I would like to backup my IOS but having some issues as follows -
What I noticed is that if I do >Sh Version, I see the following -
''System image file is "flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin".
If I do >Sh Flash, I see the following -
C3550-ipservices-mz.122-35.SE5 - Which I think is not valid coz its not a .bin file???
I don't know why Flash shows this and version shows something different.
What should I copy? Should I copy -
1 - c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin
2 - flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin
3 - c3550-ipservices-mz.122-35.SE5.bin
You don't see a .bin because it's a directory. The full path is flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin so either change directory to flash:c3550-ipservices-mz.122-35.SE5 or use the full path when you are copying it.
I have't tried those as I am at work right now but I will do this. Again, either
cd flash:c3550-ipservices-mz.122-35.SE5 OR
cd flash:/c3550-ipservices-mz.122-35.SE5/. What are they going to do?
just follow joshua's directions... cd means change directory... it will put you in that directory... if you get lost use
that means print working directory... pwd shows you what directory you are in...
cd .. (enter) will bring you back to the root direcory... check out some basic dos and linux commands for filesystems... ios uses a few of them
Thanks everything is working fine.
Got into other big issue now -
What I did -
On my c3550's switch, I saved 3500xl's IOS on its flash and boot the 3550 switch with -
Config#boot system flash:3500xl ios
And now I am down hard.
I should have used -
Config#boot sytem tftp:3500xl
This was for just testing purposes.
Whats the solution now???
You should have ROMMON access to the device. This should allow you to boot from the image. So if you do a
rommon> dir flash:
It should show you what folders are in flash. You can then issue the boot command with the full path.....which would be something like
Here is a trick to learn with CIsco IOS - it is an easy way to tell if what you are looking at is a directory or an IOS. First off, does it have ".bin" at the end of the name? If not, check how large the object is, if it's small, you're looking at a directory. On current Cisco IOS they do not show the full size of the directory and it's contents when you do a "dir filesystem".
It's kept me safe for years now.....
Sorry, I am a newbie + I don't know what ROMMON is.
Right now, cursor is still blinking, not letting me do anything.
I searched online and I see this -
1. Turn the switch off, hold in the mode button on the front when you plug it back in and until the stat light goes out.
2. If you see Switch: on the console, type init_flash
3. Type load_helper
4. Type Dir flash: and check for a .bin image (IOS)
5. If you have a .bin file you can boot from it by typing boot flash:filename.bin
6. If that fails, you'll have to use xmodem to copy over a valid IOS image -> copy xmodem: flash:filename.bin. Setup your terminal to send the file via xmodem
-> In hyperterminal use the menu option of Transfer->Send File: Select the file and Protocol of Xmodem.
7. Wait a LONG time...
8. When the image has copied over, you can type boot flash:filename.bin. Otherwise, if your config register is correct, you could simply reboot. However, you'll probably want to upgrade it when you put the new IOS on it. Use
boot system flash:filename.bin once it's loaded to set where it boots.'
I followed this and nothing happens after typing - 'init_flash' or anything.
Still searching ...
Yes, I got it.
I was able to boot it from Flash.
Im going to delete the bad IOS from flash. I dont know how but lets see.
Oh mannn ...
Deleted BAD IOS now.
Now, I will see what is this ROMMON now.
Can someone tell me why do I see in sh ver > flash:c3550-ipservices-mz.122-35.SE5/c3550-ipservices-mz.122-35.SE5.bin
Why does it show me twice / ?
It is fine in flash though.
