Cisco White Paper on IPS 4500 & 4300 Series Sensors

Vendors are rarely believable when data sheets state the performance of IPS systems. That’s partly the fact that IPS performance is variable according to types of inspection rules that are configured and the amount of traffic hitting those rules, in use. In short, IPS performance is determined by the complexity of the rules you choose to […]

Big Vendor Head Shuffles at the SDN Curling Rink

Curling is a sport that involves people tossing a rock down an ice rink and then using brooms to guide it’s path. That’s a pretty apt description for employer changes in the SDN/OpenFlow space in the last few months. David Ward was leading the SDN portfolio at Juniper. Rumour has it that John Chambers saw […]

Cisco Value in vCider is All Programmable Networking

Cisco recently bought vCider. vCider gives Cisco tools for cloud bursting and a proven network driver to deliver overlay networks. It’s a significant boost to their Programmable Networks strategy and definitely an SDN play.

The vCider technology was architecturally similar to Nicira by building tunnels overlays in a network and, in my view, many people are incorrectly misinterpreting this as the core value on the acquisition.

I would posit that there are two aspects to vCider that Cisco is likely to extract value from. 1 – Network driver in Linux. 2 – Cloud burst networking

Rant: Cisco Licensing Webinar – Surely a New Low for Customers

Check this out. An entire webinar devoted to licensing of just a single product from Cisco. Obviously, Cisco licensing of UCM is now so complicated and involved  that there “Subject Matter Experts”  dedicated to handling your queries about licensing upgrades. Not the product itself mind you, or the great new features, or planning your migration process. […]

Nexus 1000, Imperva WAF Intentions, Platforms and Partnering

Cisco Nexus 1000 has been a platform since it was launched, at least, that’s what I’ve always thought. Lately, Cisco has talked extensively about vPath 2.0 offering a multiservice data plane (great podcast with Cisco on vPath 2.0 at Packet Pushers) for service delivery on VMware hypervisors. And sometime NX1K will likely be on Openvswitch […]

Official: Cisco Says The ACE is not dead. It’s just resting.

Spoke with a Cisco spokesperson regarding the ACE and what it’s future looks like. Here is the official statement:

Cisco ACE is not EOL or dead ? Needs 40 Million Volts

Steven Schuchart from Cisco Analyst Relations leaves a comment over at Nerd Twilight to let us know that the Cisco ACE isn’t dead. Presumably, it’s about to get “40 million volts through it” to prove it’s “not dead” Yup I understand that there has been a lot of confusion and difficulty regarding ACE in the […]

Response: EIGRP vs OSPF – Take 2

Over at the Cisco Blog in the Architect & DE discussions (where some serious content exists), Donne Savage writes about the perennial debate. “EIGRP vs OSPF” For example, most everyone would agree eigrp is “simple to deploy”, but detractors would argue that simplicity leads to sloppy designs and only though complexity can we force network […]

Restrictions on Multi-Context Enhancements for Cisco ASA Software Release 9.0 – Updated

Another sign that it’s time to stop buying service modules for Catalyst 6500. This is not the time for dedicated hardware appliances such as ACE or ASA Service Modules. Mulitcontext support for routing and VPN is not available on C6500 ASA Service Module.   Multi-Context Enhancements Enhances the current ASA Multicontext capability to include support for […]

Cisco Adaptive Security Appliance (ASA) Software Q&A – Cisco Systems

The Cisco ASA must have new product managers in place. Haven’t seen the Cisco ASA software gets a  dedicated place on Cisco’s web site before. Usually I have to go rattling around the product support pages to find out information about the latest release. For what’s it’s worth, Cisco ASA 9.0 has following major features […]

Musing: The Dim Future of Cisco ACE & WAAS

Tony Bourke draws attention to the Barrons report that Cisco is scaling the back the ACE : Though even if it were true, it wouldn’t necessarily mean Cisco has given up on ACE. It could signal that Cisco is no longer interested in selling the ACE30 service module, preferring instead the ACE 4710 appliance and/or gearing up […]

Rant: Cisco claims “We’re Listening” to Simplifying Cisco Software Licensing

If this is the best that Cisco can manage when they are “listening” we have a huge problem with Cisco licensing strategy. Glam it up all you like, but this isn’t helping. It’s just ignoring us.

Basics: Three Types of Cisco UCS Network Adapters

In the Cisco UCS servers, there are three classes or categories of Network Adapters for B-series and C-Server servers. I write this down because it’s pretty hard to find this summary anywhere is Cisco’s documentation and I keep having to tell people the difference. Now I can point them at this blog post.

Response: Distributed? Centralized? Both? – Cisco Blog on OnePK and SDN

In this blog post, Frank Brockners ( part of the Get Your Build On team) gives a detailed and interesting look into Cisco’s SDN strategy and, specifically, how Cisco see OnePK as fitting into the market. At the moment, the future of SDN in the market is unclear. There are obviously point solutions in the data centre as Nicira showed recently but in terms of the overall network market outside of that market SDN is very unclear. I review this article and attempt to summarise Cisco’s SDN position.

Response: Cisco Blog – What Comes Next with Cisco and the ONF?

Omar Sultan writes on the Cisco Data & Cloud blog ….. We continue to strongly support ONF and its efforts related to SDN and our support has and will continue to been demonstrated in tangible ways.  One of the elements of the Cisco ONE announcement is onePK, which is an enabling technology and one of the […]

Cisco NX-OS CLI Tip – Feature Enabled, License and CLI Syntax

When working on NX-OS it’s kind of annoying to attempt to use a feature that hasn’t been enabled and get an error message. Why not get an “not enabled” or “not licensed” error message ?

Cisco IOS CLI Regex: sh ip bgp in

Vitaly left a comment on a blog post with a clever IOS CLI Regex tip. I though I would pick that apart as an exercise.

OpenFlow doesn’t undermine Vendors even though it changes everything

Many people have attempted to prove that OpenFlow creates disintermediation of the hardware market dominated by Cisco, Juniper etc. In fact, it’s allow these vendors to bring the very best of their core values to Software Defined Networking.
