When bridge Assurance is enabled on a port and we do not receive BPDU on that port?

2) “If a Bridge Assurance-enabled network port does not receive any BPDU for a configurable period of time, the interface moves into the blocking state.

When bridge Assurance is enabled on a port?

When bridge assurance is enabled, BPDUs are sent on all interfaces of your switch, including blocked interfaces like the alternate or backup port. When an interface doesn’t receive a BPDU for a certain time, the interface goes into the blocking state.

What is bridge assurance?

–> Bridge Assurance is one of the STP features that is used to avoid switching loops in your network. –> When bridge assurance is configured on the switch then BPDUs are sent on all interfaces of the switch, including blocked interfaces like the alternate or backup port.

What does Nspanning tree port type network do?

spanning-tree port type (default global) Configures all switch interfaces as edge/network/normal ports. These ports can be connected to any type of device. The no form of the command disables the spanning tree operation.

What is Spanning Tree Rootguard?

Root guard is an STP feature that is enabled on a port-by-port basis; it prevents a configured port from becoming a root port. Root guard prevents a downstream switch (often misconfigured or rogue) from becoming a root bridge in a topology.

How do I disable Bpdu guard?

To disable BPDU guard, use the no spanning-tree portfast bpduguard default global configuration command. You can override the setting of the no spanning-tree portfast bpduguard default global configuration command by using the spanning-tree bpduguard enable interface configuration command on an STP port.

What is STP dispute?

STP dispute is a mechanism that checks if the BPDUs that it receives on an interface match with the port role/state of the interface. This helps to detect unidirectional link failures and prevent bridging loops.

What is Spanning Tree port edge?

Interfaces configured as spanning tree edge ports immediately transition to the forwarding state, without passing through the blocking or learning states, on linkup. This command has four states: spanning-tree port type edge—This command explicitly enables edge behavior on the access port.

What is spanning tree Bpdufilter enable?

The STP BPDU filter feature allows control of spanning tree participation on a per-port basis. It can be used to exclude specific ports from becoming part of spanning tree operations. A port with the BPDU filter enabled will ignore incoming BPDU packets and stay locked in the spanning tree forwarding state.

What is spanning tree Rootguard?

Where should Rootguard be enabled?

Root guard is enabled with the interface command spanning-tree guard root. Root guard is placed on designated ports toward other switches that should never become root bridges. In the sample topology shown in Figure 3-1, root guard should be placed on SW2’s Gi1/0/4 port toward SW4 and on SW3’s Gi1/0/5 port toward SW5.
