Same here... a lot of times. My last experience with a dying port on a switch was a few days ago while JumpStart-ing Solaris via OBP. The process hung everywhere from RARP, BOOTP, TFTP and NFS... until we figured out the port on the switch was slowly dying. Funny thing was that this problem was masked by TCP's error correction mechanisms for quite some time and became only critical with UDP: the TCP connections were slow as hell, but since the machine wasn't used for high throughput anyway, the local junior admin assumed it was some kind of software/hardware error on the host. She saw the many input errors (Ierr= s) in netstat -i, but didn't know what to do about them. ;-) So yes, switches rarely stop altogether, the ports usually degrade, one by one. > Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] -cpghost. --=20 Cordula's Web. http://www.cordula.ws/
