Hi folks, Thursday (19 February 2004)
In the WBMM WG, we agreed we need a PWG 'extension' to Printer MIB v2
for support of:
(1) Multi-function services and devices; and
(2) Multi-function counters that Pete Zehler has proposed from Xerox.
After some discussion at this week's WBMM telecon, here are heirarchy
diagrams of a set of proposed PWG MIBs:
PWG Imaging System MIB
----------------------
|-----------| |-----------|
| System |...............................| System |
| (1) | 1-->n | Attribute |
|-----------| |-----------|
:
: |-----------| |-----------|
:.............| Service | | Service |
: 1-->n | |...........| Attribute |
: |-----------| 1-->n |-----------|

:.............| Device | | Device |

: |-----------| 1-->n |-----------|
:
: |-----------|
:.............| Locale |
: 1-->n | |
: |-----------|
:
: |-----------|
:.............| Alert |
1-->n | |
|-----------|
and one notification group:
Alert Trap - multi-function alerts for system/service/device
PWG Resource MIB
----------------
|-----------|
| General |
| (1) |

:

:.............| Resource | | Resource |
1-->n | |...........| Attribute |

PWG Media MIB
-------------

| General |
| (1) |
|-----------|
:
: |-----------| |-----------|
:.............| Media | | Media |
1-->n | |...........| Attribute |
|-----------| 1-->n |-----------|
This proposal captures the entire functionality of the (never completed)
MFPA MFP MIB, Scanner MIB, Image Processing MIB, by generalizing from
the Printer MIB v1/v2. It also adds service-level functionality.
Comments?
Cheers,

[some details of the proposal]
PWG Imaging System MIB
----------------------
* System group
- corresponds to (but does NOT import from) System group
in IETF Host Resources MIB (RFC 2790)
- top-level state, description, and counters, e.g.,
isSystemState OBJECT-TYPE
SYNTAX IsObjectStateTC
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The state of this Imaging System (e.g., idle)."
REFERENCE
"See: 'printer-state' in IPP/1.1 Model (RFC 2911);
'hrDeviceStatus' in Host Resources MIB (RFC 2790)."
::= { isSystemEntry 2 }
isSystemTotalAlerts OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Total system, service, or device alerts that have occurred
on this Imaging System."
::= { isSystemEntry 4 }
* System Attribute group
- based on Job Mon MIB (RFC 2707) and Finisher MIB attribute tables
- top-level counters (totals from Pete Zehler's counters), e.g.,
generalInputImages(75), -- INTEGER - counter
-- total images received by system, service, or device
generalImpressions(81), -- INTEGER - counter
-- total impressions printed by system, service, or device
- top-level description (most tables from Printer MIB v2), e.g.,
generalInputDefaultIndex(54), -- INTEGER - index or zero
-- default input tray, i.e., 'isXxxAttributeValueIndex'
-- see 'prtInputDefaultIndex' in Printer MIB v1
-- (RFC 1759) and Printer MIB v2 (IESG-approved) for usage
inputType(151), -- INTEGER - enumeration
-- input tray technology type (usually by feed mechanism)
-- see 'PrtInputTypeTC' in IANA Printer MIB
* Service group
- based on IPP/1.1 Printer (RFC 2911) and PWG Semantic Model
- corresponds to (but does NOT import from) Software Installed and
Software Running groups in IETF Host Resources MIB (RFC 2790)
- service-level state, description, and counters
* Service Attribute group
- based on IPP/1.1 Printer (RFC 2911) and PWG Semantic Model
- service-level counters (details from Pete Zehler's counters)
- service-level description (most tables from Printer MIB v2)
* Device group
- based on (but does NOT import from) Printer MIB v1/v2
- corresponds to (but does NOT import from) Device group
in IETF Host Resources MIB (RFC 2790)
- device-level state, description, and counters
* Device Attribute group
- based on (but does NOT import from) Printer MIB v1/v2
- device-level counters (details from Pete Zehler's counters)
- device-level description (most tables from Printer MIB v2)
* Locale group
- based on (but does NOT import from) Printer MIB v1/v2
- corresponds to Localization group in Printer MIB v1/v2
- system-level localization
* Alert group
- based on (but does NOT import from) Printer MIB v1/v2
- corresponds to Alert group in Printer MIB v1/v2
- system/service/device-level events
PWG Resource MIB
----------------
* Resource group
- based on WBMM Resource schema (from IPP Resource draft)
- resource-level state, description, and counters
* Resource Attribute group
- based on WBMM Resource schema (from IPP Resource draft)
- resource-level state, description, and counters
PWG Media MIB
-------------
* Media group
- based on IPP/1.1 Media (PWG 5100.3) and PWG Semantic Model
- media-level description and counters
* Media Attribute group
- based on IPP/1.1 Media (PWG 5100.3) and PWG Semantic Model
- media-level counters (details from Pete Zehler's counters)
- media-level description
