What is swL2PortStCRCError?
Counts normal-sized received frames (64-1536 bytes) that had an invalid CRC checksum but weren't associated with a collision or receive error - a classic sign of a bad cable, connector, or NIC on this port that an admin should physically inspect.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.12 snmpwalk -v2c -c public <target> SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStCRCError
Get a specific instance (index 1):
