Pardon me while I rant. This week, the world seems to have gone a little more insane. I’ve upgraded to Win10 over the weekend — after figuring out how to get my Wacom pad to work in some sort of reasonable manner (the Wacom drivers don’t really like the touchscreen drivers that don’t really like […]

I am currently studying for the CCDE exam. Elaine Lopes is the program manager for the CCDE and CCAr certification. I’ve had the pleasure of interacting with her online and meeting her at Cisco Live as well. The CCDE is a great certification and I wanted you to get some insight into the program and ask about the future of the CCDE. A big thanks to Elaine and Cisco for agreeing to do the interview.
Daniel: Hi Elaine, and welcome. It was nice seeing you at Cisco Live! Can you please give a brief introduction of yourself to the readers?
Elaine: Hi, it was nice to see you, too! My name is Elaine Lopes and I’m the CCDE and CCAr Certification Program Manager. I’ve been with Cisco’s Learning@Cisco team since 1999, – I’m passionate about how people’s lives can change for the better through education and certification.
Daniel: Elaine, why did Cisco create an expert level design program? What kind of people should be looking at the CCDE?
Elaine: Cisco has very well established expert-level certifications for network engineers in various fields which assess configuration, implementation, troubleshooting and operations skills; however, these certifications were never aimed to assess design skills. Continue reading
In this post, I will be doing a brief commentary on creating and maintaining a physical port mapping spreadsheet. A port mapping spreadsheet is useful for keeping track of used/available ports on your network equipment, thoroughly documenting to which remote device each port connects, and generating configuration scripts to update port descriptions on the equipment.

Although not immediately obvious, the FirePOWER Series 3 devices can do a form of IPS on a stick. This means that the capability described here should be available to the current appliance versions of the FirePOWER managed devices. The premise involves connecting broadcast domains (VLANs) to bring the managed device inline between the initiator and responder of a flow. Configuration is fairly straightforward but does have some caveats.
Caveats
The diagram shows two devices in the same VLAN (we will assume /24 for the configuration). The device on the top is in VLAN 100. The FirePOWER managed device bridges VLAN 100 to VLAN 101 and allows the two devices to communicate directly with one another. The connection to the FirePOWER device is a single 802.1q trunk.
Frames arriving on VLAN 100 will be processed and egress with a VLAN tag of 101. This configuration is similar to a Continue reading
Gigabit Passive Optical Network (GPON) is an interesting alternative to traditional Ethernet in situations where Ethernet might be difficult or expensive to deploy. Network engineers Andy Burridge and Wallace Chase join us to talk about exactly what GPON is, potential use cases for the technology, and network design challenges.
