Syntax

undo ipsec invalid-spi-recovery enable
Default
The invalid SPI recovery is disabled. The receiver discards IPsec packets with invalid SPIs.
Views
System view
Default command level
2: System level
Usage guidelines
Invalid SPI recovery enables an IPsec security gateway to send an INVALID SPI NOTIFY message to its
peer when it receives an IPsec packet but cannot find any SA with the specified SPI. When the peer
receives the message, it deletes the SAs on its side. Then, subsequent traffic triggers the two peers to
establish new SAs.
Examples
# Enable invalid SPI recovery.
<Sysname> system-view
[Sysname] ipsec invalid-spi-recovery enable
ipsec policy (interface view)
Use ipsec policy to apply an IPsec policy group to an interface.
Use undo ipsec policy to remove the application.
Syntax
ipsec policy policy-name
undo ipsec policy [ policy-name ]
Views
Interface view
Default command level
2: System level
Parameters
policy-name: Specifies the name of the existing IPsec policy group to be applied to the interface, a string
of 1 to 15 characters.
Usage guidelines
Only one IPsec policy group can be applied to an interface. To apply another IPsec policy group to the
interface, remove the original application first. An IPsec policy group can be applied to more than one
interface.
With an IPsec policy group applied to an interface, the system uses each IPsec policy in the group to
protect certain data flows.
