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:
•
•
•

Fabric OS Command Reference
53-1001764-01
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.
