    Hi Larry,

    Two more bits about Host Resources MIB (RFC 2790)

    - System group (extends System group in MIB-II)
      contains the very useful attributes
      'hrSystemUptime' (since last boot) and
      'hrSystemDate' (date and time, with time zone)

    - Software Installed group (optional) contains
      'hrSWInstalledLastChange' (last change any s/w) and
      'hrSWInstalledName' (description of s/w element)

    Note that MS Windows has ubiquitously supported
    the Software Installed and (parallel) Software
    Running groups for some years, so this is useful
    for more than printers in a monitor.

    Larry, you are correct. The use of hrMIB was rather unfortunate in that it
    forced the munging of local resource indexing onto a networked device. For
    all intents and purposes, in the embedded network printer, the "host" IS the
    printer controller (there may still be implementations where the host is the
    NIC). The hrMIB is still useful in this context for helping distinguish
    internal printer resources like a storage device, for example.

    SubjectQuestion Re intended agent support for RFC3805

    Hello Harry,
    RFC3805 appears to be clearly intended to be supported by an agent on a
    platform with attached printers - as evidenced by using the index
    "hrDeviceIndex" in its tables.
    Is it also intended for implementation as an embedded agent within a
    printer? If so, then I would assume that "hrDeviceIndex" takes on one value
    that is local to the printer, and that value has nothing to do with the host
    resource index on the platform. Right?
    Thanks for any insights you can provide.
    Best Regards, Larry
