Use the line vty line-number command to specify which vty
lines are to have synchronous logging enabled. You use a vty
connection for configurations that occur through a Telnet
session. The range of line numbers is from 0 to 15.

You can change the setting of all 16 vty lines at once by entering:
line vty 0 15
Or you can change the setting of the single vty line being used for
your current connection. For example, to change the setting for vty
