Chapter 5 Configuring Additional Router Features

Configuring Logging and Logging Correlation

DETAILED STEPS

	Command or Action	Purpose
Step 1
	configure	Enters global configuration mode.
	Example:
	RP/0/RP0/CPU0:router# configure
Step 2
	logging {ip-address hostname}	Specifies a syslog server host to use for system logging.
	Example:
	RP/0/RP0/CPU0:router(config)# logging 10.1.1.1
Step 3
	logging trap severity	Limits the logging of messages sent to syslog servers to
		only those messages at the specified level.
	Example:	• See Table 5-2for a summary of the logging severity
	RP/0/RP0/CPU0:router(config)# logging trap debugging	levels.
Step 4
	logging console [severity]	Logs messages on the console.
		• When a severity level is specified, only messages at
	Example:	that severity level are logged on the console.
	RP/0/RP0/CPU0:router(config)# logging console	• See Table 5-2for a summary of the logging severity
	emergencies
		levels.
Step 5	logging buffered [severity buffer-size]	Copies logging messages to an internal buffer.
		• Newer messages overwrite older messages after the
	Example:	buffer is filled.
	RP/0/RP0/CPU0:router(config)# logging buffered	• Specifying a severity level causes messages at that
	1000000
		level and numerically lower levels to be logged in an
		internal buffer. See Table 5-2for a summary of the
		logging severity levels.
		• The buffer size is from 4096 to 4,294,967,295 bytes.
		Messages above the set limit are logged to the
		console.
Step 6
	commit	Commits the target configuration to the router running
		configuration.
	Example:
	RP/0/RP0/CPU0:router(config)# commit
Step 7
	end	Ends the configuration session and returns to EXEC
		mode.
	Example:
	RP/0/RP0/CPU0:router(config)# end
Step 8
	show logging	Displays the messages that are logged in the buffer.
	Example:
	RP/0/RP0/CPU0:router# show logging
