Re: DNS Blues
Cisco switches, out of the box, have portfast disabled. What yo can do is
watch the switch when you start up the computer. The port will stay "amber"
until spanning-tree has determined that allowing traffic won't create loop.
If your computer boots up (newer comptuers with XP boot in about 15 seconds)
before the port status light on the switch goes green, that could be an
issue. To fix it, just console into the switch, enter config mode, change to
the interface and issue the command "no span portfast".
