The idea would be to at least minimally describe some best practices for MIB usage, which would result in the host obtaining the required information using the smallest SNMP query and response packet transmission overhead possible.<o:p></o:p> <o:p> </o:p> In case people are wondering how dramatic a reduction in PPM I have observed when SNMP traffic is significant (host trying to determine whether device is in error or not – multiple queries are sent asking more and more specific questions of the printer MIB), I have seen printers and MFP’s with rated speeds in the 75 – 125 PPM range reduced to achieving actual throughput in the 10 to 20 PPM range.<o:p></o:p> <o:p> </o:p> HTH<o:p></o:p> <o:p> </o:p> Best Regards,<o:p></o:p> <o:p> </o:p> /Paul<o:p></o:p> <div> --<o:p></o:p> <tt>Paul Tykodi</tt> <tt>Principal Consultant</tt> <tt>TCS - Tykodi Consulting Services LLC</tt> <tt>Tel/Fax: 603-343-1820</tt> <st1:City w:st="on"><st1:place w:st="on"><tt>Mobile</tt></st1:place></st1:City><tt>:  603-866-0712</tt> <tt>E-mail:  <a href="mailto:ptykodi@tykodi.com">ptykodi@tykodi.com</a></tt> <tt>WWW:  </tt><tt><a href="http://www.tykodi.com/" target="_blank">http://www.tykodi.com</a></tt><o:p></o:p> </div> <div> <div class=MsoNormal align=center style='text-align:center'> <hr size=2 width="100%" align=center tabindex=-1> </div> From: pmp-owner@pwg.org [mailto:pmp-owner@pwg.org] On Behalf Of Bergman, Ron Sent: Tuesday, February 14, 2006 7:02 PM To: pmp@pwg.org Subject: PMP> Minutes of the MFP Teleconference 20060214<o:p></o:p> </div> <o:p> </o:p> The minutes can be found at: <o:p></o:p>         <a href="ftp://ftp.pwg.org/pub/pwg/pmp/minutes/mfp/MFP_Minutes_20060214.pdf">ftp://ftp.pwg.org/pub/pwg/pmp/minutes/mfp/MFP_Minutes_20060214.pdf</a> <o:p></o:p> Ron Bergman Chairman, Printer MIBs Working Group <o:p></o:p> </div> </body> </html>
