Hey guys,

Thanks for the help troubleshooting.

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.

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.

Thanks again!
-Bill

Hi David,
Yup, I know, I'm not using vlans now. What I meant is that when I tinkered with it, I screwed wired connections.
Hence I offered a working-ethernet config to William.
William, did you have any luck fixing your issue?

    you have vlans disabled in this config "option enable_vlan 0"

    if you want to use vlans > 15 you need "option enable_vlan4k 1" as

        I recently played with VLANs and screwed up it's switching
        capability
        exactly as you say.
        I managed to fix it by restoring the default setup in
        /etc/config/network
        (Especially config switch_vlan and ports)

        Compare your /etc/config/network with what I have (and works):
        config switch
               option name     rtl8366s
               option reset    1
               option enable_vlan 0
               # Blinkrate: 0=43ms; 1=84ms; 2=120ms; 3=170ms; 4=340ms;
        5=670ms
               option blinkrate        2
               option max_length 3

        config switch_vlan
               option device   rtl8366s
               option vlan     1
               option ports    "0 1 2 3 5t"

        config switch_port
               # Port 1 controls the GREEN configuration of LEDs for
               # the switch and the section does not correspond to a real
               # switch port.
               #
               # 0=LED off; 1=Collision/FDX; 2=Link/activity; 3=1000 Mb/s;
               # 4=100 Mb/s; 5=10 Mb/s; 6=1000 Mb/s+activity; 7=100
        Mb/s+activity;
               # 8=10 Mb/s+activity; 9=10/100 Mb/s+activity; 10: Fiber;
               # 11: Fault; 12: Link/activity(tx); 13: Link/activity(rx);
               # 14: Link (master); 15: separate register

               option device           rtl8366s
               option port             1
               option led              6

        config switch_port
               # Port 2 controls the ORANGE configuration of LEDs for
               # the switch and the section does not correspond to a real
               # switch port.
               #
               # See the key above for switch port 1 for the meaning
        of the
               # 'led' setting below.

               option device           rtl8366s
               option port             2
               option led              9

        config switch_port
               # Port 5 controls the configuration of the WAN LED and the
               # section does not correspond to a real switch port.
               #
               # To toggle the use of green or orange LEDs for the WAN
        port,
               # see the LED setting for wndr3700:green:wan in
        /etc/config/system.
               #
               # See the key above for switch port 1 for the meaning
        of the
               # 'led' setting below.

               option device           rtl8366s
               option port             5
               option led              2

            Hello,

            Just wanted to see if anyone has seen an issue like this:

            I have a 3800 running Sugarland at a remote site. It was
            running nice and
            reliably, connected to the local network by a VLAN trunked
            connection (I
            have interfaces for the default VLAN, and VLANS 100 and
            200 passing
            through). Last night it suddenly stopped working. There
            seems to be no data
            flowing through the switch at all, even though I can ssh
            to the router,
            reboot, poke at it, etc. from over the Internet.

            I see no error messages regarding the switch in the logs
            or dmesg. Anyone
            else see a 3800 switch crap out unceremoniously?

            Thanks,
            Bill Katsak
