Like Bill, I am also curious about your statement:
"Xerox engineers believe that this is one of several instances where
the Printer MIB Channel table is 'broken' in its references to the
Interfaces table (ie, LPR has no clue whether the Ethernet or Token
Ring LAN adapters delivered a given job)."
Can you share some insights as to why Xerox wants to know exactly which
interface was used to deliver, say, an LPR job? I realize that in the
realm of statistics, then this might be useful to a few folks. But are
there any other reasons why you need this info?
