How to configure a black hole MAC address
To prevent hackers from attacking user devices or networks through MAC addresses, the MAC addresses of untrusted users can be configured as black hole MAC addresses. When the device receives a message that the destination MAC or the source MAC address is a black hole MAC address, it is discarded directly. The switch provides two ways to configure black hole MAC addresses: global black hole MAC addresses and VLAN-based black hole MAC addresses.
1. In the system view, configure the MAC address 0000-0012-0034 as the global black hole MAC.
