OID (numeric): 1.3.6.1.4.1.33.11.1.1.3
Node type: OBJECT-TYPE
Type: Counter

Description: A count of frames received on a particular interface that are an integral number of octets in length that do not pass the FCS check.
What is etherFCSErrors?
This is a running count of received frames on an MRV InReach Ethernet interface that are a whole number of octets but still fail the CRC check. Admins use it to detect data corruption on the wire connected to the InReach device, often pointing to electrical noise or a bad cable. A sudden rise in etherFCSErrors after re-cabling an InReach unit's uplink would suggest the new cable is introducing signal corruption.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.33.11.1.1.3 snmpwalk -v2c -c public <target> MRV-IN-REACH-ETHERNET-MIB::etherFCSErrors
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.33.11.1.1.3.1 snmpget -v2c -c public <target> MRV-IN-REACH-ETHERNET-MIB::etherFCSErrors.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> etherFCSErrors.1
