VPN Acceleration Module 2+ (VAM2+) Installation and Configuration Guide

OL-5979-03

Chapter 4      Configuring the SA-VAM2+

  Configuration Tasks

Another transform set example is “myset2,” which uses Triple DES encryptions and MD5 (HMAC 
variant) for data packet authentication: 

crypto ipsec transform-set myset2 esp-3des esp-md5-hmac

A crypto map joins together the IPSec access list and transform set and specifies where the protected 
traffic is sent (the remote IPSec peer):

crypto map toRemoteSite 10 ipsec-isakmp

match address 101

set transform-set myset2

set peer 10.2.2.5

The crypto map is applied to an interface:

interface Serial0

ip address 10.0.0.2

crypto map toRemoteSite

Note

In this example, IKE must be enabled.

Verifying IKE and IPSec Configurations

To view information about your IPSec configurations, use 

show crypto ipsec transform-set

 EXEC 

command.

Note

If a user enters an IPSec transform that the hardware (the IPSec peer) does not support, a warning 
message will be displayed in the 

show crypto ipsec transform-set 

output.

The following sample output from the 

show crypto ipsec transform-set 

command displays a warning 

message after a user tries to configure an IPSec transform that the hardware does not support: 

Router#

show crypto ipsec transform-set

Transform set transform-1:{esp-256-aes esp-md5-hmac}

   will negotiate = {Tunnel, },

WARNING:encryption hardware does not support transform

esp-aes 256 within IPSec transform transform-1

To view information about your IKE configurations, use 

show crypto isakmp policy 

EXEC command.

Note

If a user enters an IKE encryption method that the hardware does not support, a warning message will 
be displayed in the 

show crypto isakmp policy 

output.

The following sample output from the 

show crypto isakmp policy 

command displays a warning 

message after a user tries to configure an IKE encryption method that the hardware does not support: 

Router#

show crypto isakmp policy

Protection suite of priority 1

        encryption algorithm:  AES - Advanced Encryption Standard (256 bit keys).

WARNING:encryption hardware does not support the configured

encryption method for ISAKMP policy 1

        hash algorithm:        Secure Hash Standard

        authentication method: Pre-Shared Key
