2950 stp

Please excuse my crude drawing. Isn't one of these ports suppose to go amber. I set up this configuration in a lab using xover cables, cleared vlan.dat and erased startup-configs. All port lights stayed green even after I trunked the ports.

Run the command:

show interface fa0/? switchport

They are probably set to dynamic desirable and therefore they configured themselves as trunks automatically. I hope this helps.

Nice diagram.

If you are referring to spanning tree disabling a port I think it depends on which model of switch you have whether the light turns amber or not.

do a
#sh int status

on each switch to see the statu if the ports are up

and then a

#sh spanning tree

to see what ports are getting blocked. I know on my 3550 and 3750 all ports stay green blocked or otherwise. unless they are physicaly down

Likewise on my two 3550's and 2950. Always green.
