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>

<div>Yup, I know, I'm not using vlans now. What I meant is that
when I tinkered with it, I screwed wired connections.</div>

<div>William, did you have any luck fixing your issue?</div>

I recently played with VLANs and screwed up it's
switching capability<br>
exactly as you say.<br>
I managed to fix it by restoring the default setup in
/etc/config/network<br>
(Especially config switch_vlan and ports)<br>
<br>
Compare your /etc/config/network with what I have (and
works):<br>
config switch<br>
option name rtl8366s<br>
option reset 1<br>
option enable_vlan 0<br>
# Blinkrate: 0=43ms; 1=84ms; 2=120ms; 3=170ms;
4=340ms; 5=670ms<br>
option blinkrate 2<br>
option max_length 3<br>
<br>
config switch_vlan<br>
option device rtl8366s<br>
option vlan 1<br>
option ports "0 1 2 3 5t"<br>
<br>
config switch_port<br>
# Port 1 controls the GREEN configuration of LEDs
for<br>
# the switch and the section does not correspond
to a real<br>
# switch port.<br>
#<br>
# 0=LED off; 1=Collision/FDX; 2=Link/activity;
3=1000 Mb/s;<br>
# 4=100 Mb/s; 5=10 Mb/s; 6=1000 Mb/s+activity;
7=100 Mb/s+activity;<br>
# 8=10 Mb/s+activity; 9=10/100 Mb/s+activity; 10:
Fiber;<br>
# 11: Fault; 12: Link/activity(tx); 13:
Link/activity(rx);<br>
# 14: Link (master); 15: separate register<br>
<br>
option device rtl8366s<br>
option port 1<br>
option led 6<br>
<br>
config switch_port<br>
# Port 2 controls the ORANGE configuration of
LEDs for<br>
# the switch and the section does not correspond
to a real<br>
# switch port.<br>
#<br>
# See the key above for switch port 1 for the
meaning of the<br>
# 'led' setting below.<br>
<br>
option device rtl8366s<br>
option port 2<br>
option led 9<br>
<br>
config switch_port<br>
# Port 5 controls the configuration of the WAN
LED and the<br>
# section does not correspond to a real switch
port.<br>
#<br>
# To toggle the use of green or orange LEDs for
the WAN port,<br>
# see the LED setting for wndr3700:green:wan in
/etc/config/system.<br>
#<br>
# See the key above for switch port 1 for the
meaning of the<br>
# 'led' setting below.<br>
<br>
option device rtl8366s<br>
option port 5<br>
option led 2<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>
Bill Katsak<br>
