Configuring System Message Logging
To disable synchronization of unsolicited messages and debug output, use the no logging synchronous

Enabling and Disabling Time Stamps on Log Messages
By default, log messages are not time-stamped.
Beginning in privileged EXEC mode, follow these steps to enable time-stamping of log messages. This
procedure is optional.

(Optional) For level severity-level, specify the message severity
level. Messages with a severity level equal to or higher than this
value are printed asynchronously. Low numbers mean greater
severity and high numbers mean lesser severity. The default is 2.
