Introduction

This document provides an example that shows how to upgrade the Cisco IOS® software release on a Cisco AS5800 access server dial shelf (DS) and router shelf (RS).

The Cisco AS5800 is a high-end access server based on distributed processor architecture. It utilizes dial shelf technology that provides line and call termination, and allows the router shelf to devote full attention to terminating protocols and other management duties. It is necessary to run similar versions of Cisco IOS software on both the dial shelf and the router shelf. If your system supports redundancy, you would have two dial shelf controllers, and hence need to upgrade both of them

The AS5800 has two different images associated with it. The images, their names and their appropriate locations are detailed in this table:

Image Name

Image Location

AS5800 system image

c5800-p4-mz.XXX Router Shelf slot0-slot1-disk0

Dial shelf controller (DSC) image

dsc-c5800-mz.XXX. DSC(s) slot0-slot1-disk0

How to Upgrade the Software Image

In order to upgrade the Cisco IOS software, you need to copy two images from CCO into your Trivial File Transfer Protocol (TFTP) or File Transfer Protocol (FTP) server.

You need to perform this procedure in two stages:

Upgrade the DSC Software

Complete these steps:

  1. Log in to the router shelf, and enter the show dial-shelf command to see where the DSC is located. In this example, the DSC is in slot 12.

    routershelf#show dial-shelf 
Slot    Board     CPU       DRAM          I/O Memory   State    Elapsed

Dial shelf set for auto boot

  2. Issue the execute-on slot 12 show version command to see the current version of Cisco IOS software.

    To check the current images stored in the flash, issue the execute-on slot 12 show flash command.

    Note: A DSC image requires about 2 to 3 MB of space. So, check the available space.

    Here is an example:

    dialshelf#
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1   .. image    CE650F8D  29F4AC   22  2618412 Oct 03 2001 08:12:48
 dsc-c5800-mz.121-5.XM5
2   .. image    E66E7E75  512D8C   37  2570336 Oct 03 2001 09:34:17
 dsc-c5800-mz-122-5

2806388 bytes available (5189004 bytes used)

  3. To delete a software image, issue the dsip console slave 12 command. This takes you from the router shelf to the DSC.

    routershelf#dsip console slave 12
Trying Dial shelf slot 12 ...
Entering CONSOLE for slot 12

  4. Press CTRL + C thrice (^C^C^C), to end this session.

    Note: If you use authentication on the DSC, you need to use a local password. The DSC does not support authentication, authorization, and accounting (AAA).

  5. Next, you need to delete and "squeeze" images from the DSC.

    dialshelf#show flash
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1   .. image    CE650F8D  29F4AC   22  2618412 Oct 03 2001 08:12:48
dsc-c5800-mz.121-5.XM5
2   .. image    E66E7E75  512D8C   37  2570336 Oct 03 2001 09:34:17
dsc-c5800-mz-122-5

2806388 bytes available (5189004 bytes used)


ds-dynamite#delete dsc-c5800-mz.121-5.XM5
Delete filename [dsc-c5800-mz.121-5.XM5]?

    Note: If the file is deleted, you can squeeze the file.

    Note: If you have Ethernet connectivity on the DSC, you can use the copy tftp flash command to upload the new image.

  6. After you have uploaded the new image, and you have more than one image in flash, issue the boot system flash command.

  7. If you do not have Ethernet connectivity, you need to return to the router shelf. To do so:

    Press CTRL + C thrice (^C^C^C), to end this session. Alternatively, type exit.

       dialshelf#
   Terminate NIP IO session? [confirm]
   [Connection to Dial shelf slot 12 closed by local host]
   routershelf#

