# Other Counters

This section displays the data shown in the following table. Refer to Appendix A Port Counters Overview for more information.

Other Counters
Data Displayed | Description
--- | ---
LocalLinkIntegrityErrors | This counter indicates the number of retries initiated by the link transfer layer. It may be indicative of low signal quality, or may be due to long or low quality cables.
FMConfigErrors | This counter indicates inconsistencies of low level SMA configuration on both sides of the link. It is indicative of the possible misconfiguration of a port, either by the SM, or (more likely) by user intervention (by using a tool such as `opaportconfig`).
ExcessiveBufferOverruns | This counter, associated with credit management, indicates an input buffer overrun. It may indicate possible misconfiguration of a port, either by the SM or (more likely) by user intervention (e.g. using a tool such as `opaportconfig`).
SwPortCongestion | This switch-only counter indicates the number of packets that were discarded as unable to transmit due to flow control issues.
MarkFECN | This counter indicates the total number of packets that were marked FECN by the transmitter due to congestion.
LinkErrorRecovery | This counter indicates the number of times the link has successfully completed the link error recovery process. If LQI is fluctuating toward low values AND this counter is increasing, it may be indicative of a bad link. Indication of a more severe signal quality problem.
LinkDowned | This counter indicates the total number of times the port has failed the link error recovery process and downed the link. A large number of occurrences of these events can cause disruptions to fabric traffic.
UncorrectableErrors | This counter indicates the number of unrecoverable internal device errors. It is indicative of a severe hardware defect or data corruption on the wire.
LinkQualityIndicator | This is a status indicator, similar to the signal strength bar display on a mobile phone, that enumerates link quality as a range of 0-5, with 5 being very good. Values in the lower part of the range may indicate hardware problems such as port, cable, etc. that surface as signal integrity issues, leading to performance and other problems.
