Configuring The Unix System Logging Facility - Cisco 3845 - Security Bundle Router Software Manual

Configuring System Message Logging
The local7 keyword specifies the logging facility to be used; see
information on the facilities. The debug keyword specifies the syslog level; see
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.
Create the log file by entering these commands at the UNIX shell prompt:
Step 2
$ touch /var/log/
$ chmod 666 /var/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.
Command
Step 1
configure terminal
Step 2
logging host
Step 3 logging trap level
Step 4 logging facility facility-type
Step 5
end
Step 6
show running-config
Step 7
copy running-config startup-config
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.

command more than once.
Limit messages logged to the syslog servers.
Be default, syslog servers receive informational messages and lower. See
