Display the Class of Service Buffer parameters for SCT 3 Note the following:
• Min-Rate and Max-Rate do not apply in the current product.
• Excess-Priority is a scheme for distributing excess bandwidth. The lowest number is the highest
priority for a connection to receive excess bandwidth. If two or more connections have equal
priority, the excess bandwidth is equally distributed between them.
• Explicit Rate Stamping (ERS) applies to only ABR connections.
• Cell loss ratio (CLR) is currently hard-coded, so do not attempt to modify it through CWM.

Display VC thresholds for SCT 3. Note the following:
The Scaling COSB value applies to congestion in a Class of Service Buffer: if a buffer becomes
congested, this value determines how quickly the node throttles back the rate that cells enter the buffer.
The Scaling Log-If is a scaling factor that applies to congestion on a port: when the port is congested,
this factor determines the rate at which traffic is throttled back.
