Re: OT: When to upgrade bandwidth?

Hi Haroon.

You can find handy a document issued by Cisco internal IT, a capacity
planning case study. That one might answer some of your questions.

As for your "sh interface" output, as it was pointed out, way too many
errors and interface resets. Worth having a closer look at that.

Also you might conside using WAN optimization, Riverbeds perform very well
in that area, though costy.
