SA parameters of IKE negotiated IPSec policies are subject to IKE, which is also

responsible for establishing SAs.
When configuring an IPSec policy, you need to set the parameters of both the
■
inbound and outbound SAs.
The SPI for the inbound SA at the local end must be the same as that for the
■
outbound SA at the remote end, and the SPI for the outbound SA at the local
end must be the same as that for the inbound SA at the remote end.

inbound: Specifies the inbound SA through which. IPSec processes the received
packets.
outbound: Specifies the outbound SA through which IPSec processes the packets
to be sent.
ah: Uses AH.
esp: Uses ESP.
string-key: Key string for the SA, consisting of 1 to 255 characters. For different
algorithms, you can input strings at any length in the specified range. Using this
