Configure Port Threshold for a Site

Administrators can use the Port Threshold widget to define the traffic utilization thresholds for device ports. Utilization is the percentage of traffic the port carries relative to its operating capacity. The thresholds are set as percentage ranges and determine whether the port utilization is high, medium, or low.

The system uses these utilization ranges to classify port behavior in Per Port-Peak/ Off-Peak Traffic heatmap and to generate Low Traffic Port Optimization recommendations.

For port utilization description, see Table 1.

Table 1: Port Utilization Category
Utilization	Description
Low	The port is handling very little traffic relative to its capacity. Ports consistently falling in this range may be idle or underutilized ports and qualifies for optimization recommendations.
Medium	The port is carrying a moderate amount of traffic. Ports in this range are active but not operating in full capacity.
High	The port is carrying high volumes of traffic relative to its capacity. Ports in this range are heavily used and are not candidates for optimization recommendations.

The system provides default thresholds at the organization-level, inferred from historical traffic and usage patterns. These thresholds automatically apply to all sites unless they are customized at the site-level. Site-level configurations override the global thresholds.

Tip:

We recommend setting site-specific thresholds to reflect individual site's traffic patterns and operational behavior instead of using default values.

To configure port thresholds at the site-level:

Navigate to Organization > Site Configuration.
Click a site for which you want to set the port thresholds.

Locate the Port Threshold tile.

For widget element description, see Table 2.

Table 2: Widget Elements
Element	Description
Slider	Defines the boundaries between Low, Medium, and High utilization. If you do not configure port thresholds, default thresholds are applied for the ports.
Percentage markers	Indicate where each utilization range starts and ends on the 0–100% scale. Note: By default, the Low utilization range extends up to 25%, Medium up to 79%, and High up to 100% of the full port utilization scale.
Color bands on the slider	Visually represents each utilization range. The same colors appear in the site's Per Port Peak / Off-Peak Traffic Monitoring heatmap.
Color legend	Shows how Low, Medium, and High utilization levels are represented across Energy dashboards. Light Green—Low utilization Medium Green—Medium utilization Dark Green—High utilization

Adjust the slider to set the utilization thresholds.
The slider has two draggable handles.
- Left Handle—Drag the handle to control the boundary between Low and Medium utilization.
  
  Move this handle to the right to increase the Low utilization range (light green band expands).
  
  Move this handle to the left to increase the Medium utilization range (medium green band expands).
- Right Handle—Drag the handle to control the boundary between Medium and High utilization.
  
  Move this handle to the right to increase the Medium utilization range (medium green band expands).
  
  Move this handle to the left to increase the High utilization range (dark green band expands).
The slider displays the percentage at each handle position, indicating how much of the scale each utilization range occupies.

For example, if the left handle is set at 30% and the right handle at 70%, the system interprets the ranges as:
- Ports with traffic less than or equal to 30% are considered low utilization ports.
- Ports with traffic greater than 30% and up to 70% are considered medium utilization ports.
- Ports with traffic above 70% are considered as high utilization ports.
Click Save to apply the configuration.

Once applied, the dashboard updates the site's Per Port Peak / Off-Peak Traffic Monitoring heatmap to reflect utilization based on the configured thresholds.

Updating these thresholds may change how ports are classified and can result in updated Low Traffic Port Optimization recommendations, including changes to the time windows during which the recommendation is applicable.

Remember:
Update port thresholds as needed to reflect changes in site's traffic patterns or energy optimization goals.
