Looking for a great network diagram tool? I recommend the open source Dia program. It comes with built-in shapes for popular Cisco devices (same icons you see in most Cisco books). There are many other useful built-in icons and shapes as well.
The dynamic connectors move with the objects they’re linked to. It can be a little confusing at first, but you’ll get used to it after a couple drawings. It’s available as a supported package in most Linux distributions, and a Windows installer is available for the masses:
- http://sourceforge.net/projects/dia-installer/ (Windows Installer for Dia)
- http://dia-installer.de/ (Official Website for Dia Windows Installer, there’s some documentation here)
Linux users of the CentOS or RHEL (Red Hat Enterprise Linux) distributions can get dia using the EPEL (Extra Packages for Enterprise Linux) yum package repository. Once you have EPEL, you should be able to install with “yum install dia”. 🙂
