Your Support Website: What You're Saying About Our New Design

We are taking stock of your reactions to the redesigned Cisco Support Website, especially as we weigh our next moves to simplify your most common and urgent online tasks. So if you have feedback to share, we want to hear it.

Here are some comments we have already heard from customers, partners, and industry web analysts:

  • "The new support page is much easier to navigate and easier on the eyes."
  • "Fantastic! I love what you've 'done with the place'…"
  • "No flash, all task…"

How similar is your experience?

  • What do you think of the Product Support tab – does it help you jump straight to technical content?
  • How do you use the Downloads tab – does it help you get directly to the software you need?
  • How much of an improvement is the new Contacts/Support Cases tab when you need direct assistance?

Your input was instrumental in this redesign, and we continue to rely on your thoughts as we gauge our success and plan our next steps. So, if you haven't visited the Cisco Support Website home page lately, give it a try and tell us what you think.
