Configures ISAKMP proposals and their parameters
isakmp-proposal <WORD> encryption [3des|aes|aes-192|aes-256] group [14|2|5] hash [aes-xcbc-mac|md5|sha|sha256]
isakmp-proposal <WORD> encryption [3des|aes|aes-192|aes-256] group [14|2|5] hash [aes-xcbc-mac|md5|sha|sha256]
| <WORD> | Assigns the target peer (tunnel destination) a 32 character maximum name to distinguish it from others with a similar configuration. | 
| encryption [3des|aes|aes-192| aes-256] | Configures the
                        encryption method used by the tunneled peers to securely inter-operate 
 | 
| group [14|2|5] | Specifies the DH
                           (Diffie-Hellman) group identifier used by VPN peers to
                        derive a shared secret password without having to transmit. DH groups
                        determine the strength of the key used in key exchanges. The higher the
                        group number, the stronger and more secure the key. Options include 2, 5 and
                           14. 
 | 
| hash [maes-xcbc-mac| md5|sha|sha256] | Specifies the
                        hash algorithm used to authenticate data transmitted over the IKE SA. The
                        hash algorithm specified here is used by VPN peers to exchange credential
                           information.
