Ira,
I don't understand your response. If this is true, then this is not
hrDeviceIndex as used by the printer and must be clearly indicated
as such and should not be called hrDeviceIndex.
Why does the index for the table not satisfy this requirement?
Ron

Hi Ron,
Going all the way back to the first Microsoft draft and ever since,
it's clear that the MS "port" entry has to have a separate device
index for each port, because the 'hr...' status objects have to be
separate for EACH port.
Remember the main MS model is NOT an embedded printer. It's either
an external network adaptor or a spooler. In both of these cases,
only ONE protocol is being exposed fore each "port".
This isn't a new restriction.
In the case of an external network adaptor, each "port" is literally
a different direct-connect printer.
Cheers,
- Ira

Ira,
Regarding your comment:
2. ppmPortHrDeviceIndex - This seems to imply an hrDeviceTable entry is
needed for each port on the system. Is this the expected behavior?
Or is this just the hrDeviceIndex of the printer?
Or is the the hrDeviceIndex for the network card?
<ira> For the Microsoft tool (TCPMon), EACH port (channel) has to
have a separate 'hrDeviceIndex' - this is different than typical
Printer MIB implementations, but it's a Microsoft tool limitation.
Note that Microsoft TCPMon _only_ supports LPR and Raw ports (no
other protocol is supported or contemplated according to co-editor
Mike Fenelon from the Microsoft Longhorn printing team), so this
only means two 'hrDeviceIndex' values at most (for each printer).
</ira>
I do not recall ever hearing this. It certainly is not clear from
the MIB text (see below) that this is the case. If this is true
then it is not really hrDeviceIndex that is indicated but is just
ppmPortIndex.
Also, for the printers I work with there will be a minimum of 10
ports reported. If IPP is enable, there will be a minimum of 15.
The maximum number will be 192.

From the MIB:
ppmPortHrDeviceIndex OBJECT-TYPE
SYNTAX Integer32 (0..2147483647)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The value of 'hrDeviceIndex' in the IETF Host Resources MIB
(RFC 1514/2790), to be used for status queries for this port if
the value of 'ppmPortSnmpStatusQueryEnabled' is 'true'.
If this object is zero, then monitoring applications MUST NOT
attempt status queries for this port in the IETF Host Resources
MIB (RFC 1514/2790) and/or IETF Printer MIB (RFC 1759/3805)."
REFERENCE
"hrDeviceStatus, hrPrinterStatus, hrPrinterDetectedErrorState i
n IETF Host Resources MIB (RFC 1514/2790).
prtChannelStatus in IETF Printer MIB (RFC 1759/3805)."
DEFVAL { 0 } -- no host device index
