Re: [HELP] NO flash files

said by Da Geek Kid:

reason for tftp is that it requires a CPU. Cat switches are ASIC based...

That reasoning doesn't wash. Just because a switch uses an ASIC for some wire-speed functions does not imply it doesn't also have a CPU.

Image is cute and irrelevant as 3560-X and 3750-X have Mgmt ports which do have tftp capability...

Geek Kid,
Are you saying the 3560 has no CPU?

Maybe I should explain it a little differently. All devices may have some sort of CPU. What I mean by CPU vs. ASIC. ASIC based devices (i.e. switches) mean that the Chip deals with the port and not the "software".

Perfect example is 4500s and 6500s. During the ROMMON mode you cannot set the TFTP to communicate with your PC on port G3/47... The only ports available are the ones on the Sup Module. It goes the same with any router that the only one available is e0/0. Now as for a switch, since all ports are handled by a separate set of chipsets usually a set of 4 or 8 ports are handled by one chip. These chips are non functional in ROMMON. IOS has to loaded and small firmwares get loaded on them to communicate with the IOS. The only way to push a bin file to flash on a switch without a Mgmt port is thru Console's XModem.

If only you'd said that about 10 or so posts ago... :P

I think youre the one who is confused, but with your terminology. We tend to go through these back and forths before what you really meant to say comes out.
