Min and Max are thresholds set on a per-queue, per-port basis and are measured in cells (53 bytes). The Min threshold is the amount of buffer space guaranteed to a call of a particular QoS on the corresponding port. The Max threshold is the maximum amount of buffer space that a call of a particular QoS is allowed on the corresponding port.

QoS corresponds to the queues as follows:

•Queue 1 — Constant Bit Rate (CBR)

•Queue 2 — Real Time Variable Bit Rate (rt-VBR)

•Queue 3 — Non-real time Variable Bit Rate (Nrt-VBR)

•Queue 4 — Unspecified Bit Rate (UBR)

If calls of a particular QoS type are being dropped on a particular port, use the set porttrafficcongestion command to raise the queue Min threshold.

For example, to change both the Min and Max amounts of buffer space used for CBR calls on port a3, enter the following:

SmartCell ZX # set porttrafficcongestion
Port(ALL)	: a3
Queue1MinimumCellCounter(20)	: 1000 < Min for CBR queue
