Chapter 24 Configuring System Message Logging
Configuring System Message Logging
The local7 keyword specifies the logging facility to be used; see
Table 24-4 on page 24-13
for
information on the facilities. The debug keyword specifies the syslog level; see
Table 24-3 on page 24-9
for information on the severity levels. The syslog daemon sends messages at this level or at a more severe
level to the file specified in the next field. The file must already exist, and the syslog daemon must have
permission to write to it.
Step 2
Create the log file by entering these commands at the UNIX shell prompt:
$
touch /var/log/
cisco.log
$
chmod 666 /var/log/
cisco.log
Step 3
Make sure the syslog daemon reads the new changes:
$
kill -HUP `cat /etc/syslog.pid`
For more information, see the man syslog.conf and man syslogd commands on your UNIX system.
Configuring the UNIX System Logging Facility
When sending system log messages to an external device, you can cause the switch to identify its
messages as originating from any of the UNIX syslog facilities.
Beginning in privileged EXEC mode, follow these steps to configure UNIX system facility message
logging. This procedure is optional.
To remove a syslog server, use the no logging host global configuration command, and specify the syslog
server IP address. To disable logging to syslog servers, enter the no logging trap global configuration
command.
Table 24-4
lists the UNIX system facilities supported by the software. For more information about these
facilities, consult the operator’s manual for your UNIX operating system.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
logging host
Log messages to a UNIX syslog server host by entering its IP address.
To build a list of syslog servers that receive logging messages, enter this
command more than once.
Step 3
logging trap level
Limit messages logged to the syslog servers.
Be default, syslog servers receive informational messages and lower. See
Table 24-3 on page 24-9
for level keywords.
Step 4
logging facility facility-type
Configure the syslog facility. See
Table 24-4 on page 24-13
for
facility-type keywords.
The default is local7.
Step 5
end
Return to privileged EXEC mode.
Step 6
show running-config
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
