Cajun A500 ATM Switch User Guide
modify add_channel multipoint
Purpose
The
modify add_channel multipoint
command creates a point-to-multipoint virtual
channel between two ATM ports on an Cajun A500. You must create a circuit to
statically wire any connections in the switch module of the Cajun A500. Use the
modify
add_channel multipoint
command when setting up the initial connection or adding a
leaf to an existing circuit. All point-to-multipoint connections require a priority of four.
Syntax
modify add_channel multipoint <input_port> <input_vpi> <input_vci>
<output_port> <output_vpi> <output_vci> {class} {incellrate | ppd}
Arguments
This command requires the following argument(s):
Note: Partial Packet Discard can only be used for connections using AAL5.
input_port
Specify the port number where the VCI enters. Valid values are A1.1 through
A4.8 and self for a connection that terminates in the Cajun A500.
input_vpi
Specify the incoming Virtual Path Identifier (VPI) number. Valid range is 0 - 255.
input_vci
Specify the incoming Virtual Channel Identifier (VCI) number. The valid range is
32 - 2015.
output_port
Specify the port number where the VCI exits. Valid values are A1.1 - A4.8.
output_vpi
Specify the outgoing VPI number. The valid range is 0 - 255.
output_vci
Specify the outgoing VCI number. Valid range is 32 - 2015.
class
Specify the Quality of Service (QoS) class. Valid values are: CBR, VBR, or UBR.
incellrate | ppd
The incellrate and ppd are based on the service class you select.
For CBR, specify the peak cell rate in the direction from the input port to the
output port.
For VBR, specify the peak cell rate, sustained cell rate, and maximum burst
size in the direction from the input port to the output port.
For UBR, specify whether you want Partial Packet Discard (PPD) turned on or
off for the connection.
