iting circuit parameters
To view and configure ATM PVC parameters:
- On the device view, highlight a port.
- Choose Edit > Port.
| The Port dialog box opens with the Interface tab displayed. |
- Click the ATM PVC tab.
| The table below describes the fields in the ATM PVC tab. |
|
Vpi
|
Virtual path identifier.
|
Vci
|
Virtual circuit identifier.
|
PvcId
|
Internal index ID of the PVC.
|
Name
|
Emulated LAN name.
|
Encapsulation
|
Encapsulation type: null or llcSnap.
|
ServiceType
|
Unspecified bit rate (ubr) or variable bit rate (vbr).
|
PeakCellRate
|
Peak cell rate, in cells/second, is the maximum cell rate.
Note: IP multicast traffic between a Passport module and other devices may not perform as well as expected unless the peak cell rate and the sustained cell rate values are updated to their maximum values; only applicable if the Service Type is vbr.
|
SustainedCellRate
|
Sustainable cell rate is an upper bound on the cell rate that is long relative to that of the PCR; only applicable if the Service Type is vbr.
|
MaxBurstSize
|
Maximum burst size determined by the signaling method; It is coded as a number of cells that can be transmitted at peak rate and still conform to the overall algorithm; only applicable if the Service Type is vbr.
|
- Click Insert.
| The Insert ATM PVC dialog box opens. |
| The table below describes the fields in the Insert ATM PVC dialog box. |
|
Vpi
|
Numeric value, within the range 0...255.
|
Vci
|
Numeric value, within the range 0...65535
Note: For <vpi.vci>, 0.0 is not supported.
|
Name
|
Alphanumeric characters to assign a name to the PVC.
|
Encapsulation
|
Encapsulation type: null or llcSnap.
|
ServiceType
|
Unspecified bit rate (ubr) or variable bit rate (vbr).
|
PeakCellRate
|
Numeric value, within the range 86...733490; only applicable if the Service Type is vbr.
|
SustainedCellRate
|
Numeric value, within the range 86...733490; only applicable if the Service Type is vbr.
|
MaxBurstSize
|
Numeric value, within the range 2...255; only applicable if the Service Type is vbr.
|
- In the Vpi field, type the VPI-bit size (an integer between 0 and 255).
- In the Vci field, type the VCI-bit size (an integer between 0 and 65, 535).
|
Note:
For <vpi.vci>, 0.0 is not supported.
|
- In the Name field, type the name of the ATM PVC.
- In the Encapsulation field, select the encapsulation method (null or IIcSnap).
- In the Service Type field, select the service type (ubr or vbr).
- If you select vbr in the Service Type field:
- In the PeakCellRate field, enter the PCR (an integer between 86 and 733490).
- In the SustainedCellRate field, enter the SCR (an integer between 86 and 733490).
- In the MaxBurstSize, type the maximum burst size (an integer between 2 and 255).
- Click Insert.
| The Insert ATM PVC dialog box closes. |
- Click Close.
