#ConfigBytes Updated 02.17.2017 Full PDF: Cisco Nexus 9500 IO Module Matrix This is a work in progress, so if there are fields you’d like to see added, please tweet me @Cisco_East or post in the comments section below.
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…
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…
#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…
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…
#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…
CCIE Data Center Lab Blueprint 1.1c Implementing Port Channels ConfigBytes #2 Port Channels A port channel bundles physical links into a channel group to create a single logical link that provides the aggregate bandwidth of up to 16 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. F and M series line card port members cannot be mixed into…
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…
Only Perfect Practice Makes Perfect” -Vince Lombardi This is a quote that instantly comes to mind when I was thinking up a title for this post. You see, it’s been over 20 years since I started my journey of becoming a better sport shooter. What I never realized back then was just how difficult it was to be consistent and accurate. You see, I had this preconceived notion, that you point and shoot. “It’s easy!” Nothing could be further from the…
I am the Law! It’s that time of the year. The time we enjoy with our family, friends, and stuffing our faces with pie. This year left a painful scar on many gamers eager to play their 8th generation console on Christmas day. Both PSN and Xbox Live were hacked (DDoS) and taken offline. That means, no console updates, no digital downloads (sorry bundle owners) and no multiplayer. It’s come to the point where we need to institute a new law regarding…
