IOS Upgrade via tftp

Dear Sir,

I am trying to copy IOS image to Cisco 4503-E switch via tftp in ROMMON mode as someone removed image from the flash.when i check rommon commands there is no xmodem or copy commands there.,so i went with tftp.The connection between the switch and my laptop ok.

So I use following command to transfer image to flash,

rommon>boot tftp://10.0.0.1/filename.bin

but there is error called "tftp session failed: Access violation " ,. I disable windows firewall and tried several times.

I mentioned  the set command output below.

rommon> set

   PS1=rommon! >

   ConfigReg=0x0102

   Rommonver=15.0(1r)SG2

   IpAddr=10.0.0.1

   Netmask=255.0.0.0

   Broadcast=10.255.255.255

   Gateway=10.0.0.254

   BootedFilename=tftp://10.0.0.2/ios.bin

(My image is file in the root directory of tftp server)

   

Please I kindly ask you to help me as soon as possible .

Thanks in Advaned

Use TFTPDNLD in Rommon

With the appearance of USB ports and SD card slot, xModem & TFTPdnld are old school and very slow.

I agree with you Leo . I just

I agree with you Leo . I just wanted to talk about "How to use TFTPDNLD"

BTW, Leo could you participate in my topic please ( Core switch selection ).

ConfigReg=0x0102

ConfigReg=0x0102

This value is incorrect.  

Connect a console cable to the supervisor card and reboot.  I want to see the entire boot-up process, including the error messages.

Dear Mr.Leo,

Dear Mr.Leo,

Thanks for the quick reply...

I attached the screen shot of booting process (I took it before configure ip address) and tftp error massage also.It may be useful too.

Hope your kind reply..

Hmmmm ... Look at the error

Hmmmm ... Look at the error message in the TFTP screenshot:  Directory name is invalid.  

And, WTF!, the supervisor card is a Sup7E.  Aside from the archaic method of uploading an IOS using TFTPdnld or xModem, the line card as a USB port and a SD card slot.  

The IOS can be loaded using either USB port of SD card slot.

Dear Mr.Leo,

Dear Mr.Leo,

"Bad magic number" means the

"Bad magic number" means the file is corrupt. 

Go to the Cisco website and compare the MD5 hash value of the file downloaded against the MD5 hash value found in the Cisco website.  Both values must match.
