		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/RSP0/CPU0:router(config)# logging console	• See Table 4-2for 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/RSP0/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 4-2for 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/RSP0/CPU0:router(config)# commit
Step 7
		end	Ends the configuration session and returns to EXEC
			mode.
		Example:
		RP/0/RSP0/CPU0:router(config)# end
Step 8
		show logging	Displays the messages that are logged in the buffer.
		Example:
		RP/0/RSP0/CPU0:router# show logging

Examples

In the following example, basic message logging is configured:

RP/0/RSP0/CPU0:router# configure

RP/0/RSP0/CPU0:router(config)# logging 10.1.1.1

RP/0/RSP0/CPU0:router(config)# logging trap debugging

RP/0/RSP0/CPU0:router(config)# logging console emergencies

RP/0/RSP0/CPU0:router(config)# logging buffered 1000000

RP/0/RSP0/CPU0:router(config)# commit

RP/0/RSP0/CPU0:router(config)# end

RP/0/RSP0/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
