rEtherHistoryCRCAlignErrors
Module: SWITCH-RMON-MIB
OID (symbolic): SWITCH-RMON-MIB::rEtherHistoryCRCAlignErrors
OID (numeric): 1.3.6.1.4.1.8886.6.1.22.2.2.1.9
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of packets received during this sampling interval that had a length (excluding framing bits but including FCS octets) between 64 and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a non-integral number of octets (Alignment Error).
What is rEtherHistoryCRCAlignErrors?
This counter records CRC/alignment errors (packets 64-1518 octets with a bad FCS) that occurred during this specific sampling interval. Charting this across buckets helps correlate a spike in errors to a specific time, useful for tying a cabling or duplex issue to when it started.
