Cisco Nexus: Ethernet FCS errors Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoNexus.EthernetFCSErrors.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Ethernet FCS errors if has changed its state.

Knowledge Base article:

Summary

Number of ethernet FCS errors is over threshold.

The number of frames that do not pass the FCS check is above the maximum threshold configured in Xian Network Manager.

Causes

A frame is considered by this rule when the FrameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions obtained are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.

Station powering up or down, faulty cabling, network noise, faulty transceiver, fault at the transmitting end station, or faulty adapter.

Resolutions

When an error is caused by in-bound noise due to powering up, no action is required. Otherwise: examine the cable and cable connections for breaks or damage; look for improper cabling, faulty cables, faulty network equipment, and cables that are too close to equipment that emits electromagnetic interference; use an analyzer to identify the problematic transceiver and if necessary, replace the transceiver, network adapter, or station; locate the source of the errors by looking at the module and port statistics; or replace the adapter.

Additional

Monitors the number of frames received on a particular interface that are an integral number of octets in length but do not pass the FCS check. This count does not include frames received with frame-too-long or frame-too-short error.
