Chapter 21 Configuring System Message Logging
The
logging buffered
global configuration command copies logging
messages to an internal buffer. The buffer is circular, so newer messages
overwrite older messages after the buffer is full.
•
To display the messages that are logged in the buffer, use the
show
logging
privileged EXEC command. The first message displayed is the
oldest message in the buffer.
•
To clear the contents of the buffer, use the
clear logging
privileged
EXEC command.
•
To disable logging to the console, use the
no logging console
global
configuration command.
•
To disable logging to a file, use the
no logging file [severity-
level-number | type]
global 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:
1.
Enter global configuration mode.
configure terminal
2.
Enable log timestamps.
The first command enables timestamps on log messages, showing the time
since the system was restarted.
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.
service timestamps log uptime
or
service timestamps log datetime [msec] [localtime]
[show-timezone]
3.
Return to privileged EXEC mode.
