<p>Hello</p>
<p> we have some hosts setup with reservations , which are instead
getting a pool address. </p>
<p><br>
</p>
<p>this printer which should have <span
style="font-family:monospace">10.1.25.132 but got </span><font
face="monospace">10.1.25.183 . this printer and another get
used overnight so we had to temporarily change the IP address at
the cups print server . </font><b><font face="monospace"><br>
</font></b></p>
<p><br>
</p>
<p>In the mean time we'll look at the programming on some of our
recently replaced managed switches. I suspect pvid is incorrect
on some ports or dhcp relay setting... I had been working on
network security settings - like limiting which vlans are
accessible from some downstream switches..<br>
</p>
<p> in addition we use proxmox to manage our virtual machines.
all debian KVM's which used dhcp-client had wrong addresses .
windows are okay. LXC's are okay. a lot of testing and debugging
was done. details are at

</p>
<p>here is some debugging info for a host that has this
reservation. <b> If anyone has I suggestion on where to look to
solve the issue I am all ears</b>! [ except the next 7 hours
for sleep.]<br>
