We are planning a network upgrade to our site (we are currently on a Cisco C4507R-E that is slowly dying).
On our access layer, we have mostly Cisco C2960-X switches. I was planning on stacking those (we don't have the stacking modules yet) to increase the bandwidth between them, and then using a DAC to connect the master in the stack to our Aruba 5400R that we are getting next week. However, on a call with Aruba, they said they could not certify that a DAC running between a C2960-X SFP+ port to an SFP+ port on the 5400R would work. Does anyone have any suggestions as to what I should do in this scenario? The C2960-X and 5400R are in the same closet, if that helps. Thanks to anyone who helps, and happy to provide more details if necessary.
