Holy crap 9600 baud is slow! I’m doing something different in loading a wiped switch, and I thought I would use an xmodem transfer. Go me! Since this is taking so long, I may as well post some switch basics as I go. (To note, my earliest speeds on the Internet were 14.4kbps modems back in high school.) I’ll also go ahead and put on some background music, the excellent Dubnobasswithmyheadman album from Underworld (a favorite!).
I have a completely wiped Cisco Catalyst 2950T switch. Even the flash has been erased (an eraser of love). If you boot it up, it gives an error and stops pretty quickly. A quick “dir flash:” will show nothing. I also have an ios version ready and waiting: c2950-i6k2l2q4-mz.121-22.EA8a.bin. For my console system I have an old Dell Latitude laptop (yeah, it’s one sexy-small laptop!) running a permanent install of BackTrack2.
To get the c2950-i6k2l2q4-mz.121-22.EA8a.bin file to BackTrack2, I decided to also test my tftp server and use tftp to transfer the file. My tftp server is at 192.168.10.108.
tftp 192.168.10.108 -c get c2950-i6k2l2q4-mz.121-22.EA8a.bin
Gosh, that’s easy. Now I need to connect up to the switch by plugging in necessary cables, including the power so that it powers on and loads. I decide to use CuteCom in BackTrack2 as my graphical terminal emulator. I change the baud rate to 9600 and click Open device. I type a few commands to get ready for my transfer.
switch: flash_init
Initializing Flash…
…The flash is already initialized.
switch: load_helper
switch: copy xmodem: flash:c2950-i6k2l2q4-mz.121-22.EA8a.bin
Begin the Xmodem-1k transfer now…
At this point the terminal is waiting for some data. CuteCom has a Send File button at the bottom where I can select the file and start transferring at the blistering 9600 speed! In fact, after writing this, I’m still only up to 15% completed. Ahh the joys of a wiped device that doesn’t even know what an IP address is yet.
Hope you’re able to breathe life into the Catalyst without any hitches!
Latitude C400’s for life. Most of what I do, I do on mine, decked out with a gig of RAM. It’s not going to play any games, but it’s extremely light, small, cheap, and really good for security/hacking type stuff 🙂

Yeah, that’s the box! I need to bump the RAM up again, but otherwise the laptop rocks.
