ethTotalCRCAlignErrors
Module: SL-ETH-MIB
OID (symbolic): SL-ETH-MIB::ethTotalCRCAlignErrors
OID (numeric): 1.3.6.1.4.1.4515.1.1.1.4.1.8
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of packets received in the previous 24 hour 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 ethTotalCRCAlignErrors?
Counts properly-sized packets with a bad FCS (aligned or misaligned) received over the entire previous 24-hour period. A nonzero daily total here is often the first indicator an admin sees that prompts them to dig into the 15-minute intervals to find exactly when the errors occurred.
