What is pbcCmtsIfUpstreamCrcErrors?
This counter tracks CRC errors detected on an upstream channel, meaning frames whose payload failed the cyclic redundancy check on arrival. Admins watch this alongside HCS errors to gauge overall upstream signal quality and catch a noisy channel before customers notice.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5987.2.2.1.3.2.1.7 snmpwalk -v2c -c public <target> PBC-CMTS-MIB::pbcCmtsIfUpstreamCrcErrors
Get a specific instance (index 1):
