Parameters
inbound: Specifies an SPI for inbound SAs.
outbound: Specifies an SPI for outbound SAs.
ah: Uses AH.
esp: Uses ESP.
spi-number: Specifies a Security parameters index (SPI), in the range of 256 to 4294967295.
Usage guidelines
This command applies to only manual IPsec policies and IPsec profiles.
You must configure an SPI for both inbound and outbound SAs, and make sure the SAs in each direction
are unique: For an outbound SA, make sure its triplet (remote IP address, security protocol, and SPI) is
unique. For an inbound SA, make sure its SPI is unique.
The local inbound SA must use the same SPI as the remote outbound SA, and the local outbound SA must
use the same SPI as the remote inbound SA.
Examples
# Set the SPI for the inbound SA to 10000 and the SPI for the outbound SA to 20000 in a manual IPsec
policy.
