2.4.  Management Considerations

   This section provides several network management guidelines for
   implementations supporting the credit window flow control mechanisms
   defined in this document.

   Modems MAY support the configuration of the number of credit windows
   (queues) to advertise to a router.

   Routers may have limits on the number of queues that they can
   support.  They may even have limits on supported credit window
   combinations.  For example, per-destination queues may not be
   supported at all.  When credit window information provided by a modem
   exceeds the capabilities of a router, the router SHOULD use a subset
   of the provided credit windows.  Alternatively, a router MAY reset
   the session and indicate that the extension is not supported.  In
   either case, any mismatch in capabilities SHOULD be reported to the
   user via normal network management mechanisms, such as the user
   interface or error logging.

   In all cases, if credit windows are in use, traffic for which credits
   are not available MUST NOT be sent to the modem by the router.
