Chapter 25 Configuring System Message Logging
Configuring System Message Logging
Beginning in privileged EXEC mode, follow these steps to change the level and history table size
defaults. This procedure is optional.
When the history table is full (it contains the maximum number of message entries specified with the
logging history size global configuration command), the oldest message entry is deleted from the table
to allow the new message entry to be stored.
To return the logging of syslog messages to the default level, use the no logging history global
configuration command. To return the number of messages in the history table to the default value, use
the no logging history size global configuration command.
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.
