I cant Back up the Core Switch

Dear Sir,

I try to recover my Cisco Core Switch 6506 from ROMmon mode using Boot command, after experiencing eletric/power problem.

Suddenly I cannot back up the flash file from the cisco.

How can I get back/return this to normal mode the System image of the device.

Thank you.

I cant Back up the Core Switch

From your screenshot, it looks like you're trying to copy the crash file, and you're specifying the incorrect location. The crashinfo file is a textfile that tells you what happened and why the system crashed, but it's not the system image. Do a "dir" or "dir sup-bootdisk:" to see your image.

HTH,
John

If you have a tftp server, try this:

copy sup-bootdisk: tftp:/

Re: I cant Back up the Core Switch

You can set the IOS to load on boot with "boot system flash sup-bootdisk:" under global config. You may want to check that your configuration register is set to 0x2102. If not, I would change it under global config with "config-register 0x2102". Write the config and reload. The boot command above will try to load, and if it can't load the image that you specify, it will look for an image in flash to load, so there's a failover mechanism if it can't find it.

Oh, to check you register do a "show ver | i Config"

Re: I cant Back up the Core Switch

Thank you for the help.

One more thing, Everytime that my Cisco Core Switch 6506 power off.

It will reboot on ROMmon Boot comand Mode.

How can I set my Cisco Core Switch to open normal during power on?

how to recover a Cisco Catalyst 6500/6000 series switch that runs Cisco IOS system software from either a corrupted or a missing boot loader image?

Thanks in advance.

Re: I cant Back up the Core Switch

This is my show version command result Sir.

How can I Apply the boot system flash? get into normal?

Can you tell me Sir, Step by Step. Thank you.

Re: I cant Back up the Core Switch

Try this:

From the prompt that you're at in the screen shot, type:

config t

boot system flash sup-bootdisk: (Image name is the one that you found in sup-bootdisk:)

end

wr

That will write the line to your startup config. When you reload, it will see that line and try to load the image. If it can't find the image that you type, it will search for an image in sup-bootdisk to load.

Re: I cant Back up the Core Switch

Dear Sir,

I read some forums, from Cisco this article describe the other solutions to solve the issue.

http://www.cciezone.com/?p=188

under global configuration mode

type boot config-register 0x2102

Which of these two command is correct?

Until now I did not restart my Core switch.

Thank you,

Michael
