ConfigBytes: Nexus 6000/5600 Latency & Buffer Monitor

ConfigBytes: Nexus 6000/5600 Latency & Buffer Monitor

#CONFIGBYTES Episode 2 Platforms: Nexus 6000 & 5600 (UPC based ASIC)   Latency Monitor: Full Documentation The switch latency monitoring feature marks each ingress and egress packet with a timestamp value. To calculate the latency for each packet in the system the switch compares the ingress with the egress timestamp. The feature allows you to display historical latency averages between all pairs of ports, as well as real-time latency data. You can use the latency measurements to identify which flows…

Cisco Smart Install

Cisco Smart Install

This is my first post in a new series called “Config Bytes”. My objective is simple. Take a technology that I’m working on with a customer and post the data points. Overview: A global company asked me if there was an easy way to provision switches for rapid deployment. They are somewhat limited on networking personal and this would save the team some time if they could automate the staging of switches before deployment . The basic requirements were a standardized…

Cisco Modeling Labs 1.0: First Impressions & Getting Started

Cisco Modeling Labs 1.0: First Impressions & Getting Started

When a Legend becomes Real I’m still pinching myself. Last week I delivered my very first Cisco Modeling Labs (CML) 1.0 demo to a customer. Overall, they were pretty darn excited, however there are some things that we need to address to make it a GREAT fit for their specific testing/validation environment. Let’s take a step back and talk high level about CML for a moment. CML is the Cisco TAC supported variant of VIRL. The FCS date for CML 1.0…

Next Wave of UCS Innovation

Next Wave of UCS Innovation

Today was a BIG day for us at Cisco. We announced our next wave of UCS products and continue building our data center innovation superhighway. Did we announce one product? NO! We announced four major UCS products today at #UCSGRANDSLAM and it was AWESOME! I knew about this stuff for months, but had to keep quite. As you can imagine, I was at the point of imploding because I just wanted to share this info with EVERYONE. Here is a quick…

“It’s gonna take time, a whole lot of precious time, it’s going to take patience and time to do it right child.” “It’s gonna take money, a whole lot of spending money, it’s going to take plenty of money, to do it right” -George Harrison Song: I got my mind set on you  I’m pretty sure George had something else on his mind and NOT the CCIE when he wrote that song. I can tell you no other lyrics resonate…

CCIE Studies: Performance Routing PfR/OER

CCIE Studies: Performance Routing PfR/OER

Prologue Hey fellow CCIE’s candidates and networking geeks. Today I want to step deep into the realm of PfR or Performance Routing. First let’s go back in time to the predecessor, Optimized Edge Routing or OER. As crazy as this sounds, OER came out in 2006 with IOS 12.3 . So, technically before all this SDN fanfare, Cisco actually decoupled the control (part of it at least) and data plane with OER/PfR back in the dizay. DID THAT JUST BLOW…

Cisco UCS: Virtual Interface Cards & VM-FEX

Cisco UCS: Virtual Interface Cards & VM-FEX

Hello once again! Today I decided to talk about some Cisco innovations around of UCS platform. I’m going to try my best to keep this post high-level and EASY to understand as most things “virtual” can get fairly complex. First up is Virtual Interface Card (VIC). This is Cisco’s answer to 1:1 mapped blade mezzanine cards in blade servers and other “virtual connectivity” mezzanine solutions. Instead of having a single MEZZ/NIC mapped to a specific internal/external switch/interconnect we developed a vNIC optimized for virtualized…

Cisco: Algo Boost Nexus 3548 Preview/Unbox

Cisco: Algo Boost Nexus 3548 Preview/Unbox

I got something very cool last week. It came overnight from my good friend Frank in NY. What we have here is a very special privilege folks. It’s a prototype of the Nexus 3548 ultra low latency switch using our custom ASIC called Algo Boost/Monticello. Instead of killing you with all the details I decided to create a video of the un-boxing and special features walkthrough. Enjoy! https://www.youtube.com/user/4g1vn/featured
