Parameter description in the page:
Set an exchange mode negotiated in Stage 1. This exchange mode must be the same as that
of the remote end.
There are two exchange modes as follows:
MAIN: This mode allows both parties to exchange many packets, provides identity
protection, and applies to situations with high requirements for identity protection.
AGGRESSIVE: Also called ACTIVE. This mode provides no identity protection, allows
parties to exchange a small number of packets, has a fast negotiation speed, and applies
to situations with low requirements for identity protection.
Select an encryption algorithm applied to an IKE session.
The router supports the following encryption algorithms:
DES (Data Encryption Standard): Encrypt64-bit data using a 56-bit key. The last 8 bits of
64 bits are used for parity check. 3DES (Triple DES) performs encryption using three
56-bit keys.
AES (Advanced Encryption Standard): AES128/192/256 indicates performing encryption
