Description
By default, no PVC is created. When creating such a PVC, if you do not set the
relevant attributes for the PVC, its flow control parameters will be the same as that
of the X.25 interface (the flow control parameters on an X.25 interface can be set
by the x25 packet-size and x25 window-size commands).
As one corresponding address mapping is created along with the PVC, it is
unnecessary (or impossible) to establish an address mapping first before creating
PVCs.
Before creating PVCs, you should first enable the PVC channel range. The range is
between 1 and the latest unprohibited channel PVC number minus 1 (including 1
and the lowest PVC number minus 1). Naturally, if the lowest PVC number is 1, the
PVC section will be disabled. The following table shows some typical PVC ranges.
