Configuring Logging and Logging Correlation

	Command or Action	Purpose
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

Examples

In the following example, basic message logging is configured:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# logging 10.1.1.1

RP/0/RP0/CPU0:router(config)# logging trap debugging

RP/0/RP0/CPU0:router(config)# logging console emergencies

RP/0/RP0/CPU0:router(config)# logging buffered 1000000

RP/0/RP0/CPU0:router(config)# commit

RP/0/RP0/CPU0:router(config)# end

RP/0/RP0/CPU0:router# show logging

Syslog logging: enabled (162 messages dropped, 0 flushes, 0 overruns)

Console logging: level emergencies, 593 messages logged

Monitor logging: level debugging, 0 messages logged

Trap logging: level debugging, 2 messages logged

Logging to 10.1.1.1, 2 message lines logged

Buffer logging: level debugging, 722 messages logged
