Solved: STP UplinkFast and BackboneFast
When Backbonefst is enabled, a switch detecting an inferior BPDU can infer that there has been a topology change and immediately start a process to find an alternative path to the root bridge.

Spanning Tree UplinkFast
UplinkFast increases spanning tree conversion time. This lesson explains what it is, how it works and how to configure it.
Understanding and Configuring the Cisco UplinkFast Feature
The UplinkFast feature dramatically decreases the convergence time of the STP in the event of the failure of an uplink on an access switch. UplinkFast interacts with other switches that have a strict
Spanning Tree Uplink Fast – routingloop
Educating Downstream Switches About the New Topology Having fast failover to a new physical topology is nice, but not all that useful if we must wait for the MAC aging timer to expire for
Port Fast Uplink Fast and Backbone Fast
UplinkFast optimizes convergence when an uplink fails on an access layer switch. For good STP design, access layer switches should not become root or become transit switches.
UplinkFast
The UplinkFast feature is designed to run in a switched environment when the switch has at least one alternate/backup root port (port in blocking state), that is why Cisco recommends that
Catalyst 4500 Series Software Configuration Guide, 7.5
You can disable only spanning tree UplinkFast processing on the switch using the set spantree uplinkfast disable command. This command does not affect the bridge priority, port cost, and port
uplinkfast
RSTP incorporates the enhancements provided by uplinkfast and backbonefast with its base operation. In case of uplinkfast, the switch tries to speed up convergence when multiple paths to the root bridge
Spanning Tree Uplink Fast – routingloop
Uplink Fast helps with this by allowing SW3 to switch to G0/1 almost immediately. Testing Without Nerd Knobs Before configuring Uplink Fast, we need to first observe STP status and

Understand and Configure Backbone Fast on Catalyst
By default, backbone fast is disabled. Backbone fast is not supported on Catalyst 2900XL and 3500XL switches. In general, you need to enable

Everything You Need to Know About Aggregation Switch
What is an Aggregation Switch and How Does it Work? An aggregation switch consolidates data traffic from multiple network access
Spanning Tree Uplink Fast – routingloop
The feature only needs to be enabled on edge switches that need to rapidly switch to a new root port. When Uplink Fast is configured, it is applied to all VLANs.
Layer 2 Configuration Guide, Cisco IOS XE 17.13.x (Catalyst 9200
This chapter describes how to configure the Multiple Spanning Tree Protocol (MSTP) on the Cisco Catalyst Switches.

Loop Guard, Uplink Fast, Backbone Fast and UDLD
In this lesson, we will learn other Spanning Tree Protocol Convergence Mechanisms; Loop Guard, Uplink Fast, Backbone Fast and UDLD. Now, let''s learn each of these switch mechanisms and their
Configuring Spanning Tree PortFast, BPDU Guard, BPDU Filter, UplinkFast
By default, spanning tree sends BPDUs from all ports regardless of whether PortFast is enabled. BDPU filtering is on a per-switch basis; after you enable BPDU filtering, it applies to all PortFast-enabled

STP Uplinkfast | NetworkAcademy.IO
The UplinkFast feature is designed for access layer switches—those at the edges of the spanning tree. It allows these switches to quickly switch to a backup uplink if the main (root port) uplink goes down, as
