<br><font size=2 face="sans-serif">Scott,</font>
<br>
<br><font size=2 face="Arial">Might be a broadcast storm, so finding the source of it would solve the problem. I'd add storm-control commands to the user ports in order to see if any of the devices sends large amounts of broadcast (maybe a loop of some sort)</font>
<br>
<br><font size=2 face="Arial">storm-control broadcast level 5.00 action shutdown </font>
<br>
<br><font size=2 face="sans-serif">The command would shut down any port that sends more than 5 percent of broadcast which is very high on a 100Mb interface. So you might find the source. The other idea about changing the switch is also a good idea.</font>
<br>
<br><font size=2 face="sans-serif">HTH</font>

<br>
<br><font size=2>I'm really going to show how dumb I am but I'm too close to the problem.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>I have a 3560 48 port 10/100 PoE switch that connects about 6 phone back to an other 3560 via SX.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>The switch / phones I'm having problems with keep loosing connections and therefore the phones keep reseting.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>I found the one switch with err-disable do to flapping. So I replaced the SX and put it in a different Gig sfp slot.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>Still having the issue. </font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2> Look to be a broadcast storm by the link lights. So I unplugged ports until the lights went back to normal. Follow the cable back to a phone à</font><font size=3>PC. Plug it back in and the lights still looked fine.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>telnet into the switch and I'm seeing the gig link Broadcast and multicast increment at a rate of `100 per sec. NO other switch ports are incrementing anywhere close to this.</font>
<br>
<br><font size=2> </font>
<br>
<br><font size=2>Is this a bad switch? Do I have a bad run of fiber? What can I do to trouble shoot more?</font>
