DSL Commands
ATM Settings. You can use the CLI to set up each ATM vir tual circuit.
set atm option {on | off }
Enables the WAN inter face of the Motorola Netopia® Gateway to be configured using the Asynchronous
Transfer Mode (ATM) protocol.
set atm [vcc n ] option {on | off }
Selects the vir tual circuit for which fur ther parameters are set. Up to eight VCCs are suppor ted; the maxi-
mum number is dependent on your Motorola Netopia® Operating System tier and the capabilities that your
Ser vice Provider offers.
set atm [vcc n ] qos service-class { cbr | ubr | vbr }
Sets the Quality of Ser vice class for the specified vir tual circuit – Constant (cbr), Unspecified (ubr), or Vari-
able (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 ser-
vice 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 specifications
defined by your ser vice 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-rate that should apply to the specified virtual
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 sustained-cell-rate that should apply to the specified virtual cir-
cuit. This value should be less than, or equal to the Peak Cell Rate, which should be less than, or equal to
the line rate.
set atm [vcc n ] qos max-burst-size { 1 ... n }
If QoS class is set to vbr then specify the max-burst-size that should apply to the specified virtual circuit.
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.
