Since in this case the interface number is Gigabit0/1, so the Port-Priority will become 128.1. But you can lower it if you want to do some traffic engineering. For example:
WebThe root bridge has a path cost of 0. When the BPDU is received on the downstream switch's root port, the local port cost is added (0 + 4 = 4). The sent BPDU has a path cost of 4. This process continues so that SW3 has a cost of 8, and SW4 has a cost of 12. These values are based on the default port cost of 4 for a 1 Gbps interface.

WebMay 15, 2006 · Right now, on switch ports for instance, we already allocated 4 bits to the port number (which is now 12 bits) and the configurable priority is by increments of 16 (because 4 bits were removed). If we had to support more than 4k ports, we would have to reduce even further the number of bits left for the priority. Regards, Francois
WebEach port of a Switch has a Spanning Tree Port Priority value associated with it, which is equal to 128 by default. We can view the spanning-tree command by using show command "show spanning-tree". The priority values are 0, 32, 64, 96, 128, 160, 192, and 224.
