What is cmDSLYesterdaysRxCRCErrors?
This read-only PerfTotalCount reports the count of frames received with CRC checksum errors on the DSL port, scoped to the full previous calendar day's totals for the DSL port. Operationally, CRC errors are a direct measure of line-quality problems, since they indicate data was corrupted somewhere on the copper loop. For example, pulling yesterday's total CRC-error count gives an admin a same-day-yesterday baseline to compare against today's numbers when judging whether a fix actually helped.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1996.10.7.3.1.7 snmpwalk -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmDSLYesterdaysRxCRCErrors
Get a specific instance (index 1):
