Catalyst 9300: Hands-On Review

Catalyst 9300: Hands-On Review

Cisco Catalyst 9300 (First Impressions) I received an email from our awesome lobby ambassador about two packages that arrived in the Malvern office. I didn’t remember what I ordered and quickly forgot about the packages because, it was such a chaotic week. When I finally made my way to the office, I saw the boxes in the mail room and thought “NO! That can’t be them already…”. Upon closer inspection, they were in fact the Catalyst 9300’s I had ordered….

The Network. Intuitive.

The Network. Intuitive.

A New Network for a New Era Well, the cat is finally out the bag… I’ve been biting my lips for the last several months working on campus designs with customers. That’s because internally at Cisco, all the buzz was around bringing SDN and most importantly intent driven networking to the campus in a BIG way. This is very much akin to how Cisco transformed the data center with ACI. In fact, I’ve heard verbatim from customers “why doesn’t Cisco…

ConfigBytes: ASA 5506x w/ FirePOWER Services

#ConfigBytes Getting Started with the ASA5506x & FirePOWER Services   Official Quick Start Guide: http://www.cisco.com/c/en/us/td/docs/security/asa/quick_start/5506X/5506x-quick-start.html FirePOWER User Guide: http://www.cisco.com/c/en/us/td/docs/security/firesight/541/firepower-module-user-guide/asa-firepower-module-user-guide-v541.html FirePOWER Services for ASA Data Sheet: http://www.cisco.com/c/en/us/products/collateral/security/asa-5500-series-next-generation-firewalls/datasheet-c78-733916.html   TL:DR Key Points Since the ASA5506x doesn’t have built-in switch capabilities (yet), you will need a L2 switch to connect the management interface which is used for firepower services module and your inside ASA interface for management. If you have an L3 switch the FirePOWER management interface can be on a different subnet from your inside…

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 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…

CCIE R/S v5: Everything’s Gonna be Alright

CCIE R/S v5: Everything’s Gonna be Alright

It’s been roughly five months since I passed the v4 CCIE R/S and I’m starting to hear potential CCIE R/S candidates freaking out about the upcoming changes. I know this feeling all too well, because like many of you I started on v3 and passed on v4. I will never sugar coat this, it’s a royal pain in the arse when the blueprint gets revised, especially if you have been studying (really studying) the current blueprint. That being said, I…

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…

CCIE DNA: Reality or Myth?

CCIE DNA: Reality or Myth?

It all started at #CLUS Unfortunately, I was unable to attend Cisco Live US in Las Vegas this year. Don’t shed any tears for me as I was fortunate enough to have customers, friends, and co-workers attend. They got me some sweet swag and provided a play-by-play as things unfolded. One such morsel of information was regarding a “CCIE DNA” or “CCIE GUI”. At first I was just sitting in front of my monitor drifting into space thinking what the format of…

CCIE Data Center: Version 2.0

Woah… Deja Vu This all seems so familiar… OH YEA! I went through this once before already. I took the CCIE R/S version 3 with the high (naive) hopes of passing it my first attempt. #n00b The challenge I had with the R/S v4 update was that it felt like the content managers had a serious case of ADD. Open ended questions, no open ended questions, troubleshooting, etc… It was frustrating that I had to experience every possible derivative of the…

The Journey to CCIE #2 Starts Now

The Journey to CCIE #2 Starts Now

Game On Old Friend   It’s hard to believe that it’s been almost 2 years since I passed the R/S lab and my digits (40755) were assigned. I remember the numbers just passed 40k and I was so hoping to get 40007. This way I could be 007. <GRIN> Now I’m ready for the next challenge. My motivation for CCIE DC was simple. First I wanted to challenge myself yet again. Second, I feel strongly that a deep understanding of UCS…

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. F and M series line card port members cannot be mixed into…

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…
