DESCRIPTION Use this command to (1) detect latency and congestion bottlenecks on F[L]_Ports and E_Ports and (2) to
manage credit recovery on backend ports. Bottleneck detection and credit recovery are two independent
functions; enabling credit recovery has no impact on bottleneck detection and vice versa.
Bottleneck Detection
For bottleneck detection, this command provides the following management functions:
• Enabling or disabling bottleneck detection on a switch and optionally configuring thresholds and alert
parameters.
• Changing alert parameters on specified ports after you have enabled the feature on the switch.
