Adjusts timeout durations and data retention periods to ensure reliable operation in large-scale topologies. It allows administrators to customize how the system handles slow responses and manages historical performance data, tailoring the controller's behavior to meet specific organizational requirements.

Configure TE timeout settings

If your setup includes many nodes, policies, or interfaces, a timeout may occur during policy deployment. To configure timeout settings for the provisioning and retrieval of data for SR-TE policies, RSVP-TE tunnels, Bandwidth on Demand and IGP paths, complete these steps:

Procedure

1.

Choose Administration > Settings > System settings > Traffic engineering > General settings.

2.

Enter the timeout duration options. For more information, click Field Help icon.

Note

Timeouts affect how quickly an action is completed if SR-PCE responds slowly. You can modify these settings for large-scale topologies or to address slow SR-PCE responses caused by latency or high load.

Path Analytics Resource Footprint To ensure optimal performance of Path Analytics, the following resources are required:

CPU/RAM: 2 vCPU, 6 GB RAM.

Storage: 1 GB PostgreSQL storage and 1 GB Filesystem storage.

Configure device group display for TE

You can configure how the topology map displays devices when a device group is selected. If a device that is part of an SR policy, service, or RSVP-TE tunnel does not belong to the selected group, its status can be shown separately.

To adjust this setting, choose Administration > Settings > User settings > Switch device group and select one of the behavior options.

By default, the user is asked to choose the device group view each time.

Configure TE data retention settings

To view LSP utilization history in the Historical tab, LSP utilization collection must be enabled and the retention period for collected data must be specified.

To configure TE data retention settings, complete these steps:

Procedure

1.

Choose Administration > Settings > System settings > Data retention > Network performance.

2.

In the Collect metrics data section, select the items (LSP utilization, LSP PM, and Link PM) for which you would like metrics to be collected and retained.
3.

Optionally, edit the default data retention periods according to your organization requirements.

Note
If you reduce the retention period, all data older than the new period is deleted. For example, if the daily retention interval is set to 7 days and then reduced to 24 hours, all data older than 24 hours is deleted.
