Jason,
e.g.
If several switches have been trunked and let's say vlan 1 exits in all
these switches, any w/s (connected to vlan 1) sending a broadcast will
reach all devices in vlan 1 across all switches. On the other hand, if some
of these switches don't require to have vlan 1 configured, the sensible
thing to do is to prune vlan 1 from the trunk going to these switches in
order to save bandwidth. Some time ago, I explained that instead of pruning
(that have some issues) is better to clear undesire vlans from the trunk.
Hope this is of help.
Regards,
Frank.
