What does spanning 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 port type edge trunk?

If you enter the spanning-tree port type edge trunk command, the port is configured as an edge port even in the access mode. spanning-tree port type normal—This command explicitly configures the port as a normal spanning tree port and the immediate transition to the forwarding state is not enabled.

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. Root guard is enabled with the interface command spanning-tree guard root.

What is bridge assurance in Nexus?

Spanning-tree Bridge Assurance is one of those STP features that help to prevent bridging loops in your network. When bridge assurance is enabled, BPDUs are sent on all interfaces of your switch, including blocked interfaces like the alternate or backup port. Bridge assurance is only supported by PVRST+ and MST.

How do I disable spanning tree on Cisco Nexus?

The spanning tree feature cannot be turned off in switches on a per port basis. Although it is not recommended, you can turn off Spanning Tree Protocol (STP) on a per-VLAN basis, or globally on the switch. Use the no spanning-tree vlan vlan-id command in order to disable STP on a per virtual LAN (VLAN) basis.

What are the spanning tree port states?

There are five Spanning Tree Port States :

• Blocking State : Switch port enters the blocking state at time of election process, when a switch receives a BPDU on a port that indicates a better path to the Root Switch or if a port is not a Root Port.
• Listening State :
• Learning State :
• Forwarding State :
• Disabled State :

What is edge port?

A port is considered as an edge port when it is directly connected to the user terminal or server, instead of any other switches or shared network segments. The edge port will not cause a loop upon network topology changes.

What is edge port Cisco?

An RSTP edge port is a switch port that is never intended to be connected to another switch device. It immediately transitions to the forwarding state when enabled. The Cisco RSTP implementation, Rapid PVST+, maintains the PortFast keyword, using the spanning-tree portfast command for edge port configuration.

How can STP attacks be prevented?

There are two main protection mechanism against attack on STP process, Protecting with Root Guard and Layer 2 Protecting with BPDU Guard. Let’s see how is that working… The Root Guard can be enabled on all switch ports that should not become root ports. So that means on every port that is not a root port.

Should I enable spanning tree?

Broadcast storms caused by loops can slow or stop traffic on your network, but STP can prevent loops by ensuring that only one path between each set of switches is active. You must enable or disable STP or RSTP for each network location in which you are using Insight Managed Switches. By default, STP is disabled.

What is Spanning Tree Bridge?

The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.

What is Spanning Tree link type shared?

If the link comes up in half-duplex, the STP link type defaults to ‘shared’. The rapid transition of a Designated Port to Forwarding depends on the Port being directly connected to at most one other Bridge [it is an Edge Port (17.3, 17.19. 17), or is attached to a point-to-point LAN, rather than a shared medium].

How many VLANs does the Cisco Nexus 5000 support?

Even if the Cisco Nexus 5000 Series supports 505 VLANs, you can configure an MST region for the full range of more than 4000 VLANs previously listed. VLAN Ranges and MST Regions

How to configure spanning tree port types globally?

Configuring Spanning Tree Port Types Globally Command Purpose Step 1 switch# configure terminal Enters configuration mode. Step 2 switch (config)# spanning-tree port type Configures all interfaces as edge ports. Step 2 switch (config)# spanning-tree port type Configures all interfaces as spanning tr

How to find the root bridge of a spanning-tree VLAN?

If you do show spanning-tree VLAN A from the access layer, you see that the root bridge is Agg1. If you type the same command for VLAN E on the same switch, you see that the root bridge is Agg2.

Is STP necesary configure in the interfaces VLANs spanning-tree?

Its necesary configure in the interfaces vlans spanning-tree? Or in what cases must we configure spanning-tree in the interfaces vlans? 11-13-2015 06:46 AM 11-13-2015 06:46 AM In a best case scenario all hosts will use vPC, so STP would not be required, but, as per Cisco best practice, STP should be always enabled in case of misconfiguration, etc.
