Inter-VLAN Routing on the Nexus 5k.

Nexus-PLineI previously had the chance to play around with the 5596UP switch, and made some notes on how to configure inter-vlan routing. Since this was a 5596UP switch I needed a layer 3 card to take advantage of it. The next-generation units the 5600 include layer 3 without a card required along with introducing 40GB uplinks! However in this post let’s go back to the basics and configure inter-vlan routing on a nexus switch and in this case I am using a 5596UP.  Continue reading

640-911 (Chapter 4)

Continuing where we left off on Chapter 3 on CCNA Data Center Study Guide from Todd Lammle. Like before feel free to post questions below. In these post I am only going over the topics of each chapter of the book, plus any examples the book offers and to get an idea of what the Cisco exam would cover. In chapter three we discussed about Ethernet Technologies and in chapter four we will learn about the TCP/IP protocol which is fundamentally the protocol that makes the Internet work.

Connecting FEX (5k to 2k)

Nexus-PLineI was pretty excited to get my hands on some of the Cisco Nexus product line which focuses on switching in the data center. The gear I have is an evaluation unit so I made some notes and one thing I was impressed is how easy it is to connect a Nexus 5K to a Nexus 2k also known as a fabric extender. I have kept it simple as the gear I have is a single Nexus 5596 along with a single Nexus 224TP-E who needs redundancy right? So in this post I’ll explain how to connect a 5k Nexus to a 2k extender. Let’s get started! Continue reading

CCNA 2.0 What’s New?

Cisco-NetworkI brought this topic up in March of this year (See original post) but I wanted to re-post it to add some information because as of today this was your last day to pass the older CCNA exams. Cisco has a refreshed all the CCNA Routing and Switching exams. That includes the ICND1 (640-822), the ICND2 (640-816), and the all in wonder exam (640-816). You will notice some old references no longer mentioned on this refresh, so let’s go over the differences and some of the changes Cisco has made to the associate-level certification track.
