that accommodates it. (Refer to the x25 packet-size and x25 window-size
command for ways to set the flow control parameters of an X.25 interface.)
You can configure only one X.25 CLNS PVC for a point-to-multipoint X.25 interface.
So you must remove the existing one first if you want to configure another X.25 CLNS
PVC for the same interface.
Upon the establishment of a PVC, the corresponding address mapping is
automatically created. So to create the corresponding address mapping first is
unnecessary (and actually impossible).
Before create a PVC, be sure to enable the PVC channel range. The PVC channel
range refers to channels with channel numbers ranging from 1 (include) to the lower
limit (exclude) of the nearest channel range of enabled channels. If the lower limit
itself is 1, the PVC channel range is disabled.
Tab le 33 lists typical PVC channel ranges.
