Michael,
If you think about why you need a trunk, then the output would make sense. The
trunk is used to pass traffic for multiple VLANs. These VLANs may or may not
be located on remote switches.
Since you have pruning enabled, VLANs that are not needed on the trunk (those
that are not active on the remote switch) are removed. So lets look at your
example again:
SW1 - Active VLANs, 1-3; going over the trunk (to reach SW2), 1,2,4.
SW2 - Active VLANs, 1,2,4; going over the trunk (to reach SW1), 1-3.
The only VLANs that are allowed over the trunk are those that are active on
the REMOTE switch, because that switch still needs to receive traffic for
those VLANs.
HTH,
Eugene Ward
