The router configuration is easy; it is the logging server that requires
a little work. To start you need to run syslog. On UNIX this is
accomplished by starting the syslogd daemon with specific flags:
OS Daemon Logfile Root Location
BSDI /sbin/syslogd -n /usr/var/log
SunOS /usr/etc/syslogd -n /var/log
Linux /usr/sbin/syslogd -n /var/log
Solaris /usr/sbin/syslogd -n /var/log
The syslog daemon gets its configuration information from
/etc/syslog.conf. This file will need to be edited to reflect how you
want syslog to handle your router's log messages.
Syslog decides how to handle a message by looking at the incoming
message's facility and severity level pair. Each message has a facility
level pair associated with it. The message's value pair is defined by
the program or service issuing the message, using syslog's defined
facility and severity levels. The IOS uses syslog's standard severity
values to classify messages and uses syslog facility local7 by default.
There are 10 different syslog facility definitions:
auth Authorization system
cron Cron/at facility
daemon System daemons
kern Kernel
local0–7 Local use
lpr Line printer system
mail Mail system
news Usenet news
syslog Syslog itself
user User process
