368 CHAPTER 19: ACL CONFIGURATION
Controlling Telnet using Source MAC
This configuration can be implemented by means of Layer 2 ACL, which ranges from
4000 to 4999. For the definition of ACL, refer to ACL part.
Configuration Example
Network requirements
Only Telnet users from 10.110.100.52 and 10.110.100.46 can access the switch.
