Our Best CLI Cheat Sheet Cisco and HP: Carolina Advanced Digital

If you’ve purchased HP Networking equipment from us (Carolina Advanced Digital), and/or if you’ve worked with our Professional S ervices team on networking projects, you’re probably familiar with our go-to resource for all things CLI — The HP Networking and Cisco CLI Reference Guide.

We love this guide because it covers all the standard configurations you’ll use, showing Cisco side-by-side with HP ProVision and Comware versions 5 and 7. Compare CLI commands, get tips and tricks for configuring on specific platform, and view at-a-glance sample configurations in each section. Regardless of the switches you’re managing this little book (well, this BIG book- it’s 560 pages) will be your go-to CLI Bible.

The latest CLI Reference Guide version 3 is out, and we invite you to download it here for free and share in the CLI love.
