<div class="WordSection1">However, I didn’t inmmediatly marked the old
switches as inactive, and some member ports that were no longer
connected were still associated to the old Switches. As a result the
member ports and switch MRTG graphs were OK, but the aggregated
overall graph did not graph anymore.<o:p></o:p>

got pointers about deactivating the old switches and do some clean up on

This is one of those situations where if the data source is incorrect,
there's a risk of running into problems :(<br><o:p> </o:p>

<ol style="margin-top:0cm" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0cm;mso-list:l0 level1
lfo1">Why the aggregated graph stops working if a Switch or port cannot
be polled by SNMP?</li></ol></div></blockquote><br>This is how MRTG
works. If you specify data endpoints which don't exist, then MRTG
doesn't handle aggregate graphs. It's a known problem with MRTG.<br><br><blockquote
type="cite" style="word-wrap:break-word"><div class="WordSection1"><ol
style="margin-top:0cm" start="1" type="1"><li class="MsoListParagraph"
style="margin-left:0cm;mso-list:l0 level1 lfo1">Given that the member
and switch graphs were OK and the information exists, is it possible to
rebuild the aggregated graph to include the missing data? (Around 30hrs)</li></ol></div></blockquote><br>This
isn't easy. It's possible to add up the various columns in the mrtg log
files, but you'll likely find that the 5m maximum in+out figures will
be incorrect due to how mrtg calculates them. The average in/out figures
will be correct though.<br><br><blockquote type="cite"

style="margin-top:0cm" start="1" type="1"><li class="MsoListParagraph"
style="margin-left:0cm;mso-list:l0 level1 lfo1">What would be the
recommended procedure to remove a Switch without loosing historical
graphs? (Right now the switches are inactive, but still in IXP Manager)</li></ol></div></blockquote><br>Two
options here: you can replace a switch and use the same switch profile,
or you can leave them defined as active in IXP Manager, but de-select
the "poll" button. <br><br><blockquote type="cite"

recommended procedure to upgrade a member with 3x 10G ports in LAG to a
100G port, without loosing historical graphs?</li></ol></div></blockquote><br>If
you delete the 3 physical ports in the virtualinterface, then add the
new 100G port on the new switch, it should keep the aggregate intact.1<br><br>Nick<br><br><br><blockquote
