Cisco Systems 7401ASR manual Using the Exec Command Interpreter, Configuring IKE

Chapter 4 Configuring the VPN Acceleration Module

Configuration Tasks

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed. When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#

This completes the procedure for entering the privileged level of the EXEC command interpreter.

Configuring IKE

If you do not specify a value for a parameter, the default value is assigned. For information on default values, refer to the “IP Security and Encryption” chapter of the Security Command Reference publication.

To configure a policy, use the following commands, starting in global configuration mode:

	Command	Purpose
Step 1	crypto isakmp policy priority	Identifies the policy to create, and enters config-isakmp
		command mode.
Step 2	encryption {des 3des}	Specifies the encryption algorithm.
Step 3	group {1 2}	Specifies the Diffie-Hellman group identifier.

For detailed information on creating IKE policies, refer to the “Configuring Internet Key Exchange Security Protocol” chapter in the Security Configuration Guide publication.
