When adjusting STP priority with the root command, what priority will the local switch have if others are set to default?

The Spanning Tree Protocol (STP) uses a bridge priority value to determine which switch becomes the root bridge in a network. By default, all switches in an STP-enabled network are assigned a bridge priority of 32,768. When you adjust the priority of a switch using the root command, you're setting a priority that will determine its eligibility as the root switch compared to others in the network.

If others are using the default priority of 32,768, and you want to set the priority of the local switch lower than the default (resulting in a higher likelihood of being elected as the root), lowering it to 24,576—which is 8,192 less than the default—makes it a valid choice. In this scenario, if the local switch is set to 24,576 while the others remain at their default of 32,768, this switch has a higher chance of becoming the root bridge because it has a lower priority number.

The selection of 24,576 aligns with the priority values available in increments of 4,096 (the increments specified by the IEEE 802.1D standard).
