    Hey guys,<br>
    <br>
    Thanks for the help troubleshooting.<br>
    <br>
    So it turns out that one of the machines on the restricted VLAN
    (this is a small charity/nonprofit, this VLAN is for their clients
    to browse the web) got infected with something and was generating a
    mind-blowing amount of broadcast traffic. Since the cero router is
    the device that routes between the VLANs, the switch was getting hit
    with all of this traffic and locking up.<br>
    <br>
    The fact that I had all three VLANs trunked over one port made it so
    that I couldn't see anything to figure out how to fix it...once I
    got someone on site to start poking at cables, I was able to split
    each VLAN to a different wire, then was able to get to the Dell
    managed switch interface and figure out who was the culprit.<br>
    <br>
    Thanks again!<br>
    -Bill<br>

                  <br>
                  Just wanted to see if anyone has seen an issue like
                  this:<br>
                  <br>
                  I have a 3800 running Sugarland at a remote site. It
                  was running nice and<br>
                  reliably, connected to the local network by a VLAN
                  trunked connection (I<br>
                  have interfaces for the default VLAN, and VLANS 100
                  and 200 passing<br>
                  through). Last night it suddenly stopped working.
                  There seems to be no data<br>
                  flowing through the switch at all, even though I can
                  ssh to the router,<br>
                  reboot, poke at it, etc. from over the Internet.<br>
                  <br>
                  I see no error messages regarding the switch in the
                  logs or dmesg. Anyone<br>
                  else see a 3800 switch crap out unceremoniously?<br>
                  <br>
                  Thanks,<br>
