Chapter 38 Configuring IP Unicast Routing

Monitoring and Maintaining the IP Network

Beginning in privileged EXEC mode, follow these steps to manage authentication keys:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	key chain name-of-chain	Identify a key chain, and enter key chain configuration
		mode.
Step 3
	key number	Identify the key number. The range is 0 to 2147483647.
Step 4
	key-string text	Identify the key string. The string can contain from 1 to
		80 uppercase and lowercase alphanumeric characters,
		but the first character cannot be a number.
Step 5 accept-lifetime start-time{infinite end-timeduration		(Optional) Specify the time period during which the key
	seconds}	can be received.
		The start-timeand end-timesyntax can be either
		hh:mm:ss Month date year or hh:mm:ss date Month
		year. The default is forever with the default start-time
		and the earliest acceptable date as January 1, 1993. The
		default end-timeand duration is infinite.
Step 6 send-lifetime start-time{infinite end-timeduration		(Optional) Specify the time period during which the key
	seconds}	can be sent.
		The start-timeand end-timesyntax can be either
		hh:mm:ss Month date year or hh:mm:ss date Month
		year. The default is forever with the default start-time
		and the earliest acceptable date as January 1, 1993. The
		default end-timeand duration is infinite.
Step 7
	end	Return to privileged EXEC mode.
Step 8
	show key chain	Display authentication key information.
Step 9
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

To remove the key chain, use the no key chain name-of-chainglobal configuration command.

Monitoring and Maintaining the IP Network

You can remove all contents of a particular cache, table, or database. You can also display specific statistics. Use the privileged EXEC commands in Table 38-15to clear routes or display status:

Table 38-15 Commands to Clear IP Routes or Display Route Status

show ip protocols		Display the parameters and state of the active routing protocol
		process.
