how to load my ios file back?

the_return_of_the_Ring

i'm upgrading the flash of my 2620. i know there's no ios in the new flash and the router will lead u to rommon>, but cisco website only tells u how to do the flash upgrade, i didn't see instructions on how to load back the ios file from tftp server. any body give a clue?

32m/8f upgrading to 64/16, the bootup shows 64mb memory recognized, then into rommon>, i'm not sure any command to use.

You can look at the ROMmon Recovery for the Cisco 2600 Series Router and the VG200

But down at the bottom of that doc is the direct link to Using the tftpdnld Command

You could also try the Xmodem Console Download Procedure Using ROMmon link, if you like pain.

I had tried both. see the result.

tftpdnld

Missing or illegal ip address for variable IP_ADDRESS
Illegal IP address.

usage: tftpdnld [-r]
Use this command for disaster recovery only to recover an image via TFTP.
Monitor variables are used to set up parameters for the transfer.
(Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.)
"ctrl-c" or "break" stops the transfer before flash erase begins.

The following variables are REQUIRED to be set for tftpdnld:
IP_ADDRESS: The IP address for this unit
IP_SUBNET_MASK: The subnet mask for this unit
DEFAULT_GATEWAY: The default gateway for this unit
TFTP_SERVER: The IP address of the server to fetch from
TFTP_FILE: The filename to fetch

The following variables are OPTIONAL:
TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default), 2=verbose
TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=7)
TFTP_TIMEOUT: Overall timeout of operation in seconds (default=7200)
TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1)
FE_SPEED_MODE: 0=10/hdx, 1=10/fdx, 2=100/hdx, 3=100/fdx, 4=Auto(deflt)

Command line options:
-r: do not write flash, load to DRAM only and launch image
rommon 17 > xmodem c2600-js-mz.122-19.bin
Do not start the sending program yet...
File size Checksum File name

I prefer using tftpdnld, but the problem is, i don't know what the connection would be? what ip should i assign to 2620's fa port? i used 192.168.110 just because my tftp server is 192.168.0.102. But, apparently the display told me wrong ip. I setup all the info in rommon> as below
rommon>ip_address=192.168.0.110
rommon>ip_network_mask=255.255.255.0
rommon>default_gateway=192.168.0.1
rommon>tftp_server=192.168.0.102
rommon>tftp_file=/ios/c2600-js-mz.122-19.bin

Did you check the results of the variables with the SET command?

mikej412

is it case sensitive?
IP_ADDRESS vs ip_address

the_return_of_the_Ring

I guess the trick will be the ip address of 2620's fastethernet port. who know what it shall be? with what can i decide the address.

Or, you just give it the UPPER_CASE environment variables it seems to be looking for.

the_return_of_the_Ring

oh my god!(God!), mike(Mike) u'r damn right!!! I never think it's case sensitive! come on it's on a command line! does DOS command case sensitive?

now it's done, i'm running enterprise edition to figure out VLAN. Thanks everyone!

Cisco programmers tend to be unix/linux types meaning they think in case sensitivity by default, so do I. Uppercase tokens for variables are common. filty habit.

Hey -- my 20 year UNIX anniversary has got to be coming up soon -- if it hasn't already passed!

Maybe I should look for an old AT&T 3B2 on eBay -- and I could put it out in the Barn in winter to keep the Barn Cats warm!

This is a good practice in more advanced Cisco exams. Use upper/mixed case to make your named items (route maps, key chains, access lists, etc.) stand out in a configuration file. It's the same principle, and it can save you time during troubleshooting.
