TO CONFIGURE AUTHENTICATION TYPE
EXAMPLE
ALU(config-crypto-ike-policy-P1)# authentication pre-shared
Note: If the Authentication type is not explicitly configured, default pre-shared is used.
TO CONFIGURE TRANSFORM-SET IN IPSEC
A transform set represents a certain combination of security protocols and 
algorithms. During the IPsec security association negotiation, the peers agree to 
use a particular transform set for protecting a particular data flow.
Note:  You can specify a maximum of 4 values in  a  t r a n s f orm se t .          
Note: The “force“ keyword is used to modify or edit the transform-set in use.
Options for proposal under transform-set:
• esp-md5-3des       encapsulation with MD5 and 3DES encryption
• esp-md5-aes128   encapsulation with MD5 and 128 bit AES encryption
• esp-md5-aes192   encapsulation with MD5 and 192 bit AES encryption
• esp-md5-aes256   encapsulation with MD5 and 256 bit AES encryption
• esp-md5-des        encapsulation with MD5 and 56 bit DES encryption
• esp-sha1-3des      encapsulation with SHA1 and 3DES encryption
• esp-sha1-aes128   encapsulation with SHA1 and 128 bit AES encryption
• esp-sha1-aes192   encapsulation with SHA1 and 192 bit AES encryption
• esp-sha1-aes256   encapsulation with SHA1 and 256 bit AES encryption
• esp-sha1-des        encapsulation with SHA1 and 56 bit DES encryption
Command (in IKE Policy CM) Description
authentication {pre-shared|rsa-sig} This command configures the 
authentication type to be used 
during IKE negotiation.
Command (in CM) Description
crypto ipsec transform-set <name> 
{<algo>[<algo>][<algo>] [<algo>]} 
[force]
This command creates a 
transform-set.
