mleCrc
Module: CODIMA-EXPRESS-MIB
OID (symbolic): CODIMA-EXPRESS-MIB::mleCrc
OID (numeric): 1.3.6.1.4.1.226.3.2.1.1.3.1.4.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of CRC/Alignment Errors. CRC errors are frames which have been damaged. The Cyclic Redundancy Checksum used to confirm the validity of the frames contents shows that the frame is not valid. Alignment Errors are frames which are misaligned, a frame which does not end on an 8-bit boundary is considered an Alignment Error. A value of 4294967294 indicates unknown.
What is mleCrc?
This read-only Counter32 counts CRC and alignment errors, i.e. damaged or misaligned frames, attributed to this row's MAC address (MacIndex) in the mle Ethernet-error history table. Because this is scoped to one host in the matrix rather than a whole port, an admin can tell whether checksum failures are coming from a specific machine's bad NIC versus a shared cabling problem affecting everyone. If mleCrc rises for a particular server's row while its neighbors in the mle Ethernet-error history table stay at zero, an admin would swap that server's NIC before touching the switch port it plugs into.
