412 CHAPTER 23: IKE CONFIGURATION COMMANDS
encryption-algorithm Syntax
encryption-algorithm { des-cbc | 3des-cbc }
undo encryption-algorithm
View
IKE proposal view
Parameter
des-cbc: Selects the 56-bit DES-CBC encryption algorithm for an IKE proposal.
DES algorithm adopts 56-bit keys for encryption.
3des-cbc: Sets the encryption algorithm to the 3DES algorithm in CBC mode. The
3DES algorithm uses 168-bit keys for encryption.
Description
Use the encryption command to specify the encryption algorithm for an IKE
proposal.
Use the undo encryption command to restore to the default.
By default, 56-bit DES-CBC encryption algorithm is used.
Related command: ike proposal and display ike proposal.
Example
# Specify the 56-bit DES-CBC encryption algorithm for IKE proposal 10.
[SecBlade_VPN] ike proposal 10
[SecBlade_VPN-ike-proposal-10] encryption-algorithm des-cbc
exchange-mode Syntax
exchange-mode { aggressive | main }
undo exchange-mode
View
IKE-peer view
Parameter
aggressive: Aggressive mode
main: Main mode.
Description
Use the exchange-mode command to select an IKE negotiation mode.
Use the undo exchange-mode command to restore the default negotiation
mode. By default, main mode is adopted.
