2000-A2-GB20-10 - 124 - February 2004Configur-ing Span-ning TreeBridge Pri-orityThe Spanning Tree algorithm selects the bridge with the lowest priority onthe network as the Root Bridge.To set the Spanning Tree bridge priority (a value between 1 and 65,565—default 32,768), follow these steps:1. Type R on the Bridge Configuration menu to select Configure SpanningTree Bridge Priority.The IAD displays the following instructions:Enter Bridge Priority (1..65535): (32768)Type the priority and press Enter.2. The IAD updates the configuration.3. Press any key to display the Bridge Configuration menu.4. Continue with other configuration tasks.5. Reset the IAD (page 14) when you finish bridge configuration.Configur-ing Span-ning TreePort Prior-ityThe spanning tree algorithm uses the spanning tree bridge priority todetermine which bridge to use as the Ethernet LAN destination when twoor more bridges are bridging between the same LAN.To set the Spanning Tree priority by port (range 0 - 255—default 128),follow these steps (the lower the value, the higher the priority):1. On the Bridge Configuration menu, type Q to select ConfigureSpanning Tree Port Priority.2. The IAD displays the interfaces available on this IAD, and a prompt.Available Interfaces:1. G2237 xDSL2. 10/100BaseT Ethernet0. (Abort)Type the number of the port for which you want to set the priority.3. If more than one interface is configured on the selected port, the IADdisplays a list of interfaces:Port DLCI Encapsulation1 18 Proprietary Voice DLCIType the number of the port.4. The IAD displays a prompt:Enter Priority for Slot 2, Port 1 (0..255):Type the priority value and press Enter.5. The IAD updates the configuration and displays the BridgeConfiguration menu.6. Repeat these steps for each port on which you want to set the priority.7. Continue with other configuration tasks, or press Escape to return tothe Bridge Configuration menu.8. Reset the IAD (page 14) when you finish bridge configuration.
