The following example applies a standard ACL to control vty access. It permits any device on network 192.168.1.0 0.0.0.255 to establish a virtual terminal session with the router. Of course, the user must know the appropriate passwords to enter user mode and privileged mode. This example assumes that the protocol used to exchange with the router is Telnet; however, other protocol can be filtered by the access-class command, such as Secure Shell (SSH).

R1(config)# access-list 12 permit 192.168.1.0 0.0.0.255

!

R1(config)# line vty 0 4

R1(config-line)# access-class 12 in
