Configuring System Message Logging

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.
Command
Step 1 configure terminal
Step 2
service timestamps log uptime
or
service timestamps log datetime [msec] [localtime]
[show-timezone]
Step 3 end
Step 4 show running-config
Step 5
copy running-config startup-config
To disable time stamps 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
(Switch-2)
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 (Switch-2)

Enabling and Disabling Sequence Numbers in Log Messages

Because there is a chance that more than one log message can have the same time stamp, you can display
messages with sequence numbers so that you can unambiguously see a single message. By default,
sequence numbers in log messages are not displayed.
Beginning in privileged EXEC mode, follow these steps to enable sequence numbers in log messages.
This procedure is optional.
Command
Step 1 configure terminal
Step 2 service sequence-numbers
Step 3

Depending on the options selected, the time stamp can
include the date, time in milliseconds relative to the local
time-zone, and the time zone name.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
