i do a sho vlan and i write down every vlan that is assigned to a prot.
Then i do a sho int trunk to see if there are any vlans i on the switch
that arnt assigned
I do this on both switches then i write down the vlans that are common to
each set.
I use that set of complete vlans to complete me sw tr all vlan command.
This method can trip yuu up if you add vlans to the devices in a later
task.

I also am a bit confused on the process of the pruning function. I
have
been labbing this up different ways and I can get the trunk allowed
command to work as it should. However, the pruning function on the
interface that is trunking doesn't appear to be pruned back on the
client. I still see all the vlans advertised (even though they are
not
being used). I thought that the pruning would cause the vlans to not
show up in the "show vlan" list of the client. Is this not the case?
Here is my config under the port that is trunking. VTP is set for
the
server and pruning is enabled..... Thoughts?
interface FastEthernet0/13
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2-999
switchport trunk pruning vlan 2-10
switchport mode trunk
switchport nonegotiate

You only need to remove vlan 8 from the prune eligible list on sw1
port
fa0/13 to solve problem 1 (switchport trunk pruning vlan remove 8).
Problem 2 is already solved by the vtp pruning that you enbaled on
both
switches. You do not need to play with the vtp allowed list to solve
these 2 problems. Test it out.
