Upgrading the ios on a Cat Switch


1. Check the current version

To find out what version os, you are currently running, type 'sh ver' (see in red). For this example the switch is running on version 6.1(1) code. (see blue)

check current catos version 
01  c4003-devlab-1> (enable) sh ver

2. Check the flash for room

space in flash 
01  c4003-devlab-1> (enable)  sh flash
02 -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
03   1 .. ffffffff 9931da99  3fc33c   20  3916476 Feb 11 2002 14:49:18 cat4000-k9.6-1-2.bin
04 
05 7617732 bytes available (3916604 bytes used)

3. Download the new os to the switch

We are downloading the new os from a tftp server. The files location is at the URL: tftp://172.22.1.202/software/cat4000-k9.7-1-1.bin

download new catos 
01  c4003-devlab-1> (enable) copy tftp flash 
02  IP address or name of remote host [10.10.82.57]?  64.210.178.200

10  File has been copied successfully. 
11  c4003-devlab-1> (enable)

4. Check the flash for new file

Make sure that the file downloaded ok

check for download 
01  c4003-devlab-1> (enable) sh flash
02  -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
03    1 .. ffffffff 3fb14273  3e4084   17  3817476 Feb 24 2001 18:18:37 cat4000.6-1-1.bin

05  
06  3321380 bytes available (8212956 bytes used)
07  c4003-devlab-1> (enable)

5. Verify the new os is ok

This checks the crc, and makes sure that the file was downloaded ok.

check quality of download 
01  c4003-devlab-1> (enable)  verify bootflash:cat4000-k9.7-1-1.bin
02  CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
03  CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
04  File bootflash:cat4000-k9.7-1-1.bin verified OK
05  c4003-1> (enable)

6. Check current configs

You will need to change the configs so that the cat boots from the new os, here, just make sure that the cat was told to boot from a specific ios version, instead of the first file in flash, of from the network.

check config 
01  c4003-devlab-1> (enable) wr term
02  This command shows non-default configurations only.
03  Use 'write terminal all' to show both default and non-default configurations.
04  .......
05  
06  ....................
07  
08  ..
09  
10  begin
11  !
12  [... some lines removed ...]
13  !
14  ! -- set boot command
15  set boot config-register 0x2
16  set boot system flash bootflash:cat4000.6-1-1.bin
17  !

7. Set the correct ios to boot

Make the switch boot from the new ios version. First tell the switch the new ios to boot from.

set new catos to load 
01  c4003-devlab-1> (enable) set boot system flash bootflash:cat4000-k9.7-1-1.bin
02  BOOT variable = bootflash:cat4000.6-1-1.bin,1;bootflash:cat4000-k9.7-1-1.bin,1;
03  c4003-devlab-1> (enable) 
04  
05  ! -- Then clear the old command telling it to boot from the old os:
06  ! -- clear old boot command
07  c4003-devlab-1> (enable) clear boot system flash bootflash:cat4000.6-1-1.bin 
08  BOOT variable = bootflash:cat4000-k9.7-1-1.bin,1;
09  c4003-devlab-1> (enable) 
10  
11  ! -- and if your paranoid, you can double check the configs to make sure that that they took.
12  
13  c4003-devlab-1> (enable) wr term
14  This command shows non-default configurations only.
15  Use 'write terminal all' to show both default and non-default configurations.
16  .......
17  
18  ....................
19  
20  ..
21  
22  begin
23  !
24  [... some lines removed ...]
25  !
26  ! -- set boot command
27  set boot config-register 0x2
28  set boot system flash bootflash:cat4000-k9.7-1-1.bin
29  !

8. Reboot to new os

The switch must reboot to run the new catios. Yes, there will be an outage while this happens.

reboot 
01  c4003-devlab-1> (enable)  reset
02  This command will reset the system.
03  Do you want to continue (y/n) [n]? y

9. Checking the running version

Just incase something didn't look right at boot, you can check the running os again to make sure that the new ios took:

10. Delete old OS

You might want to wait on this step until you are sure that the new os is what you want. (maybe a couple of days to see if any bugs pop up.)

Look at the directory to get the correct filename.

delete old catos 
01  c4003-devlab-1> (enable)  dir
02  -#- -length- -----date/time------ name
03    1  3916476 Feb 11 2002 14:49:18 cat4000-k9.6-1-2.bin

12  c4003-devlab-1> (enable) 
13  
14  Then squeeze the file to "empty the trash".
15  
16  c4003-devlab-1> (enable)  squeeze bootflash:
17  
18  All deleted files will be removed, proceed (y/n) [n]? y

Appendix B: References

You will want to download the new code from cisco, and then keep it on a tftp server where the switches will have access to. The following links should be helpful in finding the correct ios, and answering questions about the different ios versions.
