Group,
I just want to make sure I am understanding something. I am sure I do, but
the warm fuzzy is necessary right now.
For STP on a 3550.
Root Bridge
If I have a two trunk links between sw1 and sw2 and I want a particular
bridge (in this case sw1) to be root
1) I could use the 'spanning-tree vlan x,y,z root primary command to make
the bridge root bridge for the vlans x,y,z.
2)I can also use the 'spanning-tree vlan x,y,z priority n' global command to
assign a value to influence the natural election process for the root
bridge.
Port Preference
I will assume that I have three ways to make a particular port prefered over
another.
1) interface command spanning-tree port-priority n to influence the natural
selection
2) interface command spanning-tree cost n to influence the natural selection
3) allow the tie-breaker to occur being lowest mac address for the
interface.
TIA,
Wayne
