Description (partial)

When an interface goes down on a managed network switch or router, Assurance in the Cisco DNA Center will display an issue notifying consumers that the interface is no longer up. One of the suggested remediations is to run the TDR cable diagnostics for troubleshooting. On certain interfaces, this command may not be applicable.

The interface that has gone down is of a speed not supported by TDR cable diagnostics (only 10G and below are supported).
