Products (1)

  • Cisco cBR Series Converged Broadband Routers

Known Affected Releases

Gibraltar-16.10.2

Description (partial)

Symptom:
cBR-8 ifSpeed value is not calculated based on the formula in the DOCSIS specs (CM-SP-CCAP-OSSIv3.1-I 17-19120), it returns instead a more accurate OFDM speed calculation that considers NCP overhead.
This difference in calculation makes it harder to operate in a mixed vendor CMTS.

Conditions:
SNMP MIB gathering ifSpeed in cBR-8
