On a single switch, the port-channel compatibility parameters must be the same among all the port-channel members on the physical switch. A port channel is an aggregation of multiple physical interfaces that creates a logical interface. You can bundle up to 32 individual active links into a port channel to provide increased bandwidth and redundancy. Port channeling also load balances traffic across these physical interfaces.
The port channel stays operational as long as at least one physical interface within the port channel is operational. You can create a Layer 2 port channel by bundling compatible Layer 2 interfaces, or you can create Layer 3 port channels by bundling compatible Layer 3 interfaces.Cisco Nexus 9000 VXLAN Config without multicast L3 as OSPF: Beginner VTEP VNI NVE overlay
You cannot combine Layer 2 and Layer 3 interfaces in the same port channel. You can also change the port channel from Layer 3 to Layer 2. See the Configuring Layer 2 Interfaces chapter for information about creating Layer 2 interfaces. Any configuration changes that you apply to the port channel are applied to each member interface of that port channel.
After a Layer 2 port becomes part of a port channel, all switchport configurations must be done on the port channel; you can no longer apply switchport configurations to individual port-channel members. You cannot apply Layer 3 configurations to an individual port-channel member either; you must apply the configuration to the entire port channel.
You can use static port channels, with no associated aggregation protocol, for a simplified configuration.
When you use LACP, the link passes protocol packets. You cannot configure LACP on shared interfaces. A port channel bundles physical links into a channel group to create a single logical link that provides the aggregate bandwidth of up to 32 physical links. If a member port within a port channel fails, the traffic previously carried over the failed link switches to the remaining member ports within the port channel.
However, you can enable the LACP to use port channels more flexibly. Each port can be in only one port channel.
NX-OS 9000v Feature Support
You can create port channels directly by creating the port-channel interface, or you can create a channel group that acts to aggregate individual ports into a bundle.
When you associate an interface with a channel group, the software creates a matching port channel automatically if the port channel does not already exist. In this instance, the port channel assumes the Layer 2 or Layer 3 configuration of the first interface. You can also create the port channel first.Please suggest. There is Nexus Titan you can launch it through vmware its free very buggy though and then there is Cisco Virl but i have heard that it does not do layer 2 yetnot sure about SAN and MDS.

UWM provides a web-based interface for administrators and users alike, providing information on the sessions they run, their quotas and usage information.The Cisco Nexus v is a virtual platform that is designed to simulate the control plane aspects of a network element running Cisco Nexus software.
The Cisco Nexus v shares the same software image running on Cisco Nexus hardware platform although no specific hardware emulation is implemented. The Cisco Nexus v for the Cisco Nexus Series provides a useful tool to enable the devops model and rapidly test changes to the infrastructure or to infrastructure automation tools. This enables customers to validate configuration changes on a simulated network prior to applying them on a production network. Some users have also expressed interest in using the simulation system for feature test ,verification, and automation tooling development and test simulation prior to deployment.
This virtual platform provides these virtualization benefits in a cloud environment and you are not limited to the type of hardware as well as other resources. This virtual platform provides these virtualization benefits in a cloud environment and users is not limited to hardware as well as other resources.
The resources used by Cisco Nexus v are managed by the hypervisor, and can be shared among VMs. The amount of hardware resources that VM sever allocates to a specific VM, can be reallocated to another VM on the server. You can easily move a VM from one server to another, Thus, you can move the Cisco Nexus v from a server in one physical location to a server in another physical location without moving any hardware resources.
Users can change network connectivity and configuration in a matter of mins without any physical cabling.
The Cisco Nexus v features in this table have been verified to operate only with the Cisco devices mentioned in this document. If a networking or system feature is not identified as a supported feature in this document, it should be considered as unsupported despite that it may seem to work correctly. Unsupported features did not have any level of regression testing on Cisco Nexus v. It maintains its own MAC Table. The consistency checker has a hardware dependency and hence is not supported on Cisco Nexus v.
Low data plane performance.

Additional rate limiter is in place to limit the total amount of traffic received by Cisco Nexus v to 4M. Connectivity between the two ends of the interface link is simulated, hence it is important that you shut the interface in both the ends, followed by no shut at both the ends of the interface link.
Feature enablement in the Cisco Nexus v virtual platform is the same as Cisco Nexus hardware platform. However, not all commands are available for Cisco Nexus v, such as hardware data plane specific commands. Some of these commands exist in the command parse chain, but these commands might not display correct output information.
It is not possible for the virtual platform to verify all commands on Cisco Nexus v that exist for the Cisco Nexus hardware platform.
The following displays substitute commands:.Ravi Balakrishnan. All of this in less than three months since going live in August The appliance is a full-featured Cisco APIC controller software along with a simulated fabric infrastructure of leaf switches and spine switches in one physical server. If you wondered how it is going to help you, think of it as a self-contained environment with Cisco APIC instances with real production software. You can use it to quickly understand ACI features, exercise APIs, and initiate integration with third-party orchestration systems and applications.
If you are a developer or Cisco partner, this is an ideal way to develop and test your solution. If you are a customer, you can use this in your test lab to create profiles for your enterprise apps with your actual application delivery controllers and security devices. This belongs in any well-architected DevOps environment. The Cisco ACI Simulator enables you to simulate the Cisco ACI fabric, including the Cisco Nexus Series Switches supported in a leaf-and-spine topology, to take full advantage of an automated, policy-based, systems management approach.

Best Regards santanu.If a networking or system feature is not explicitly identified as a supported feature in this document, it should be considered as unsupported. For example, the following features can be enabled as such:. However not all commands are available on NX-OSv ; specifically, hardware data plane commands.
Even though some of these commands do exist in the CLI parser, these commands may not work as expected. It is impossible to verify all existing commands of the hardware platform work as designed on the virtual platform.
In some cases the expected physical platform command will not exist in the virtual platform. Make sure to review table 1. It requires the minimum resources as shown in the following link.

For More Information. This document examines the increased importance of automation and programmability capabilities in the network.
It explores the various trends in the data center that necessitate flexible control of the underlying infrastructure: from the emergence of modern self-service IT to increased use of continuous integration using development and operations DevOps models.
Data center strategy has become a critical part of business strategy overall. Today, more than ever, the ways and means of IT deployment can make the difference between an efficient, successful organization and an inefficient one.
That is because today IT applications and services support increasing numbers of business operations and create competitive differentiation in many industries. However, the resulting proliferation of applications and their underlying server, storage, and networking technologies is placing increasingly greater burdens on IT staff, demanding more from IT than ever before.
One of the major burdens is the management of this complex IT environment, with considerable staff time needed to configure, deploy, and manage application infrastructure. A recent IDC study shows just how heavy this burden has become.
IT decision makers report that approximately three-quarters Analysis of the maintenance portion reveals the following:. Concurrent with the challenges of adapting to these changes in the IT industry is the continued challenge for IT to do more with flat or decreasing budgets.
This confluence of factors has caused IT managers to become eager to identify and adopt new technologies and solutions that deliver efficiency for those maintenance activities that are consuming more than three-quarters of staff time.
The goal of IT managers is to deliver excellent maintenance service with less staff effort and increase the focus on deployment of new services for the organization.
This trend is the focal point of evolving data center strategy.
