Powerconnect 3348 - auto port disable?
I have several ports that seem to have automatically disabled themselves. For the first two, I had a router connected that had a duplex mismatch with the switch. This of course generated a lot of errors. I didn't really notice any performance issues but I did notice it when the switched stopped allowing communication on that port (our companys internet connection went down). I thought it was just a bad port so I moved it to another one. The same thing happened on the new port about a day later. At that time I dug a little more and found the duplex mismatch.
My question is - does the switch have a certain error limit that it will allow that if passed, will result in the port being disabled? If so, is there a way to turn the port back on (on the second failure I tried plugging the router back in the original port but it still didn't work)?
Thanks
Cliff

Thanks for the reply.
I know there was a negotiation issue. The router that was plugged in was an older router that had a hardcoded 10mb full duplex interface. The switch was set to auto and config'd itslef as 10/half. Hence the errors on the interfaces. Is there an auto shutdown or auto blocking feature after a certain amount of errors though? Because the router was up and running for several days before it suddenly stopped working.
I will try the no shutdown command to see if I can bring those interaces back online. Thanks for the help!
