Configuring System Message Logging
Configuring UNIX Syslog Servers
The next sections describe how to configure the UNIX server syslog daemon and how to define the UNIX
system logging facility.
Logging Messages to a UNIX Syslog Daemon
Before you can send system log messages to a UNIX syslog server, you must configure the syslog
daemon on a UNIX server. This procedure is optional.
Log in as root, and perform these steps:
Note
Some recent versions of UNIX syslog daemons no longer accept by default syslog packets from the
network. If this is the case with your system, use the UNIX
man syslogd
command to decide what
options must be added to or removed from the syslog command line to enable logging of remote syslog
messages.
Step 1
Add a line such as the following to the file /etc/syslog.conf:
local7.debug /usr/adm/logs/
cisco.log
The
local7
keyword specifies the logging facility to be used; see
Table 29-4 on page 29-13
for
information on the facilities. The
debug
keyword specifies the syslog level; see
Table 29-3 on page 29-9
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.
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.
