question about spanning-tree config.
I have a four switches layer-2 setup running RSTP. For one of the vlan spanning tree is not optimized and root switch is selected be default (lowest MAC) process.
1. What will happen if I configure the "spanning-tree primary" for a VLAN on the switch that is already the root for this VLAN? COnsidering that I am using RSTP would there be any impact to the user?
2. What will happen if I configure a differnent switch as "spanning-tree primary"? Would it take more time to converge? User impact?
3. A switchport is in default "dynamic desirable" mode. It is configured for access vlan "switchport access vlan .." and is supposed to be in access mode but does not have the mode defined. If I go ahead and apply the command "switchport mode access " would it have any impact?
