Cajun A500 ATM Switch User Guide

The 

modify add_channel point-point

 command creates a point-to-point virtual 

channel between two ATM ports on an Cajun A500. You must create a circuit if you 

want to statically wire any connections in the switch module of the Cajun A500. 

modify add_channel point-point { input_port } { input_vpi } { input_vci 

} 

{ output_port } { output_vpi } { output_vci } { class } { incellrate | 

ppd }  {outcellrate}

This command requires the following argument(s):

input_port

Specify the port number where the VCI enters. Valid values are A1.1 - A4.8 

and “self” for a connection that terminates in the Cajun A500.

input_vpi

Specify the incoming Virtual Path Identifier number. Valid range is 0 - 255.

input_vci

Specify the incoming Virtual Channel Identifier (VCI) number. Valid range 

is 32 - 2015.

output_port

Specify the port 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 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.

outcellrate

The outcellrate is based on the service class you select. 

• For CBR, specify the peak cell rate in the direction from the output port 

to the input port. 

• For VBR specify the peak cell rate, sustained cell rate, and maximum 

burst size in the direction from the output port to the input port.
