2160 CHAPTER 141: IKE CONFIGURATION COMMANDS

dpd

Syntax	dpd dpd-name
	undo dpd
View	IKE Peer view
Parameter	dpd-name: DPD name, a string of 1 to 15 characters.
Description	Use the dpd command to apply a DPD to an IKE peer.
	Use the undo dpd command to remove the application.
	By default, no DPD is applied to an IKE peer.
Example	# Apply DPD dpd1 to IKE peer peer1.
	<Sysname> system-view
	[Sysname] ike peer peer1
	[Sysname-ike-peer-peer1] dpd dpd1

encryption-algorithm

Syntax	encryption-algorithm { 3des-cbc aes-cbc [ key-length] des-cbc }
	undo encryption-algorithm
View	IKE proposal view
Parameter	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-algorithmcommand to specify the encryption algorithm
	for an IKE proposal.
	Use the undo encryption-algorithmcommand to restore the default.
	By default, an IKE proposal uses the 56-bit DES encryption algorithm in CBC
	mode.
