The severity of a high-bit error rate can vary and cause any of the following symptoms:

Failure to complete Auto-Negotiation when Auto-Negotiation is enabled.

Failure to obtain a link when Auto-Negotiation is disabled in both the core and the link partner.

High proportion of lost packets when passed between two connected devices that are capable of obtaining a link through Auto-Negotiation or otherwise. This can usually be accurately measured if the Ethernet MAC attached to the core contains statistic counters.

Note: All bit errors detected by the QSGMII Receive channel logic during frame reception show up as Frame Check Sequence Errors in an attached Ethernet MAC.
