Usage guidelines
After the ipffmagicnumber update command is enabled, the device decides whether a service can be
fast forwarded according to the driver registration. If the service can be fast forwarded, the device issues
the session for the service to the driver. Then the driver creates or updates a fast forwarding entry as
follows:
• If no fast forwarding entry exists, the driver creates a new entry.
• If a fast forwarding entry exists, and the magic numbers do not change, the driver does not need to
update the forwarding entry.
