Is there a difference between the options:
a) making a switch the root spanning-tree by doing this:
spanning-tree vlan 22 root
OR
b) making a switch the root spanning-tree by
spanning-tree vlan 22 priority 4096 (whereas the other switch is 8192
practically speaking, what is the difference between the two ways of assigning spanning-tree preference?
Also when changing the priority (or making the other switch a ROOT), is there any outage for the traffic to traverse through the other path?
