message displayed is the oldest message in the buffer. To clear the c ontents o f the buffer, use the clear
logging privileged EXEC com ma nd.
To disable logging to the console, use the no logging console global configuration command. T o disable

Step 3 logging host Log me ssages to a UNIX syslog server host.
For host, specify 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.
For complete syslog server configuration steps, see th e “C onfiguring
UNIX Syslog Servers” section on page 23-10.
Step 4 logging file flash:filename
[max-file-size] [min-file-size]
[severity-level-number | type]
Store log me ssages in a file in Flash memory.
•For filename, enter the log message filename.
•(Optional) For max-file-size, specify t h e m axim um loggi ng file size.
The ran ge is 4096 to 214 748364 7. The default is 4069 bytes.
•(Optional) For min-file-size, specify the minimum logging file size.
The ran ge is 1024 to 214 748364 7. The default is 2048 bytes.

lower levels.
Step 5 end Return to privileged EXEC mode.
Step 6 terminal monitor Log me ssage s to a no nc onsole term ina l du ring the cur rent se ssion .
