Though A/B/C class scheme is supposed to be retired, I'd rather stick to standard masking as initial step, just because not all software, especially legacy software, may implement non-standard masking 100% correctly. (As a matter of fact I have a set-up that uses A-class private subnet, but it uses standard-size A class masks, i.e. 255.0.0.0 rather than 255.255.255.0.)<br><br>Fix this for a start and see what happens.<br><br>This said, it is suspicious that DELQA MAC address does not appear in list of MAC addresses seen by the bridge and that tap0 counters are all 0.<br><br>But begin by fixing masks, do some pinging, and if it still does not work repost new data.<br>Also see if SHOW DEVICE XQ /FULL indicates any errors.<br><br>- Sergey<o:p></o:p></p><div><div><div><div><p class=yiv559835411msonormal> <o:p></o:p></p><div><div class=MsoNormal align=center style='text-align:center'><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'><hr size=1 width="100%" align=center></span></div><p class=yiv559835411msonormal style='margin-bottom:12.0pt'><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> "<a href="mailto:david.d.miller@att.net">david.d.miller@att.net</a>" <<a href="mailto:david.d.miller@att.net">david.d.miller@att.net</a>><br><b>To:</b> <a href="mailto:simh@trailing-edge.com">simh@trailing-edge.com</a><br><b>Sent:</b> Tue, September 4, 2012 10:10:52 AM<br><b>Subject:</b> Re: [Simh] Connecting to Ethernet</span><o:p></o:p></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td valign=top style='padding:0in 0in 0in 0in'><p class=yiv559835411msonormal>Sergey<br><br>I printed the data you asked for and made no changes to VAX because they looked OK to me.
