What is Bridge assurance in Nexus?
–> 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 is a nexus module?
Fabric Modules are like backplane of nexus Switches, when all the Line cards, Supervisor are inserted to nexus Chassis, then all line cards and supervisor modules are connected to each other via fabric Module. Traffic between Ingress and egress line card must pass through Fabric modules.
What is Supervisor module in Nexus?
The Cisco Nexus 7000 Supervisor Module is designed to deliver scalable control plane and management functions for the Cisco Nexus 7000 Series chassis. It is based on a dual core processor that scales the control plane by harnessing the flexibility and power of the dual cores.
How many VDC we can create in Nexus?
The maximum number of VDCs that can be configured per Nexus 7000 chassis is four; the default VDC (VDC 1) and three additional VDC(s).
Which option describes a design benefit of bridge assurance?
Which option describes a design benefit of Bridge Assurance? Options: A. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.
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.
Is Nexus owned by Cisco?
The Cisco Nexus series switches are modular and fixed port network switches designed for the data center. Cisco Systems introduced the Nexus Series of switches on January 28, 2008.
What is Nexus 7k?
The Cisco Nexus 7000 Series is a modular data center-class switching system designed for 10 Gigabit Ethernet networks. The Cisco Nexus architecture scales beyond 15 terabits per second. This platform is designed for exceptional scalability, continuous systems operation, and transport flexibility.
What is a supervisor module?
The supervisor module is the module that is the brains behind the whole switching operations. Its usually found in chassis based switches, nowadays, it handles everything, including routing and switching (older models had them separated.)
In which redundancy mode switch modules will be reloaded before the standby router initialize the supervisor functions?
You can use the following redundancy modes on Catalyst switches: Route Processor Redundancy (RPR)—The redundant supervisor is only partially booted and initialized. When the active module fails, the standby module must reload every other module in the switch and then initialize all the supervisor functions.
How do I add VDC to my Nexus 7k?
Nexus 7k – Getting Started Examples – Part1 (basics, VDC and vPC)
- Step 1 activate vpc feature.
- Step 2 Create VRF “vpc” and create an L3 keepalive link between the two Nexus switches.
- Step 3 Configure a vPC Peer Link.
- Step 4 Configure interface VLAN on all lab switches for VLAN 10 and VLAN 20.
What is the difference between Nexus and Catalyst switches?
Amongst the array of switches are the Cisco Nexus and Catalyst switches that are the most popular. While Nexus switches are a flexible and feature-rich solution that offers ease of integration and usage, the Catalyst switches allow better control over the throughput traffic.
Where can bridge assurance be enabled?
Also, Bridge Assurance can be enabled only on spanning tree network ports that are point-to-point links. Finally, both ends of the link must have Bridge Assurance enabled.
What ports does bridge assurance block?
If you enable Bridge Assurance, it automatically runs on network ports. By default, spanning tree ports are normal port types. If you configure interfaces connected to Layer 2 hosts as network ports, those ports automatically move into the blocking state.
Can bridge assurance run on a spanning tree port type normal?
If you enable Bridge Assurance globally, it automatically runs on a spanning tree network port. spanning-tree port type normal —This command explicitly configures the port as a normal spanning tree port and Bridge Assurance cannot run on this interface.
