect the server,
configure the server MAC address as a static MAC address, disable MAC address learning on
the interface, and configure the interface to discard the packets with unknown MAC addresses.
The configuration prevents other servers or terminals from accessing the interface and improves
network stability and security.
