Ike Invalid-Spi-Recovery Enable - HP 6125XLG Command Reference Manual

user-fqdn user-fqdn-name : Uses the user FQDN name as the identity. The user-fqdn-name argument is a
case-sensitive string of 1 to 255 characters, for example, abc@test.com. If you do not specify this
argument, the device name configured by using the sysname command is used as the user FQDN.
Usage guidelines
The global identity can be used by the device for all IKE SA negotiations, and the local identity (set by
the local-identity command) can be used only by the device that uses the IKE profile.
In pre-shared key authentication, you cannot set the DN as the identity.
In signature authentication:
You can set any type of the identity information.
•
The ike signature-identity from-certificate command sets the local device to always use the identity
•
information obtained from the local certificate.
If the ike signature-identity from-certificate command is not set, the local-identity command
•
configuration, if configured, takes precedence over the ike identity command configuration.
Examples
# Set the IP address 2.2.2.2 as the identity.
<sysname> system-view
[sysname] ike identity address 2.2.2.2

Usage guidelines
IPsec "black hole" occurs when one IPsec peer fails (for example, a peer can fail if a reboot occurs). One
peer fails and loses its SAs with the other peer. When an IPsec peer receives a data packet for which it
cannot find an SA, an invalid SPI is encountered. The peer drops the data packet and tries to send an SPI
invalid notification to the data originator. This notification is sent by using the IKE SA. When no IKE SA
is available, the notification is not sent. The originating peer continues sending the data by using the
IPsec SA that has the invalid SPI, and the receiving peer keeps dropping the traffic.
