+.Sh DESCRIPTION
+.Nm
+displays or controls the shaper parameters of an ATM VC.
+When a shaper value is specified,
+.Nm
+sets a shaper to an ATM VC.
+.Nm
+works for a PVC sub interface
+.Xr pvc 4
+as well as a real ATM interface
+.Xr en 4 .
+.Pp
+For a real ATM interface, the specified VC should be assigned
+beforehand by
+.Xr route 8 .
+.Pp
+For a sub interface,
+.Nm
+assigns the specified VC to the sub interface. If another VC is
+already assigned to the sub interface, the old VC is invalidated.
+.Pp
+Availability of shapers, the number of hardware shaper channels,
+and accuracy of shaping are all device dependent.
+For example, ENI Midway chip has 8 shaper channels but the driver
+reserves one for non-shaping VCs.
+.Pp
+The options are as follows:
+.Bl -tag -width Fl
+.It Ar Interface
+The
+.Ar inerface
+parameter is a string of the form
+.Dq name unit ,
+for example,
+.Dq en0
+.It Op vpi: Ar vci
+The VC number to which the shaper is assigned.
+When the VPI number is omitted, VPI number 0 is
+assumed.
+For example, to assign a shaper to VPI=0 and
+VCI=201, the following forms can be used:
+"201", "0xc9", "0:201", "0:0xc9".
+.It Fl p Ar pcr
+The PCR (Peak Cell Rate) parameter specifies the peak cell rate in
+"cells per second".
+If PCR value "0" is specified,
+no shaper is assigned, which means cells are sent at
+full-speed of the link.
+If PCR value
+.Dq -1
+is specified, the corresponding VC
+is invalidated.
+.It Fl b Ar max-bandwidth
+The PCR parameter can be specified also in
+.Dq bits per second .
+The rate is the rate of AAL5 frame and
+the PCR is calculated by the following form:
+.Pp
+.Dl PCR = max-bandwidth / 8 / 48
+.Pp
+.Dq K
+and
+.Dq M
+can be used as a short hand of
+.Dq 000
+and
+.Dq 000000
+respectively. For example,
+.Dq 45M
+means
+.Dq 45Mbps
+or PCR value
+.Dq 117187 .
+.It [-j [vpi:]vci]
+The join parameter is intended for VP shaping.
+The VC shaper channel is shared with the existing VC,
+which means the sum of the cell rates never exceeds
+the maximum PCR among the shared VCs.
+On the other hand, when the shaper channel is not shared,
+the sum of the cell rates could be the sum of the PCRs.
+.Pp
+For example, if two VCs (say 201 and 202) share a
+45Mbps VP, use:
+.Pp
+.Dl # pvctxctl en0 201 -b 45M
+.Dl # pvctxctl en0 202 -b 45M -j 201
+.It Fl n
+This parameter is only for a sub interface.
+Use NULL encapsulation instead of LLC/SNAP.
+.El
+.Sh CAVEATS
+A real ATM interface and a sub interface require different
+sequences to set a shaper.
+For example, to assign a 45Mbps shaper to VC 201 (0xc9) of en0:
+.Pp
+.Dl # ifconfig en0 10.0.0.1
+.Dl # route add -iface 10.0.0.2 -link en0:3.0.0.c9
+.Dl # pvctxctl en0 0xc9 -b 45M
+.Pp
+For a shadow interface,
+.Pp
+.Dl # pvcsif en0 # creates pvc0
+.Dl # ifconfig pvc0 10.0.0.1 10.0.0.2
+.Dl # pvctxctl pvc0 201 -b 45M
+
