Force SW1 to be the STP root

SW1 and SW2 both default to STP priority 32768. Lowest MAC wins the tie — which in production is unpredictable. Configure SW1 so it wins the root bridge election for VLAN 1 deterministically.

Topology

Objectives

○SW1 STP priority for VLAN 1 is lower than 32768
○SW1 wins root election for VLAN 1

Hints

Hint 1 — two ways

Either spanning-tree vlan 1 priority 4096 (explicit) or spanning-tree vlan 1 root primary (macro — sets 24576). Priorities MUST be multiples of 4096.

Hint 2 — full sequence

enable
configure terminal
 spanning-tree vlan 1 priority 4096
