These days I am seeing more and more Organizations are moving towards Nexus Switches for their Core and Server farm. Since Nexus Switches are pretty new and they work with NX-OS.  NX-OS is different from IOS, in this article I will try to highlight on some of the key differences between NX-OS and IOS.

We are familiar with the traditional Cisco IOS command line interface (CLI); the CLI interface of NX-OS is pretty similar to Cisco IOS.

One of the key differences I have noted is NX-OS is when you first log into NX-OS, you go directly into EXEC ode.

NX-OS features are based on license model, where as in IOS what matter was the type of IOS you installed. A good beginning from Cisco as you can install the required features, more over you can try a 120 day license grace period for testing.  After 120 days of testing the features will be automatically removed. This is some thing you never experienced in Cisco IOS.

Cisco NX-OS has the capability to either enable or disable the features OSPF, BGP, etc. by using the feature configuration command.

I will try to come up with some more details in the upcoming post.

Since we all know Cisco Systems has introduced Nexus Switches and NeXt-generation Operating System (NX-OS). I was wondering how  am  I going to configure them in our expansion project? As we are expected to have Nexus 7000, Nexus 5000 and Nexus 2000 Series Switches.

 

Thanks to Cisco Press soon they are releasing a title NX-OS and Cisco Nexus Switching which addresses the operation, use and configuration of the NeXt-generation Operating System (NX-OS) for Cisco data center products.

Currently the rough-cut pages of the title NX-OS and Cisco Nexus Switching are available. I just had a glance of some sample pages for some chapters.  The new title NX-OS and Cisco Nexus Switching has seven chapters

 

Chapter1: Introduction to Cisco NX-OS

Chapter 2: Layer 2 Support and Configurations

Chapter 3: Layer 3 Support and Configurations

Chapter 4: Multicast Configuration

Chapter 5: Security

Chapter 6: High Availability

Chapter 7: Serviceability

Chapter 1 deals with an Introduction to Cisco NX-OS and I liked the way sections covered in this chapter. The author starts with an overview of NX-OS and its advantages, some of the advantages of NX-OS are

 

Unified data center operating system

Robust and rich feature set with a variety of Cisco innovations

Flexibility and scalability

Modularity

Virtualization

Resiliency

IPv4 and IPv6 IP routing and multicast features

Comprehensive security, availability, serviceability, and management features

Currently the NX-OS platform is supported by following platforms

Nexus 7000

Nexus 5000

Nexus 2000

Nexus 1000V

Cisco MDS 9000

Cisco Unified Communications Manager (UCS)

Nexus 4000

 

Overall this title seems to very interesting and useful for the Network Administrators who are exploring their skills in the world of NX-OS. Eagerly waiting for Cisco Press to release this title in book format until then keep enjoying the rough cuts.

Cisco officially launched Nexus 5000 in this part of the region. There were some good presentations and case studies on Nexus 5000.Well the intresting part was some of the partners presentations. Among them Panduit came up with some great products which I would like to share with you all.Panduit designed an exclusive 45 U cabinet exclusively for the Nexus 7000 series Switch. This cabinet kit enhances interoperability, reduces installation time and supports the performance need s of Data Center. More details can be access from their website ttp://www.panduit.com/Products/ProductOverviews/ProductSearch/index.htm?Ne=1&N=5000001%201473%203004292&lastNodeId=ss_prod_cabinetsrackscables&R=CN1&sid=11AD24324688.
One more interesting thing Panduit came up is the fiber runner. This offers complete fiber cable routing solution to Data centers, it’s modular and can be installed in few minutes. It’s easy to manage and install. Do have a look at this video
