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 back-end 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.
• Configuring severity thresholds for congestion and latency bottlenecks for a switch or for a specified
port list.
• Refining the criterion for defining latency bottleneck conditions to allow for more (or less) sensitive
monitoring at the sub-second level.
• Clearing the configuration on specified ports only (this option cannot be performed switch-wide).
• Excluding specified ports from being monitored or including previously excluded ports.
• Generating history or status reports that show congestion bottlenecks and latency bottlenecks.
