Today at Cisco Live we started to show a train model that we use as a testing/validation vehicle for applicable train technologies.
At Cisco Live, the train includes our Cisco IE2000 industrial switches (IP67 and non IP67 versions), Cisco-819 M2M router, our target application hosting server-PC with VSMS and an even smaller application hosting server – a Raspberry PI.
Every car also hosts our ruggedized Cisco-IPVSC-6050 cameras and a demo version of a passenger information system (PIS) with both outside-train LCD and top-of-seat LCD panels. This is built on a Arduino/Linux prototype platform. Cameras and PIS-devices are PoE powered from our switches. Read More »

It’s that time of year again—the Cisco IOS Software Security Advisory Bundled Publication will go live in seven days. As a reminder, the Cisco Product Security Incident Response Team (PSIRT) releases bundles of Cisco IOS Software Security Advisories on the fourth Wednesday of March and September each calendar year. As is the case with the vast majority of our advisories, vulnerabilities scheduled for disclosure in these upcoming Security Advisories will normally have a Common Vulnerability Scoring System (CVSS) Base Score from 7.0 to 10.0.
To ensure you’re prepared for the upcoming publication, consider:
- Creating a text file of all the Cisco IOS Software releases in your network
- Assembling a simple list of Cisco IOS Software technologies and features you use
- Noting your Cisco.com username and password
- Locating the username and password for your Cisco IOS routers and switches
- Ensuring network operation partners are prepared for the security advisory release
- Reviewing the benefits of OVAL and CVRF content

In the previous installment of the onePK series, you received a crash course on Cisco’s onePK. In this article, you’ll take the next step with a fun little exposé on onePK’s C API. You will learn how to write a simple program to reach out and connect to a network element. This is staple onePK functionality and is the foundation upon which most onePK applications are built.
The following short program “ophw” (onePK Hello World), is a fully functional onePK application that will connect to a network element, query its system description, and then disconnect. It doesn’t do anything beyond that, but it does highlight some lynchpin onePK code: network element connection and session handle instantiation. This is the foundational stuff every onePK application needs before useful work can get done. Read More »

With the introduction of Cisco mDNS Service Discovery Gateway in IOS, customers that have implemented the solution are observing client behavior they haven’t seen prior to extending services across subnet boundaries. One of the effects is the duplicate name issue seen when devices with enabled services are moved from one L3 subnet to another L3 subnet and these two subnets happen to be connected to the same router/switch running the Service Discovery Gateway (SDG).
When devices (like a Mac OS X computer) offer a service such as Remote Login (SSH) or Screen Sharing (VNC), they will announce these services using mDNS/Bonjour/Zeroconf using their hostname as configured in ‘System Preferences -> Sharing -> Computer Name’ (see Fig. 1).

Cisco’s One Platform Kit (onePK) is a fantastic toolkit for building custom applications that interact with your Cisco routers and switches. Using onePK, you can build automation directly into the network and extend all sorts of functionality using Cisco devices. The first in a three-part blog series, this article will introduce onePK to the reader, explain what it is, how it can be useful, and will show how to configure onePK on a router. The second and third installments will walk the reader through a simple security-relevant application using the C API. Important to note is that we’ll be covering the 0.6.0 version of onePK features and service sets. At the time of this writing, the toolkit is still in Controlled Availability and as such, is still in active development, and the API could change before it is released into General Availability. However, even in the face of API evolutionism, this article will provide you with a solid jumping-off point for your plunge into the wondrous world of onePK.
OK, Just What is onePK?
OnePK is a Cisco IOS Software feature and a set of programming libraries enabling an application programmer to build powerful applications that tightly integrate and interact with Cisco devices. onePK is available to you via a well-documented and unified API, currently offered in C and Java with Python in active development. It is currently in pre-release and is available only on request. Details on how to obtain onePK are provided below. Read More »
