Notes, Tips & Tricks: Cisco

This is a notes page, extended with tips & tricks. This page is not really documentation, just stuff for me to remember. Sometimes things will get removed from these pages and turned into real documentation, sometimes not. You might find these notes to come in hand, maybe not. For me, it's just things I don't want to forget.

Fast Overview All Ports

The 'show interfaces status' command will give you a quick overview of port configuration:
