Default level
2: System level
Parameters
3des-cbc: Uses the 3DES algorithm in CBC mode as the encryption algorithm. The 3DES algorithm uses
168-bit keys for encryption.
aes-cbc: Uses the AES algorithm in CBC mode as the encryption algorithm. The AES algorithm uses
128-bit, 192-bit, or 256-bit keys for encryption.
key-length: Key length for the AES algorithm, which can be 128, 192 or 256 bits and is defaulted to 128
bits.
des-cbc: Uses the DES algorithm in CBC mode as the encryption algorithm. The DES algorithm uses
56-bit keys for encryption.
Description
Use the encryption-algorithm command to specify an encryption algorithm for an IKE proposal.
Use the undo encryption-algorithm command to restore the default.
By default, an IKE proposal uses the 56-bit DES encryption algorithm in CBC mode.
Related commands: ike proposal and display ike proposal.
Examples
# Use 56-bit DES in CBC mode as the encryption algorithm for IKE proposal 10.
