VTY ACLs

To limit Telnet and SSH connections to the switch, apply access lists on a virtual terminal line (VTY). See Virtual terminal line ACLs for more information.

For VTY ACLs, there is no implicit deny rule. If none of the configured conditions match, the default behavior is to permit. If you need to deny traffic that does not match any of the configured conditions, explicitly configure a deny statement.
