    Hi,

    I suggest that the best guidance that the Port Mon MIB can
    give to users about status rollup (including from subunits
    like Channels) is in Section 2.2.13.2 "Overall Printer Status"
    and Appendix E (see below) of Printer MIB v2 (RFC 3805) and in
    the accompanying Top 25 matrix.

    Caution - it took four years to reach reasonable concensus
    on the Top 25 matrix - this is _not_ a good topic to address
    separately for Port Mon MIB.

    Cheers,
    - Ira

    Appendix E - Overall Printer Status Table

       The Status Table establishes a convention for the top 25 printer
       errors. The table defines a suggested relationship between various
       printer states and the variables Printer hrDeviceStatus,
       hrPrinterStatus, hrPrinterDetectedErrorState, prtAlertGroup,
       prtAlertCode and various sub-unit status variables (prtInputStatus,
       prtOutputStatus, prtMarkerStatus, prtMediaPathStatus and
       prtChannelStatus). This table is the recommended implementation of
       these variables. It is provided to guide implementors of this MIB
       and users of the MIB by providing a sample set of states and the
       variable values that are expected to be produced as result of that
       state. This information supplements that provided in Section
       2.2.13.2 "Overall Printer Status". This is not an exhaustive list
       rather it is a guideline.

       The definition of PrtSubUnitStatusTC specifies that SubUnitStatus is
       an integer that is the sum of 5 distinct values/states: Availability,
       Critical, Non-Critical, On-line and Transitioning. Thus when a non-
       critical alert or alerts are present the values for Availability,
       On-Line and Transitioning will be summed with the Non- Critical
       Alerts (8) value.

       The table was generated in landscape format and is located at
       ftp://ftp.pwg.org/pub/pwg/pmp/contributions/Top25Errors.pdf.
