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.
aes-cbc [ 128 | 192 | 256 ]: Sets the encryption algorithm to AES in CBC mode. 128 bits,
192 bits, and 256 bits are available key lengths. The default is 128 bits.
Description
Use the encryption-algorithm command to specify the encryption algorithm for an IKE
proposal.
Use the undo encryption-algorithm 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.
