Thanks Tim, I'm not sure yet.  but how do you mean you are 90% routed?  Does each of your APs go directly to a router?  I only have one headend, w/ 1 canopy 900 on an omni, 3 canopy 2.45's each on a 120* sector, thats it.  They are all plugged into a CMMmicro, from there to a Netgear switch, to a Mikrotik router, to a back haul (tranzeo 5a) to a CLEC fiber for access - its simple but it has worked well, until this mess.

Ron,
 
Are you seeing icmp to other IP's that are unreachable along with the icmp to 0.0.0.0 ?
 
I have seen this in the past and looked like it was coming from a linksys router. I suspected the router was randomly replying to other's IP's, basically causing loops. To isolate I had to disable different AP's to discover which AP it was originating from, then acl each client until I could isolate to a client, long process in between network hangs. The last time this happened to me 90% of my network was bridged. Now I am 90% routed and have not seen the problem

It is probably peer to peer traffic. That can take a network down very quickly. You will have to hunt down which user is hammering your network. Probably BitTorrent traffic if I were guessing.

To all,

 

I am having a network storm, the first.  All activity light switches on the wireless net are flashing like crazy, both at the data center and customer sites, may not mean much, but it has not happened before.  There is a huge amount of traffic on the canopy sys.  Others have discussed an ICMP storm w/ a (0.0.0.0) address that comes from Linksys & Netgear routers.  There are about 20 on my net, of 90 users.

 

I am a know-nothing at this, and really a hardware/RF guy.  Not familiar with Ethereal or other SW that monitors the net.  What are you all using?  Where do I get it?  What are your thoughts and advice?

 

Any help or advice you could offer would be greatly appreciated.  I'll do whatever you all advise.

 

Ron Wallace
