Top 20 Practical Cabling Tips for Network Engineers – Part One

networking-cables-1

Most engineers think that cable is simply plug and play. And mostly, that true. In recent years, Ethernet standards and manufacturing Here are 20 things that Network Engineers have forgotten or don’t know about network cabling in a two part series on things I have learned in twenty years of looking after networks.

Basics: Cisco VLAN Trunking Protocol – Transparent discard and passing VTP Packets

It’s a common discussion about when Cisco VTP protocol is actually forwarded through Cisco switches and when it’s isn’t. I’ve always gotten it somewhat confused and when I stumbled across some old notes on the topic I had an ah-hah moment. I’m answering the equation about when using VTP in your network, which versions are risky – that’s risky is terms of how do you prevent VTP updates from ‘crossing’ a switch.

I’ve been considering a small but vital problem in naming conventions in Networking. Namely, the use of underscores and hyphens in object names and devices. It’s a hot topic for argument when the time comes for corporate standards (and when Network Engineers have beverages in a public house). Now, I figure that there are three possible grammar options for making names – hyphens, underscore and CamelCase.
