ssp2Crc
Module: CODIMA-EXPRESS-MIB
OID (symbolic): CODIMA-EXPRESS-MIB::ssp2Crc
OID (numeric): 1.3.6.1.4.1.226.3.2.1.1.2.2.6.1.23
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of CRC/Alignment Errors on Port 2. 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 ssp2Crc?
This read-only Counter32 tallies CRC and alignment errors seen on physical Port 2 of the CODIMA switch. A rising count means frames are arriving damaged (bad checksum) or not ending on an 8-bit boundary, which points to a cabling, duplex-mismatch, or failing NIC problem on whatever is plugged into Port 2. For example, if ssp2Crc climbs by several hundred counts an hour while other ports stay flat, an admin would suspect a bad patch cable or a half-duplex mismatch on the device connected to Port 2 specifically.
