encryption-algorithm { none | { aes-128 | des | 3des }* }

VPN domain view

none: Specifies not to encrypt control packets.

aes-128: Specifies to adopt AES encryption algorithm, with the key length being 
128 bits.

des: Specifies to adopt DES encryption algorithm.

3des: Specifies to adopt 3DES encryption algorithm.

Use the encryption-algorithm command to configure the encryption and its 
corresponding priority for protocol packets.

Use the undo encryption-algorithm command to restore the default.

By default, AES-128, 3DES and DES are adopted, with their priorities from the 
highest to the lowest being AES-128, 3DES, and DES.

Note that:

■

Priorities of encryption algorithms are decided by their configuration order.

■

Based on its encryption algorithm configuration, a VAM server negotiates with 
a client to determine the encryption algorithm to be used between them.

# Specifies to adopt AES-128 and 3DES encryption algorithms in VPN domain 1, 
with the priority of AES-128 higher than that of 3DES.
