Configuring System Message Logging
How to Configure System Message Logging
Command
1. configure terminal
2. logging buffered [size]
3. logging host
4. logging file flash:filename
[max-file-size [min-file-size]]
[severity-level-number | type]
5. end
6. terminal monitor
Purpose
Enters global configuration mode.
Logs messages to an internal buffer on the switch. The range is 4096 to
2147483647 bytes. The default buffer size is 4096 bytes.
If the switch fails, the log file is lost unless you had previously saved it to
flash memory. See Step 4.
Note: Do not make the buffer size too large because the switch could run
out of memory for other tasks. Use the show memory privileged EXEC
command to view the free processor memory on the switch. However,
this value is the maximum available, and the buffer size should not be set
to this amount.
Logs messages to a UNIX syslog server host.
host—Specifies the name or IP address of the host to be used as the
syslog server.
To build a list of syslog servers that receive logging messages, enter this
command more than once.
Stores log messages in a file in flash memory.

filename—Enters the log message filename.

(Optional) max-file-size—Specifies the maximum logging file size.
The range is 4096 to 2147483647. The default is 4096 bytes.

(Optional) min-file-size—Specifies the minimum logging file size. The
range is 1024 to 2147483647. The default is 2048 bytes.

(Optional) severity-level-number | type—Specifies either the logging
severity level or the logging type. The severity range is 0 to 7. By
default, the log file receives debugging messages and numerically
lower levels.
Returns to privileged EXEC mode.
Logs messages to a nonconsole terminal during the current session.
Terminal parameter-setting commands are set locally and do not remain
in effect after the session has ended. You must perform this step for each
session to see the debugging messages.
