I recommend using the 'root primary' command. My reason is that there are
more parameters that are adjusted for network optimization by using this
macro. For example:
CAT1(config)#spanning-tree vlan 12 root primary
vlan 12 bridge priority set to 24576
vlan 12 bridge max aging time unchanged at 20
vlan 12 bridge hello time unchanged at 2
vlan 12 bridge forward delay unchanged at 15
Notice the timers for stp are checked to make sure they are correct for this
switch to be root for vlan 12. Also, should you go to '0' you leave no room
for a different switch later to become root on the network should that need
arise.

Hi Group,
If the question asks me to configure the switch as root switch for vlan
11, which of the below commands should be used?
- spanning-tree vlan 11 priority 0
- spanning-tree vlan 11 root primary
Both of them will work well but which one do you prefer?
Thanks
Phong
