This example shows how to enable STP on VLAN 5:
switch# config t
switch(config)# spanning-tree vlan 5
switch(config)# exit
switch#
Do not disable spanning tree on a VLAN unless all switches and bridges in the VLAN have spanning tree

disabled. You cannot disable spanning tree on some switches and bridges in a VLAN and leave it enabled
on other switches and bridges in the VLAN. This action can have unexpected results because switches
and bridges with spanning tree enabled will have incomplete information regarding the physical topology
of the network.
