SpletCD1 (config)#spanning-tree vlan 10 root primary. 2. If CD1 fails we need to ensure that the Spanning Tree Root Bridge will failover to CD2 rather than an access layer switch. CD2 (config)#spanning-tree vlan 10 root secondary. 3. Verify CD1 has the best Bridge Priority and becomes the Root Bridge. 4. SpletCreating the Spanning-Tree Topology . In Figure 11-1, Switch A is elected as the root switch because the switch priority of all the switches is set to the default (32768) and Switch A has the lowest MAC address.However, because of traffic patterns, number of forwarding interfaces, or link types, Switch A might not be the ideal root switch.

From the factory all switches have the same priority (step 8 of the 16 configurable steps) so the switch with the lowest MAC automatically get's selected as root. how to figure 30% margin
