Power supply issue...the switch dies... Memory recall issue sounds more like your problem. Connect hyperterm to Switch port...do you get memory errors printed on screen. -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Chaiket, Thom Sent: Tuesday, February 24, 2009 12:00 PM To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] network storm Hi List-- We are seeing the same symptoms (synchronized blinking of CPU/MGR/RPS lights on one MESH switch) described in the earlier post of this chain. However, powering down/up didn't do the trick for us. I reached out to Tech Support and was informed that our switches fell into that category affected by the power supply issue (a notification was out sometime last year, and our field technician then verified that these switches were okay before they were installed. ???) All in all, we are going to get these switches replaced VERY SOON. Other than cycling power, has anyone done anything successfully to get the switches back up temporarily or otherwise?

I think I have officially reached the limits of my knowledge. But, having never let not knowing stop me from speaking (or typing), I'll throw this out. We had the COMEX Multicast Suppession limits on our network set up 64Kb/sec, and it worked fine, and was pretty much impervious to a COMEX multicast storm (the silver bullet for I/A processors). We upped that to 128 Kb/sec while troubleshooting a problem that ultimately ended up being a bad ZCP, but based on the network sniffing we did on our system, 64kb/sec is more than enough bandwidth for COMEX Multicast for our application. Your mileage may vary. To the best of my knowledge (see "limits" above), the COMEX multicast is only used when initially opening displays on a workstation, and when ZCPs/FCMs boot up (not sure about that one). Otherwise, the COMEX multicast traffic is really, really, really, low. But, as Mike stated below, if the normal COMEX multicast traffic doesn't get through, you are going to have some issues, primarily with workstations. Ain't switches fun?
