Does Nexus 7k support Vxlan?
The Cisco Nexus 7×00 platforms support inter-VXLAN routing in hardware.
Can vPC be formed between 2 VDC on the same device?
vPC can be configured in multiple VDCs, but the configuration is entirely independent. In particular, each VDC for the Nexus 7000 Series switches requires its own vPC peer and keepalive links and cannot be shared among the VDCs. The maximum number of switches in a vPC domain is two.
What is vPC and VDC in Nexus?
Most Nexus-based data center designs today use the concept of Cisco® virtual device context (VDC), which allows the creation of separate control-plane domains in a single switch. From a forwarding perspective, vPC is deployed in the context of a VDC.
How do I create a vPC on 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.
Does Nexus 7k support ACI?
Though Nexus 7000 series doesn’t participate in ACI, however will function as interconnect devices, linking together multiple ACI setups.
What is the difference between Nexus 7k and 9k?
The Nexus 9000 supports Application Centric Infrastructure (ACI) in contrast to the Nexus 7000 switches. However, the Cisco Nexus 9000 switches do not support the VDCs (Virtual Device Context) technology like the Nexus 7000 and the Nexus 9000 Series doesn’t support storage protocols, in contrast to the Nexus 7000.
How many vPC domains can a switch have?
Hi! As for now, only One vPC domain is allowed per Switch.
What happens if vPC peer-link goes down?
Another scenario is where the keepalive link is down and then the vPC peer-link goes down. In such a case, there is a split brain and both vPC peers move into a primary peer role (primary stays primary, while the secondary moves into an operational primary role) and behave as independent switches.
How many VDC can be configured 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).
What is the difference between port channel and vPC?
Here you can see that Virtual Port channel (vPC) is configured using the interfaces of two switches. One of the key difference between the two technologies (port-channel and virtual port-channel ) is that port channels support both Layer 2 and Layer 3. vPC on the other hand only supports Layer 2.
What is the difference between VSS and vPC?
Correct, VSS is only for Catalyst series switches and vPC is for the Nexus switches which are mainly designed to be used in data centers. As for as connecting the Cisco to Dell and other vendors, you can use LACP for bundling multiple uplinks in one logical connection.
What is the difference between Nexus and Catalyst switches?
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.
Can Nexus switches be stacked?
I know Cisco Nexus switches don’t support VSS or StackWise stacking, just vPC. The idea is the same and to view the two switches as one from the downlink device’s perspective.
What happens if vPC peer link goes down?
How does STP work in vPC?
STP Behavior in vPC:
vPC system is created to avoid the STP blocked ports and hence provide the loop free layer -2 topology. In vPC STP provide the following function: Protect the Layer 2 network by detection and breaking any loops before vPC configuration. Provides the loop free path for non-vPC attached device.
What is VDC in Nexus 7k?
The Nexus 7000 NX-OS software supports Virtual Device Contexts (VDCs), VDC(s) allow the partitioning of a single physical Nexus 7000 device into multiple logical devices. This logical separation provides the following benefits: Administrative and management separation.
How does vPC work on Nexus?
vPC’s, or Virtual Port Channels, are a Cisco Nexus technology. They are used to connect layer-2 devices to two switches at once. This makes it possible to create a highly available environment in the data centre. If one switch fails, the other one continues to operate.
What is the use of vPC in Nexus?
A virtual PortChannel (vPC) allows links that are physically connected to two different Cisco Nexus™ 5000 Series devices to appear as a single PortChannel to a third device. The third device can be a Cisco Nexus 2000 Series Fabric Extender or a switch, server, or any other networking device.
How does vPC work in Nexus?
What is the advantage of Nexus switch?
Nexus 9000 Series Switches offer numerous benefits which include – high performance and density, power efficiency, low latency, advanced programmability, architectural flexibility, greater scalability, real-time visibility and telemetry etc.
What is difference between Catalyst and Nexus?
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.
How do I check my vPC configuration?
To verify vPCs using the CLI, perform one of these tasks:
- Purpose. Command.
- show running-config vpc. Checks the status of the vPCs.
- show vpc peer-keepalive. Verifies that the vPC peers have the identical type-1 parameters.
- show vpc consistency-parameters.
- show tech-support vpc.
- show port-channel summary.
What is VSS in Nexus?
VSS (Virtual Switching System)
Compared to the vPC feature of the Nexus, the unified control plane aspect of VSS mode allows for the full system capabilities to be used on a multi-chassis EtherChannel, so L3 EtherChannels, MPLS awareness, full QoS capabilities, and other features are usable across both of the systems.
Why do we use Nexus switches?
Nexus Switches provide a quick and dependable switching infrastructure aimed at giving users the high performance needed for the virtualized environment in next-generation data centers.
What is vPC configuration?
vPC (Virtual Port-Channel), also known as multichassis EtherChannel (MEC) is a feature on the Cisco Nexus switches that provides the ability to configure a Port-Channel across multiple switches (i.e. vPC peers). vPC is similar to Virtual Switch System (VSS) on the Catalyst 6500s.
