VTY Access List Control

[m. jean stockton]

I am not sure about the correct commands for vty access control.  Is the following command correct to permit any device from network 192.88.54.0 to establish a virtual terminal session with the router?   line vty 0 4  access-list 12 permit 192.88.54.0  0.0.0.255     line vty 0 4 access-class 12 in     thanks     mjs
