strange cisco 2801 boot problem

muusitalo · ‎04-09-2008

Hi!

I changed compactflash cards on one of our cisco 2801's power

connected trying to get a 512MB

card partitioned to 128MB to work, and when I Installed this 512MB

card, router dropped

suddenly to rommon. I Switched power off and tried to boot with

original Card but router finds

image and decompresses and loads it but hangs after "Installed image

archive" prompt.

I tried booting also with flashcards from other (working) 2801's

without success. I made sure

that config-register is 0x2102 and also tried with 0x2142, 0x2141 and

0x2101.

I tried to dowload new version of IOS to flash from Romboot with

tftpdnld command, but it does

not work as router has lost it's MAC address. Correct port (fa0/0) was

connected and link was

up. Any ideas how to fix this problem?

Best Regads

Installed image archive

MACHINE JUST HANGS AFTER "Installed image Archive"

victorchen · ‎04-10-2008

I have two 2801 router have the same problem,

all stop in Installed image archive when I reload the router.

Hi ,

Please check the below link which may help you to come out of the ROMMON mode.

I can Boot router with image from flash, but my router hangs after "Installed image archive" prompt. Actually we have three 2801:s with similar problems.

TFTPNDLD command from rommon has following output:

rommon 11 > tftpdnld

IP_ADDRESS: 192.168.1.27

IP_SUBNET_MASK: 255.255.255.0

Somehow router has lost it's MAC-address?

Hi Guys,

Same problem, same routers, all afternoon digging around and finally solution reached until modifying cookie in ROMMON . First of all; let me say that when you modify this file your smartnet may not be useful anymore. So, if you have smartnet open a case to TAC and wait them to arrange an interactive session for you.

How I solve the issue is;

- Boot the router in ROMMON

- Go to priv mode (you need priv password; write "cookie" and copy&paste first line to the following web site http://ers.pp.ru/cgi-bin/priv.cgi
- In priv mode modify cookie file by using "cookie" command again. This may be very trick since every offset is represented in hex . That's why you need to dig more; you will see "FF"s on the corrupted part of this file (I am not talking about continous FF s at the end of the file).

-Change them base on the reference below: (I also used another running 2801's cookie for some true references)

          bytes 0x00-0x07: 04 ff c3 06 00 1e be b5    - MAC address (FA0/0,F0/1) you can change if you

And reload your router....

Friends,

I can confirm myself that a corrupt cookie on one of my ISR routers produced an identical issue - a router simply hanging during boot, unable to proceed. A corrupt cookie was found as the cause.

What I can recommend at this stage for everyone is to use the command show diag in IOS and cookie in ROMMON to display and back up the cookie values from their routers, and in case of cookie corruption, to have its original value using which it can be restored.

By the way, it is close to raising suspicions: why do these cookie values get corrupted so often? Every now and then, some router becomes a brick after the cookie value goes havoc. The thing is, if the cookie format was documented (there's nothing so special in it), it would be possible to repair the router in the field instead of RMAing etc.

Best regards,

Peter
