566 CHAPTER 40: CONFIGURING IPSEC
Table 634 Enable/Disable the Host to Backup the NDEC Cards
By default, the host is disabled to backup the crypto cards.
Defining IPSec Proposal The IPSec saved in conversion mode needs a special security protocol and
encryption/authentication algorithm to provide various security parameters for the
IPSec negotiation security confederation. Both ends must use the same conversion
mode for successfully negotiating IPSec security confederation.
Define IPSec proposal
Multiple IPSec proposals can be defined, and then one or many of them can be
quoted in one security policy. The same security protocol and algorithm conversion
must be configured at both ends when security confederation is manually created.
If you modify the conversion mode after successful security confederation
negotiation, this security confederation will still use the former conversion mode,
while the newly negotiated security confederation will use the new conversion
mode. To make the new setting effective at once, it is necessary to use the
reset
ipsec sa
command to clear part or all of the SA database.
Perform the following configurations in system view.
Table 635 Define IPSec Proposal
By default, no proposal view is configured.
Set the Mode for Security Protocol to Encapsulate IP Message
The IP message encapsulating mode selected by both ends of security tunnel must
be consistent.
Configure the following in IPSec proposal view (or proposal view of crypto card).
