  1. IPCDN Working Group DOCSIS/DVB MIB Merge Proposal Richard Woundy Cisco Systems March 28, 2000

  2. Basis of DOCSIS/DVB MIB Comparison • DOCSIS Cable Device MIB • RFC 2669 • DVB Cable Network Interface Unit MIB • draft-valentine-dubnetint-mib-00.txt

  3. DOCSIS/DVB MIB Merge Rationales • OpenCable and other ASTBs • Assume single CPU, single SNMP agent • ASTB reset vs. DOCSIS/DVB reset • Upstream traffic using DOCSIS vs. DVB • Consolidated NMS access, event logging • Consistent cable modem management • Common modem software, NMS apps

  4. Proposed Common MIB Object Groups • Basic Modem Control group • NM Access Control group (replace with SNMPv3 co-existence MIB) • Event Logging group • Ethernet/LLC Filtering group • IP Filtering group • IP ToS Mapping group • CPE Management group

  5. Basic Modem Control Group Objects • Modem type and role • Date and time • Modem reset control and count • Serial number • MIB version • Implementation set - what’s been implemented on this modem

  6. Proposed DOCSIS-only MIB Object Groups • DOCSIS Modem Control group • DOCSIS reset • Admin and operational status • Spanning tree control • DHCP/ToD/TFTP controls • SYSLOG control • DOCSIS Software Management group • Single software image management

  7. Proposed DVB-only MIB Object Groups • DVB Modem Control group • DVB reset • Admin and operational status • Euroloader control • DVB Software Management group • Multiple software image management • Static Route Table, DHCP relay groups • NAT and NAPT groups

  8. DOCSIS/DVB MergeMajor Issues • Are the MIB merger rationales valid? • Single-CPU, single SNMP agent, combined DOCSIS/DVB ASTB? • Software efforts that leverage a merger? • Is there support for a merged MIB? • DOCSIS buy-in? Euromodem buy-in? OpenCable buy-in? • What is the transition plan to the merged MIB?

  9. What is the next step? • Write internet-draft of proposed merged MIB? • Drop MIB merge, but document MIB comparisons? • Use effort as basis to review DOCSIS/DVB MIBs independently?
