rEtherStatsCRCAlignErrors
Module: GBNServiceRMON-MIB
OID (symbolic): GBNServiceRMON-MIB::rEtherStatsCRCAlignErrors
OID (numeric): 1.3.6.1.4.1.13464.1.2.3.2.1.1.1.8
Node type: OBJECT-TYPE
Type: Counter
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 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 rEtherStatsCRCAlignErrors?
This counter tallies properly-sized packets (64-1518 octets) that failed either a CRC check or had a non-integral number of octets (alignment error). A steadily climbing value points an admin toward a bad cable, duplex mismatch, or failing NIC on that segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.13464.1.2.3.2.1.1.1.8 snmpwalk -v2c -c public <target> GBNServiceRMON-MIB::rEtherStatsCRCAlignErrors
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.13464.1.2.3.2.1.1.1.8.1 snmpget -v2c -c public <target> GBNServiceRMON-MIB::rEtherStatsCRCAlignErrors.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> rEtherStatsCRCAlignErrors.1
