Chapter 70 Configuring System Message Logging
Configuring System Message Logging
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 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
Enabling and Disabling Sequence Numbers in Log Messages (Optional)
Because more than one log message can have the same timestamp, you can display messages with
sequence numbers so that you can unambiguously refer to a single message. By default, sequence
numbers in log messages are not displayed.
To enable sequence numbers in log messages, perform this task, which is optional.
To disable sequence numbers, use the no service sequence-numbers global configuration command.
This example shows part of a logging display with sequence numbers enabled:
000019: %SYS-5-CONFIG_I: Configured from console by vty2 (10.34.195.36)
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# service timestamps log uptime
or
Switch(config)# service timestamps log
datetime
[msec] [localtime] [show-timezone]
Enables log time-stamps.
The first command enables time-stamps on log messages,
showing the time since the system was rebooted.
The second command enables time-stamps 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.
Step 3
Switch(config)# end
Returns to privileged EXEC mode.
Step 4
Switch# show running-config
Verifies your entries.
Step 5
Switch# copy running-config startup-config
(Optional) Saves your entries in the configuration file.
