It has saved me a couple of times, as just a backup feature. It can easily do a snapshot before you do any change, and if something goes wrong, you can just rollback.

Once we have it running, it should be easier for us to program our IT rather than going case-by-case, by switches and different elements, or program it by hand.

I would like them to simplify the way you configure the Fabric. The process is quite complex. This can be a barrier to entry. For anything, where it should take two or three steps, you have ten steps

The challenging thing about Cisco ACI was we had to put a lot of effort into providing the customer the full picture, new standards, and new technology that they had to use. This was more challenging than deploying the product.

It is still not mature and has room to grow. As with any product out there, it requires time to develop.

Biannually, there is a new design delivered by Cisco. Thus, you are always running behind the new design, and it never stops. With Cisco ACI, this has been a nightmare.

The ACI user interface is complex and Cisco should improve it.
