Controlling Telnet Users By Source Mac Addresses; Configuration Example - H3C S5120-SI Series Operation Manual

Controlling Telnet Users by Source MAC Addresses

This configuration needs to be implemented by Layer 2 ACL; a Layer 2 ACL ranges from 4000 to 4999.
For the definition of ACL, refer to ACL Configuration.
