Configuring System Message Logging
To disable synchronization of unsolicited messages and debug output, use the no logging synchronous
[level severity-level | all] [limit number-of-buffers] line configuration command.
Enabling and Disabling Timestamps on Log Messages
By default, log messages are not timestamped.
Beginning in privileged EXEC mode, follow these steps to enable timestamping of log messages:
To disable timestamps for both debug and log messages, use the no service timestamps global
configuration command.
This example shows part of a logging display with the service timestamps log datetime global
configuration command enabled:
*Mar 1 18:46:11: %SYS-5-CONFIG_I: Configured from console by vty2 (10.34.195.36)
This example shows part of a logging display with the service timestamps log uptime global
configuration command enabled:
00:00:46: %LINK-3-UPDOWN: Interface Port-channel1, changed state to up
Step5 show running-config Verify your entries.
Step6 copy running-config startup-config (Optional) Save your entries in the configuration file.

Step1 configure terminal Enter global configuration mode.
Step2 service timestamps log uptime
or
service timestamps log datetime [msec] [localtime]
[show-timezone]
Enable log timestamps.
The first command enables timestamps on lo g messages,
showing the time since the system was rebooted.
The second command enables timestamps on log messages.
Depending on the options selected, the timestamp can
include the date, time in milliseconds relative to the local
time zone, and the time zone name.
Step3 end Return to privileged EXEC mode.
Step4 show running-config Verify your entries.
Step5 copy running-config startup-config (Optional) Save your entries in the configuration file.
