Configuring the IPsec Backward Checking Function

Configuring the IPsec Backward Checking Function

Configuring the IPSec backward checking function ensures that the data flow is correctly encrypted.

Context

Configuring the IPSec backward checking function ensures that the data flow is correctly encrypted. When the IPSec backward checking function is enabled, the NE20E checks the packets received by the interface.

  • Packet in encrypted text (IPSec succeed-check function)

    The NE20E checks the decrypted packet that is in plain text and discards the encrypted packet if it is supposed to be unencrypted.

For the IPSec deployment using the IPSec policy template, the IPSec backward check function only checks the data flow that matches the ACL rule referred to by the IPSec policy template with the smallest number.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run ipsec succeed-check enable

    The IPsec succeed-check function is enabled.

  3. Run commit

    The configuration is committed.
