When deploying a spanning tree protocol, you are advised to enable TC protection and configure all interfaces connected to terminals as edge ports. These measures prevent state changes of some interfaces from causing flapping and re-convergence on the entire network

Although the root bridge of a spanning tree is usually and automatically calculated, you can also manually configure a root bridge or secondary root bridge. The following provides more details regarding configuring a root bridge or secondary root bridge:•Configuring a root bridge: A spanning tree can have only one effective root bridge. When two or more devices are specified as root bridges for a spanning tree, the device with the smallest MAC address is elected as the root bridge.
•Configuring a secondary root bridge: You can specify multiple secondary root bridges for each spanning tree. When the root bridge fails or is powered off, a secondary root bridge becomes the new root bridge. If a new root bridge is specified, the secondary root bridge will no longer be the root bridge. If there are multiple secondary root bridges, the one with the smallest MAC address becomes the root bridge of the spanning tree.
