Juniper Apstra has indicated an anomaly with respect to cabling.

A cabling anomaly is an issue that occurs when the physical connections between the devices in the data center fabric do not match the expected connections based on the Apstra Reference Design. A cabling anomaly can cause problems such as incorrect routing, suboptimal traffic flow, or device isolation. To remediate the issue, you can use one or both of the following methods:

Manually edit the cabling map. This allows you to override the Apstra-generated cabling and specify the correct connections between the devices. You can use the Apstra UI or the Apstra CLI to edit the cabling map and apply the changes to the fabric12.

Have Apstra autoremediate the cabling map using LLDP. This allows Apstra to collect LLDP data from the devices and use it to update the cabling map automatically. LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors. Apstra can use the LLDP data to detect and correct any cabling errors in the fabric34. References:
