dot3HCStatsFCSErrors
Module: EtherLike-MIB
OID (symbolic): EtherLike-MIB::dot3HCStatsFCSErrors
OID (numeric): 1.3.6.1.2.1.10.7.11.1.2
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: A count 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.
The count represented by an instance of this object is incremented when the frameCheckError status is returned by the MAC service to the LLC (or other MAC user). Received frames for which multiple error conditions pertain are, according to the conventions of IEEE 802.3 Layer Management, counted exclusively according to the error status presented to the LLC.
Note: Coding errors detected by the physical layer for speeds above 10 Mb/s will cause the frame to fail the FCS check.
This counter is a 64 bit version of dot3StatsFCSErrors. It should be used on interfaces operating at 10 Gb/s or faster.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is dot3HCStatsFCSErrors?
This 64-bit counter counts frames received on this interface that were a valid number of octets but failed the frame check sequence, serving as the high-capacity version of dot3StatsFCSErrors for 10 Gb/s and faster links. Admins use it on high-speed interfaces where the 32-bit counter could wrap too fast to be useful, treating a rising count as a sign of physical-layer signal integrity problems such as bad cabling or optics. For example, a climbing FCS error count on a 10G fiber uplink after a recent patch-panel change would point an admin toward checking that fiber connection or transceiver.
