We have decided to replace current cisco devices with new model and need help for comparison between Old and New devices with below required details,
Required Details :- 1) Number of port(ex. 48) 2) Interface speed(ex. 1Gbps) 3) Interface geometry(ex. RJ-45/SFP)" 4) DRAM 5) Flash memory 6) Rack Unit/mount 7) Dimensions (H x W x D) Power supply 9) Power consumption
Old Devices New Devices Catalyst6807-XL Catalyst9400 and Catalyst9600 Catalyst2960X & Catalyst2960CX Catalyst9200 and Catalyst9300 Catalyst3850 Catalyst9300 ASA5585-X Firepower 4112(ASA mode)
Unless someone here did this work and will be kind anough to share here, you need to go to each Data sheet and do it yourself. If I had, I would share but I hadn´t to do this so far.
I would create a spreadsheet with all the device side by side and every requirement on the list and then using the Datasheet I would go filling in every requirement. At the end you have a grasp of each one´s capacity and differences.
