Huawei core switch configures mac address whitelist access
Huawei core switches are configured with a whitelist of mac addresses, allowing only terminals in the whitelist to access the specified VLAN.
For example:
only allow computers with mac address: 4557-ca30-75a1 to access vlan 101.
Log in to the core switch and find the mac address corresponding to the computer:
Or enter ipconfig /all in the cmd of the computer to check the mac address:
Configure the whitelist to
allow the mac address to access vlan 101 [SW-Core]user-bind static mac-address 4c57-ca30-74a1 vlan 101
Then turn on the source address restriction check on the vlan 101 interface:
[SW-Core]vlan 101
[SW-Core-vlan101]ip source check user-bind enable
After the restriction is turned on, computers with other mac addresses can obtain IP but cannot connect to the network.
