H3C S6550X-HI Series Command Reference Manual page 2287

Use
undo sa string-key
Syntax
sa string-key { inbound | outbound } { ah | esp } [ cipher | simple ] string
undo sa string-key { inbound | outbound } { ah | esp }
Default
No key string is configured for manual IPsec SAs.
Views
IPsec policy view
IPsec profile view
Predefined user roles
network-admin
Parameters
: Sets a key string for inbound IPsec SAs.
inbound
: Sets a key string for outbound IPsec SAs.
outbound
: Uses AH.
ah
: Uses ESP.
esp
: Specifies a key string in encrypted form.
cipher
: Specifies a key string in plaintext form. For security purposes, the key string specified in
simple
plaintext form will be stored in encrypted form.
: Specifies the key string. Its encrypted form is a case-sensitive string of 1 to 373 characters.
string
Its plaintext form is a case-sensitive string of 1 to 255 characters. Using the key string, the system
automatically generates keys that meet the algorithm requirements. When the protocol is ESP, the
system automatically generates keys for the authentication algorithm and encryption algorithm.
Usage guidelines
This command applies only to manual IPsec policies and IPsec profiles.
You must set a key for both inbound and outbound SAs.
The local inbound SA must use the same key as the remote outbound SA, and the local outbound SA
must use the same key as the remote inbound SA.
The keys for the IPsec SAs at the two tunnel ends must be input in the same format (either in
hexadecimal or character format). Otherwise, they cannot establish an IPsec tunnel.
When you configure an IPsec profile for an IPv6 routing protocol, follow these guidelines:
•
The local inbound and outbound SAs must use the same key.
•
The IPsec SAs on the devices in the same scope must have the same key. The scope is defined
by protocols. For OSPFv3, the scope consists of OSPFv3 neighbors or an OSPFv3 area. For
RIPng, the scope consists of directly-connected neighbors or a RIPng process. For BGP, the
scope consists of BGP peers or a BGP peer group.
If you execute this command multiple times, the most recent configuration takes effect.
Examples
# Configure the inbound and outbound SAs that use AH to use plaintext keys abcdef and efcdab,
respectively.
