Traffic Management

SmartCell 6A000 user data cells are classified according to the state of a cell loss priority (CLP) bit in the header of each cell. A CLP 1 cell has a lower priority than a CLP 0 cell, and is discarded first. Source traffic descriptors can specify CLP 0 cell traffic, CLP 1 cell traffic, or the aggregate CLP 0+1 traffic.

Use the trafficdescriptor commands to view, create, and delete traffic descriptors.

For example, enter the show trafficdescriptor command to view all currently defined traffic descriptors.

The Descriptor Type parameter in the example above corresponds to the traffic descriptor types defined in the UNI3.0/UNI3.1specification. Descriptor types are specified numerically and are as follows:

1 = No Traffic Descriptor

2 = Traffic Descriptor with no CLP and no SCR

3 = Traffic Descriptor with CLP, no Tagging, and no SCR

4 = Traffic Descriptor with CLP, Tagging, and no SCR

5 = Traffic Descriptor with no CLP and SCR

6 = Traffic Descriptor with CLP, no Tagging, and SCR

7 = Traffic Descriptor with CLP, Tagging, and SCR

8 = Traffic Descriptor with CLP and best effort

PVCs can use user-defined traffic descriptors. For instance, if a video link over a PVC requires a constant data flow of 5000 kb/s and a peak cell rate of 8000 kb/s, create a traffic descriptor for CBR traffic that specifies 5000 as the sustained cell rate and 8000 as the peak cell rate.
