undo encrypt-card fast-switch

Parameter
None
Description
Use the encrypt-card fast-switch command to enable the fast forwarding function of
the encryption card.
Use the undo encrypt-card fast-switch command to disable the fast forwarding
function of the encryption card.
By default, the fast forwarding function of the encryption card is disabled.
For the packets that have the same [SourIP, SourPort, DestIP, DestPort, Prot] quintuple,
the router creates a fast forwarding entry when it receives the first packet. Then, the
subsequent packets, rather than processed packet by packet, are sent directly to the
encryption card, where they are sent to the destination after being encrypted or
decrypted. This is how the fast forwarding function of the encryption card expedites
packet processing.
Example
# Enable the fast forwarding function of the encryption card.
