ethCurrentCRCAlignErrors
Module: SL-ETH-MIB
OID (symbolic): SL-ETH-MIB::ethCurrentCRCAlignErrors
OID (numeric): 1.3.6.1.4.1.4515.1.1.1.2.1.7
Node type: OBJECT-TYPE
Type: Counter64
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 ethCurrentCRCAlignErrors?
Counts properly-sized (64-1518 byte) packets received during the current interval with a bad frame check sequence, whether aligned (FCS error) or misaligned (alignment error) to an octet boundary. A rising count here usually points to a cabling, connector, or duplex-mismatch problem on this segment right now.
