Assign colours to link health thresholds

Learn how to assign colour thresholds for link health metrics on topology maps, enabling visual categorization of network links based on metrics such as delay, jitter, packet errors, packet drops and loss.


Before you begin

  • Verify that Segment Routing Performance Monitoring (SR-PM) is enabled if you want to use delay and jitter metrics. Enabling SR-PM requires installation of Service Health, available as part of the Crosswork Network Controller Advantage package.

  • Refer to the Enable SR-PM monitoring for links and TE policies section in the Cisco Crosswork Network Controller Service Health Monitoring guide for detailed steps.

Procedure

1.

From the main menu, choose Administration > Settings > System Settings.

2.

Under Topology, select Metric thresholds.

3.

Define the colour criteria for links. Each row defines a color and the percentage range that the color will represent.

  • For each row, specify a colour and the percentage range it represents.

  • Enter values in the To fields only, each row starts from the end of the previous row's range.

  • Ensure that ranges are sequential, with no overlaps. For example, after a 0-25% range, the next row must begin above 25%.

  • Assign a unique colour to each threshold. Do not reuse colours for multiple ranges.

  • Colour-coded link thresholds apply to metrics such as bandwidth utilization, delay, jitter, packet errors, and packet drops.

  • Delay and jitter metrics are only available when SR-PM is enabled.
