Hi, if I have a cisco switch with 16 Mb flash ram , that means I have to boot only 12.2 version , can I use TFTP server and force the switch to boot a 15 ios version? 3560-48PS-S is the switch and image ipbasek9-mz with 128 MB DRAM/16 MB flash !! on ebay they sell this switch close to 35$ and if is working with tftp, i can lab easy for my CCNP Switch exam!! Thank you!!!icon_thumright.gif

    Yes, it should work. while it only has 16mb of flash, it has 128mb of ram just like the models that can run version 15.

    but at 100mb, just downloading the version 15 iso is going to take 5-6 minutes. So, don't be in a hurry to start studying. So, you might have to wait for the switches to boot before booting anything else that need a switch connection.
