Sunfire B1600 manual Spanning-tree pathcost method, Consoleconfig#spanning-tree priority

Command Usage

Bridge priority is used in selecting the root device, root port, and designated port. The device with the highest priority becomes the STA root device (0=highest, 61440=lowest). However, if all devices have the same priority, the device with the lowest MAC address will then become the root device.

Example

Console(config)#spanning-tree priority 40000

Console(config)#

Command Usage

The path cost method is used to determine the best path between devices. Therefore, lower values should be assigned to ports attached to faster media, and higher values assigned to ports with slower media. Note that path cost (page 4- 112) takes precedence over port priority (page 4-114).
