Examples
The following example enables bottleneck detection on the switch with alerts
using default values for thresholds and time, and is the recommended manner of
enabling bottleneck detection
switch:admin> bottleneckmon --enable -alert
The following example enables bottleneck detection on the switch without alerts.
In this case, even though alerts are not delivered, you can still view the
bottleneck history using either the CLI or BNA.
switch:admin> bottleneckmon --enable
Displaying bottleneck detection configuration details
To display the bottleneck detection configuration details, complete the following steps.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter bottleneckmon --status to display the details of bottleneck detection configuration for the
switch, which includes the following details:
• Whether the feature is enabled
• Switch-wide parameters
• Per-port overrides, if any
• Excluded ports
The following initials in the "Per-port overrides for alert parameters," section of the output indicate
which alerts have been set:
• C indicates a congestion alert has been set.
• L indicates a latency alert has been set.
• Y indicates both alerts are set.
• N indicates no alerts are set.
The following examples show the status of different bottleneck alerts.
This example shows that bottleneck detection is not enabled:
switch:admin> bottleneckmon --status
Bottleneck detection - Disabled
This example shows that congestion and latency alerts are enabled:
switch:admin> bottleneckmon --status
Bottleneck detection - Enabled
