Step
4. Specify an ACL for the
IPsec policy.
5. Specify an IPsec
transform set for the IPsec
policy.
6. Specify the remote IP
address of the IPsec
tunnel.
7. Configure an SPI for the
inbound or outbound
IPsec SA.
8. Configure keys for the
IPsec SA.
Command
security acl [ ipv6 ] { acl-number |
name acl-name }
transform-set transform-set-name
remote-address { ipv4-address |
ipv6 ipv6-address }
•
To configure an SPI for the
inbound IPsec SA:
sa spi inbound { ah | esp }
spi-number
•
To configure an SPI for the
outbound IPsec SA:
sa spi outbound { ah | esp }
spi-number
•
Configure an authentication
key in hexadecimal format for
AH:
sa hex-key authentication
{ inbound | outbound } ah
{ cipher | simple } key-value
•
Configure an authentication
key in character format for AH:
sa string-key { inbound |
outbound } ah { cipher |
simple } key-value
•
Configure a key in character
format for ESP:
sa string-key { inbound |
outbound } esp { cipher |
simple } key-value
•
Configure an authentication
key in hexadecimal format for
ESP:
sa hex-key authentication
{ inbound | outbound } esp
{ cipher | simple } key-value
•
Configure an encryption key in
hexadecimal format for ESP:
sa hex-key encryption
{ inbound | outbound } esp
{ cipher | simple } key-value

Remarks
By default, an IPsec policy references no
ACL.
An IPsec policy can reference only one
ACL.
By default, an IPsec policy references no
IPsec transform set.
A manual IPsec policy can reference only
one IPsec transform set.
By default, the remote IP address of the
IPsec tunnel is not specified.
The local IPv4 address of the IPsec tunnel
is the primary IP address of the interface
to which the IPsec policy is applied. The
local IPv6 address of the IPsec tunnel is
the first IPv6 address of the interface to
which the IPsec policy is applied.
By default, no SPI is configured for the
inbound or outbound IPsec SA.
By default, no keys are configured for the
IPsec SA.
Configure keys correctly for the security
protocol (AH, ESP, or both) you have
specified in the IPsec transform set
referenced by the IPsec policy.
If you configure a key in both the
character and hexadecimal formats, only
the most recent configuration takes
effect.
If you configure a key in character format
for ESP, the device automatically
generates an authentication key and an
encryption key for ESP.
