F5 Network’s Traffic Management Operating System (TMOS) is, first and foremost and for the sake of clarity, NOT an individual operating system. It is the software foundation for all of F5’s network or traffic (not data) products; physical or virtual. TMOS almost seems to be a concept rather than a concrete thing when you first try […]

EIGRP is a distance vector routing protocol that for many years was unique to Cisco networking environments. Created and championed by Cisco, it didn’t get any traction in the standards bodies in the early days, because there were already enough interior gateway routing protocols around according to some. EIGRP just didn’t interest enough of the […]

Quick notes on the “inactive” port status seen on the Cisco Nexus platform, which was perplexing the first time I ran into it. This isn’t a new status, existing on a variety of Cisco platforms for a long time now. As it happens, I’ve just not seen it that often historically. In dealing with the […]

In my continuing series on the decidedly boring, I would like to discuss the subtle, yet paralyzing, evil of stale documentation. In my experience, stale documentation can be useful or it can be disastrous, depending on how much is wrong. Personally, when I see more than a couple of tiny mistakes in a diagram, spreadsheet, […]

Because of my personal interest in the CCIE Security program (at least the written exam the next time I’m up for CCIE recert), I asked Nat Timms if there was an updated CCIE reading list. This list was recommended to me by Nat in her role as CCIE Security program manager; a big thanks to […]

On March 26, 2013, the Packet Pushers held a sponsored webinar with Anuta Networks to introduce their nCloudX controller to our networking community. In the webinar, the Anuta team covers the following: A bit about their background, the problems they are going after, and how nCloudX addresseses these challenges. An explanation of the nCloudX architecture, […]

Is this you perhaps? You’re the king of the network. You know it all inside out (your company and its processes too). You have every CLI mastered, you know the RPs you use in-depth, you’ve seen and used all the big management platforms, and you even know a fair bit about a few critical applications. […]

I recently completed a challenging upgrade on a pair of production F5 3600s running 10.2.0, going to 11.2.1 running the LTM module. In hindsight, it shouldn’t have been a challenging upgrade, but that was due to the things I learned along the way. Lessons Learned License reactivation. The upgrade document doesn’t say much about this. […]

Software Defined Networking (SDN) is revolutionizing the traditional networking approaches that have become too complex, closed, proprietary and/or difficult to program. The technology has the potential to enable network innovation by allowing network owners and operators more control of their infrastructure, thus allowing customization, optimization, and the reduction in overall capital and operational expenses. SDN […]

This article is meant to serve in part as an appendix to my previous post on PacketPushers.net. Therefore, please take a moment to read this introduction of Sakura Internet’s DDoS detection and mitigation app if you haven’t already. At Sakura, we are in the process of implementing source-and-destination-based DDoS packet filtering that should be effective and […]

Unlike some others in the network industry (until lately at least), those dealing with F5 Networks’ products are probably well accustomed to change – significant and fast paced change at that. F5 are not a company to shy away from rapid change and replacing old technology and tools with newer, better ones. The change from the […]

SDN innovation has been primarily focused on the data center where centralized network programmability has been shown to be capable of providing many benefits to the complex and dynamic (on-demand) data center environment. Service provider networks will also benefit from SDN. Traversing a service provider network involves crossing different network types, technologies, layers and administrative domains. SDN solutions, including OpenFlow’s programmatic control, will provide capabilities unique to these service provider technologies. Huawei presents an architecture that expands SDN into multiple, task specific, controllers and domains and extends networking control across all of the service provider network dimensions.

As I do most days, I took a walk in the woods at the back of my garden after a hearty dinner. I was quite surprised to come across a small wooden yellow door I’d never seen before, set into the trunk of a tree I’d never noticed until today. I opened the door and squeezed […]

Network engineers deal with technical support frequently. That’s the nature of the networking business: the products often don’t work as advertised or break down under their own complexity. Throw in some ambiguous documentation that leaves you scratching your head, and you’ll finally resort to opening a case with the vendor to resolve the issue. In […]
