PMP> Sketch of PPM MIB with new Printer table

[McDonald, Ira]

Hi,                                                Sunday (17 July 2005)

Based on feedback from the Printer Port Monitor Interop event last week,
below is a brief sketch of a revised PPM MIB with three object groups:

(1) General - scalars - language tag and counters
    - add ppmGeneralNumberOfPrinters (entry count for ppmPrinterTable)
    - keep ppmGeneralNumberOfPorts (entry count for ppmPortTable)
    - remove ppmGeneralPreferredPortIndex (add to ppmPrinterTable)

(2) Printer - table - list of printers on system
    - keep Printer-specific elements from previous ppmPortTable
        (for ENA or Network Spooler)
    - maps one-to-one to Printers in Host Resources MIB and Printer MIB
        (via ppmPrinterHrDeviceIndex, if non-zero)
    - rename ppmPortSnmpStatusQueryEnabled to ppmPrinterSnmpQueryEnabled
        (to stay within 31 characters for portability across compilers)

(3) Port - table - list of logical ports on each printer
    - indexed by ppmPrinterIndex and ppmPortIndex
    - keeps Port-specific elements from previous ppmPortTable

All tables were reordered to follow Printer MIB and PWG Semantic Model
conventions - state, name, description, type, other stuff - see below.

I plan to post clean ASN.1 for this revision by Monday evening.

Comments?

Cheers,
- Ira
