DSL Commands

ATM Settings. You can use the CLI to set up each ATM virtual circuit.

set atm option {on off }

Enables the WAN interface of the Motorola Netopia® Gateway to be configured using the Asynchronous Transfer Mode (ATM) protocol.

set atm [vcc n] option {on off }

Selects the virtual circuit for which further parameters are set. Up to eight VCCs are supported; the

maximum number is dependent on your Motorola Netopia® Operating System tier and the capabilities that your Service Provider offers.

set atm [vcc n] qos service-class { cbr ubr vbr }

Sets the Quality of Service class for the specified virtual circuit – Constant (cbr), Unspecified (ubr), or Variable (vbr) Bit Rate.

❑ubr: No configuration is needed for UBR VCs. Leave the default value 0 (maximum line rate).

❑cbr: One parameter is required for CBR VCs. Enter the Peak Cell Rate that applies to the VC. This value should be between 1 and the line rate. You set this value according to specifications defined by your service provider.

❑vbr: Three parameters are required for VBR VCs. Enter the Peak Cell Rate, the Sustained Cell Rate, and the Maximum Burst Size that apply to the VC. You set these values according to specifi- cations defined by your service provider.

set atm [vcc n] qos peak-cell-rate { 1 ...n }

If QoS class is set to cbr or vbr then specify the peak-cell-ratethat should apply to the specified vir- tual circuit. This value should be between 1 and the line rate.

The Peak Cell Rate (PCR) should be set to the maximum rate a PVC can oversubscribe its Sustained Cell Rate (SCR). The Peak Cell Rate (see below) must be less than, or equal to the raw WAN (DSL) bit rate. The Maximum Burst Size (MBS) is the number of cells that can be sent at the PCR rate, after which the PVC must fall back to the SCR rate.

set atm [vcc n] qos sustained-cell-rate { 1 ...n }

If QoS class is set to vbr, then specify the tual circuit. This value should be less than, or equal to the line rate.

sustained-cell-ratethat should apply to the specified vir- or equal to the Peak Cell Rate, which should be less than,

set atm [vcc n] qos max-burst-size { 1 ...n }

If QoS class is set to vbr then specify the max-burst-sizethat should apply to the specified virtual cir- cuit. This value is the maximum number of cells that can be transmitted at the Peak Cell Rate after which the ATM VC transmission rate must drop to the Sustained Cell Rate.

set atm [vcc n] vpi { 0 ... 255 }

Select the virtual path identifier (vpi) for VCC n.
