Item Description
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. The valid
ranges are:
• OC-3—86..182783
• OC-12—86..733490
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.
The valid ranges are:
• OC-3—86..182783
• OC-12—86..733490
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.
