What does N spanning tree port type network do?
What does N spanning tree port type network do?
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 port type edge trunk?
Spanning Tree Edge Ports Edge ports, which are connected to hosts, can be either an access port or a trunk port. The edge port interface immediately transitions to the forwarding state, without moving through the blocking or learning states.
What is port profile in Nexus?
Port profile is a mechanism used in NEXUS family of switches for simplifying the configuration of interfaces. We can assign a port profile to multiple interfaces and provide them all the same configuration. One can configure Ethernet or vEthernet port profiles to which Ethernet or vEthernet interfaces can be assigned.
What are the Spanning Tree port states?
STP Port States Blocking – When a device is connected, the port will first enter the blocking state. Listening -The switch will listen for and send BPDUs. Learning – The switch will receive a superior BPDU, will stop sending its own BPDUs, and will relay the superior BPDUs. Forwarding – The port is forwarding traffic.
What are the two key benefits of VLANs?
VLANs provide a number of advantages, such as ease of administration, confinement of broadcast domains, reduced broadcast traffic, and enforcement of security policies.
What is edge port mode?
Information. 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.
Can a spanning-tree have cycles?
All the possible spanning trees of a graph have the same number of edges and vertices. A spanning tree can never contain a cycle. Spanning tree is always minimally connected i.e. if we remove one edge from the spanning tree, it will become disconnected.
How do I enable ports on my Nexus?
You can make all ports Layer 2 ports using the setup script or by entering the system default switchport command. See the Cisco Nexus 9000 Series NX-OS Fundamentals Configuration Guide for information about using the setup script. To configure the port as a Layer 2 port using the CLI, use the switchport command.
How do I configure Nexus switch?
Power up the new Nexus switch and connect to the console port using a serial cable. The switch will take several minutes to boot. The initial configuration wizard starts automatically. Use the information you worked out with your team or with the customer to complete the wizard.
What is STP port cost?
The default port cost is defined by the speed at which the port operates. As shown in Table 3-1, 10 Gbps Ethernet ports have a port cost of 2, 1 Gbps Ethernet ports have a port cost of 4, 100 Mbps Fast Ethernet ports have a port cost of 19, and 10 Mbps Ethernet ports have a port cost of 100.
How many ports are there in Rstp?
three port states
RSTP defines three port states: discarding, learning, and forwarding and five port roles: root, designated, alternate, backup, and disabled. A RSTP capable switch determines what spanning tree will be computed by the algorithm, but the rules as written require knowledge of the entire network.
Which is the normal spanning tree port in Cisco Nexus 5000?
Note 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.
Which is spanning tree port type do you use?
It is recommended that switch-to-switch links are configured with the spanning-tree port type normal command. The one exception is the vPC peer-link which is recommended to configure with the spanning-tree port type network command.
How to configure Cisco Nexus 5000 series NX-OS?
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
Which is the root switch on Nexus 5000?
In order to troubleshoot an STP issue, it is critical to know which switch is currently the root. The command to show the STP root on a Nexus 5000 Series Switch is: Here are some other relevant commands:
