Cisco Catalyst 2900

I reset a Cisco Catalyst 2900 series switch. I also removed the IOS image from it. So currently there is nothing in the flash directory.

the image I am attempting to load will not transfer to flash. The image is c2900xl-c3h2s-tar.120-5.WC17.tar

The switch right now has a prompt.

Switch:

I have attempted to copy the ISO via xmodem using copy xmodem: flash:c2900xl-c3h2s-tar.120-5.WC17.tar

For some reason it will not copy and when I attempt to boot it says "Boot process failed"

I was doing this using Hyper terminal and Tera Term.

The .tar file includes the actual IOS image and the web UI files. In order to recover the switch, you're going about it the right way, but you need the .bin file rather than the .tar file. You can extract the .bin from the .tar and upload that using xmodem to do a basic recovery. You can then install the full .tar image once the switch is operational again.

Should I then just use Tera Term and do a copy xmodem flash:c2900xl-c3h2l9s-mz.120-5.WC17.bin

I attempted the copy xmodem. It went all the way to 100%,

I then received

Modem: : I.O error, any idea what that means?

Thanks

Something didn't complete properly with the transfer. Have you tried Xmodem-1K?

I have not, looks like Tera Term version I have only has Xmodem. Something else I should be using?

I'm a Mac user myself and have never used TeraTerm. I just use screen and sz, personally.

A little bit of research indicates that you can do an Xmodem-1K transfer from TeraTerm by using option 3 on the macro version of the command:

xmodemsend 'c2900xl-c3h2l9s-mz.120-5.WC17.bin' 3

Not sure if there's a similar option for doing it through a GUI.

I deleted the flash on the device using,

Erase flash:

Now, when I attempt to copy the new .BIN file to the switch is says "Not enough space available"

I show no files when issuing a dir flash: command. Is there some other command that needs to be issued to completely clean up the space?

Once IOS has booted, the "squeeze flash:" command is necessary to recover the previously-used space.

If you can't get to a functioning IOS, you should format the flash from rommon to start from a clean slate.

I was able to format the flash and start from a clean slate. I now have the .BIN file copied into flash. But when I got to copy the config back down. I receive the error again saying not enough space. It shows there is plenty of space available. The config is only 3.96KB ?

Leaving the configuration file aside for the moment, are you able to boot the switch into its IOS yet?

Once the switch boots up properly, you can either tftp the config to it or copy it in via the console. Note that the console buffer is pretty small so it's far better to configure IP and use TFTP to copy the config to the startup-config. Then reboot WITHOUT SAVING and you'll be back in business with your temporary config gone.

You will also have to rebuild your vlan database manually if you had vlans configured, as that is stored separately from the config on these switches.
