Here is what they mean:

no pass means that there is no line password configured for this line.

login local means that the login process will look for user ID and password configured on the local router (or switch) to use for authentication.

exec-timeout 30 means that you will have 30 minutes of inactivity before the router (or switch) will terminate the session because of inactivity.

transport input ssh means that remote sessions will be accepted that use SSH but remote sessions that use telnet will not be accepted.
