PortFast (edge port) bypasses the listening and learning states so an end-host interface reaches forwarding without the normal 30-second STP delay. Th
What Prevents a Workstation from Receiving a DHCP Address?
Spanning Tree Protocol (STP) can prevent a workstation from receiving a DHCP address if PortFast is not enabled on the access port. This page establis
Rapid PVST+ Port State That Neither Receives BPDUs nor Learns MAC
In STP/PVST+, a Blocking (or Discarding) port still receives and processes BPDUs to track topology. A Disabled port is administratively shut down: it
Electing the Root Bridge by Lowest Priority Then MAC
STP elects the root by lowest bridge priority, then lowest MAC. In the exhibit SW2 and SW3 share the lowest priority (8192), lower than SW1/SW4's defa
Electing the Root Bridge in PVST+ by Priority and MAC
STP/PVST+ elects the root bridge by the lowest bridge priority, then by the lowest MAC address as a tiebreaker. SW3 and SW4 share priority 8192 (lower
Root Bridge Election on a Priority Tie: Lowest MAC Wins (SW2)
STP elects the root by lowest bridge priority first. SW2 and SW3 are tied at priority 4096, so the tiebreaker is the lowest MAC address, and SW2's MAC
Electing the Root Bridge by Lowest Priority (SW2)
STP elects the root by lowest bridge priority first. SW2's priority is 4096, lower than the other switches' priorities, so it becomes root without nee
Root Bridge Election by Lowest MAC When Priorities Are Equal (SW4)
With identical bridge priorities across the switches, STP elects the root by the lowest MAC address. SW4's MAC (0C:0A:05:22:05:97) is the lowest of th
