This has been a very long day, after a lightning storm we started to
have towers randomly drop for 2-10 minutes with no consistency as to
where, how how long. The tower that was affected by last nights
lightning restarted (locally) so that wasn't it. The outages were so
extensive that at one
Forbes,
Can you give me a little more info on the setup of your network? Are
you layer 2 throughout your backhauls and tower sites? I have seen OSPF
flapping causing some weird issues on layer 3 networks. If you look at
the routers in the tower site, do you see anything in the log as to what
If it's all layer 2 bridge,maybe a second dhcp server running? Are you running
dhcp?

Or did a customer plug their CPE in to the wrong side of a home router which
is now giving out DHCP addresses?

I got a nice little email from Exalt about their new product, without
actually saying anything about it.
Any specification sheets out there?
Top speed in different bands?
Price ranges?

That's my suspicion how do you block that?!

Nope we static (private IP) nearly the entire network, one static for
their radio and one static for them to put in their router for us to
see that they can surf.

Thanks Eric,
We run a 2811 Cisco core router that feeds a Vyatta server for handing
out private static and public addresses which runs into a Mikrotik
bandwidth unit then over six backhauls to various towers from our head
end. Six towers relay to the next tower down. We have about 70 Public
Are they really down, or can you just not get to them? That is, are the
customers calling that they are down?
Do you use dynamic routing such as RIP or OSPF? If so, I would suspect
something is making them drop and reestablish routes.
Accept and drop do what they say for traffic destined for
Forbes,
I remember seeing something similar to this on the list a few months back.
Turned out he guy was running a bridged network and water got into the
Ethernet connector on a Bullet and was causing Layer2 broadcast storms on
the network. Very similar results to what you are reporting.

If it is bridged a single router plugged in backwords can bring down the
whole network. Some 750¹s would be a good fix.When I had HighGain Aps
as bridges we would run into this problem as well. I never figured it out
because we eventually went to MT aps.

Sounds a lot like a proxy arp issue where a device is trying to answer
for all the other devices and clearly on a big network that is not
going to work well.

Wow very interesting hypothesis since it happened right after a
lightning storm with heavy rain. Trouble is I shut off all six
backhauls and started turning them on one by one until I had a IP
conflict warning then turned that one off, the IP conflict happened
again, yes I did arp -d to clear
Sounds like you need some filtering bridges to help you in the
meantime. Drop some in the network and add some rules for DHCP and such.
You don¹t have to re-address.

Forbes,
Another thing to check, do you have any switches that do POE? Make sure you
don't have a CAT5 wire with water getting inside and traveling all the way
down into your switch and dumping water in there.

Hey whoever forwarded my issue to Brett thanks, he pointed out how to
isolate individual bridges with WireShark. I did that and found the
tower, it's too late today but having that tower down brought the rest
of the system back up. As Marlon said so will you be routed
tomorrow? Well maybe
