Chapter 32 Configuring System Message Logging

Configuring System Message Logging

Beginning in privileged EXEC mode, follow these steps to enable configuration logging:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	archive	Enter archive configuration mode.
Step 3
	log config	Enter configuration-change logger configuration mode.
Step 4
	logging enable	Enable configuration change logging.
Step 5
	logging size entries	(Optional) Configure the number of entries retained in the configuration
		log. The range is from 1 to 1000. The default is 100.
		Note When the configuration log is full, the oldest log entry is removed
		each time a new entry is entered.
Step 6
	end	Return to privileged EXEC mode.
Step 7
	show archive log config	Verify your entries by viewing the configuration log.

This example shows how to enable the configuration-change logger and to set the number of entries in the log to 500.

Switch(config)# archive

Switch(config-archive)# log config

Switch(config-archive-log-cfg)# logging enable

Switch(config-archive-log-cfg)# logging size 500

Switch(config-archive-log-cfg)# end

This is an example of output for the configuration log:

Switch# show archive log config all

44	14	temi@vty4	exit
45	16	temi@vty5	interface GigabitEthernet5/0/1
46	16	temi@vty5	switchport mode trunk
47	16	temi@vty5	exit

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.
