Description:
xDSL Down stream CV (CRC errors).
What is cmEthernetNetPortHistoryXdslDsCv?
This read-only counter tracks the cumulative count of CRC errors (code violations) detected on the downstream xDSL connection for an Ethernet port, collected as historical performance data. An operator monitors this to assess the quality and stability of the xDSL link—high CRC error counts indicate line quality problems or electrical interference. This metric helps determine if the line needs closer inspection or replacement.
