etherStatsCRCAlignErrors
Module: RMON-MIB
OID (symbolic): RMON-MIB::etherStatsCRCAlignErrors
OID (numeric): 1.3.6.1.2.1.16.1.1.1.8
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The total number of packets received that had a length (excluding framing bits, but including FCS octets) of 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 etherStatsCRCAlignErrors?
The count of received packets between 64 and 1518 octets that had a bad Frame Check Sequence — either with a whole number of octets (an FCS error) or a fractional number (an alignment error); a rising count typically points to a bad cable, connector, or duplex mismatch on the monitored segment.
Examples
