Ok
I changed SW2's Fa0/11 and Fa0/18 to: duplex-full ( and at the oposite
side routers 6 & 7 )
Here's spanning-tree for SW2:

Should I find vlan 2567 in the output when typing "sh spanning-tree"?
Cause I can't find it, what is wrong?

Look at whatever spanning-tree is doing to see if it's something strange
(show spanning-tree) on switch 2.
Otherwise, my other question is what the heck are you running
half-duplex on a fast-ethernet port for?
On sw2, you can also force "switchport mode access" and "spanning-tree
portfast" to speed things up in case you hate waiting. :)

Yes I did create vlan 2567 using "vlan 2567"
I did this on task 1.2 page 14 ( in the proctor lab book ) It was done
on
SW3 and SW4 ( which where in transparent mode ) On page 16 connection
between SW3 and SW2 are closed and connection between SW4 and SW1 are
closed. Could this be causing this?
The strange thing is, when I remove the "switchport access vlan 2567"
from SW2, then I'm able to see the SW2 from both R6 and R7 ( using "sh
cdp neigh" ).
Does anyone have any ideas?
