Re: Cisco 3500XL port state problem
the only guess I have is that there may be a speed/duplex issue that's causing errors and then the port is shut down due to error state. and that you have a very short timeout set on the port.
are you able to logon to the switch (either SSH/Telnet or using the serial cable?)
if you are then the switch will tell you what's going on!
logon, to the switch
then type sh int
that'll show you the interfaces on the switch. and what they are doing, and a error count on the interfaces.
you can look at a specific switch using sh int fa0/0/1 (to query port 1)
but if your switch is Gb enabled that command would be show interface ge0/0/1
(this little discrepency is why I don't suggest just typing this first)