  8. Now execute the copy tftp dsc12-slot0 command to copy an image from the router shelf to the DSC.

    routershelf#copy tftp: ?
bootflash:        Copy to bootflash: file system
disk0:            Copy to disk0: file system
disk1:            Copy to disk1: file system
dsc12-bootflash:  Copy to dsc12-bootflash: file system
dsc12-nvram:      Copy to dsc12-nvram: file system
*dsc12-slot0:     Copy to dsc12-slot0: file system
*dsc12-slot1:     Copy to dsc12-slot1: file system
flash:            Copy to flash: file system
ftp:              Copy to ftp: file system
lex:              Copy to lex: file system
null:             Copy to null: file system
nvram:            Copy to nvram: file system
pram:             Copy to pram: file system
rcp:              Copy to rcp: file system
running-config    Update (merge with) current system configuration
slot0:            Copy to slot0: file system
slot1:            Copy to slot1: file system
startup-config    Copy to startup configuration
system:           Copy to system: file system
tftp:             Copy to tftp: file system

    Here is an example:

    routershelf#copy tftp: dsc12-slot0:
Address or name of remote host []? 192.1.1.1 -> IP address tftp-server
Source filename []? dsc-c5800-mz.121-6 -> Image you want to upload
Destination filename [dsc-c5800-mz.121-6]? 
Accessing tftp://192.1.1.1/dsc-c5800-mz.121-6...
Loading dsc-c5800-mz.121-6 from 192.1.1.1 (via Ethernet0/1/0)

!!!!!!!!!!!
[OK - 2390676/4781056 bytes]

2390676 bytes copied in 132.32 secs (18111 bytes/sec)
routershelf#

  9. To verify the image, use the execute-on-slot 12 show flash command.

    dialshelf#
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1   .. image    CE650F8D  29F4AC   22  2618412 Oct 03 2001 08:12:48

dsc-c5800-mz.121-6

415584 bytes available (7579808 bytes used)

  10. Return to the dial shelf. To do so, issue the dsip console slave 12 command, and apply the correct boot system command. Remember to save the configuration.

  11. Return to the router shelf. To do so, type exit, or press CTRL + C thrice (^C^C^C).

  12. Repeat this procedure if you have a second DSC card, to ensure that both run the same Cisco IOS Software Release. To do this, you can use the same commands. The only change is that the slot number will change from 12 to 13.

    Note: While the DSC(s) and router shelf are not running the same IOS image, you will probably be unable to communicate with the DSC through the router shelf.

Upgrade the Router Shelf Software

The procedure to upgrade a Cisco 7200 router is exactly the same as that described here for the AS5800.

  1. First, check which Cisco IOS software images are in flash:

    routershelf#show flash
-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name
1  ..  image  CD880075  CAEA6C  36    13167084 Oct 03 2001 09:35:14
c5800-p4-mz-122-5

7411092 bytes available (13167212 bytes used)

  2. Delete any images or files that are no longer required. You must have a sufficient number of bytes available to accommodate the new image.

    routershelf#delete slot0

    Note: It is recommended that you keep a backup copy of the software image from which you are currently upgrading, or a previously preferred image, in case there are any problems with the new image.

  3. Squeeze the flash. To do so, issue the squeeze slot0: command.

    routershelf#squeeze slot0:

  4. Download the new image to flash. For example, to download from a TFTP server, use this command:

    routershelf#copy tftp: slot0 or copy tftp slot1:

    If you use a 4MB disk, you need to use the copy tftp disk0 command. For example:

    routershelf#copy tftp: flash
Address or name of remote host [192.1.1.1]? 
Source filename [dsc-c5800-mz.121-6]? c5800-p4-mz.121-5.XM5
Destination filename [192.1.1.1]? 
Accessing tftp://192.1.1.1/c5800-p4-mz.121-5.XM5...
Loading c5800-p4-mz.121-5.XM5 from 192.1.1.1 (via Ethernet0/1/0): !

    Note: Remember to apply the boot system flash command if you have multiple images.

Boot the Dial Shelf and Router Shelf

This section describes the procedure to boot the Dial Shelf, and the Router Shelf.

Complete these steps:

  1. Use one of these startup procedures:

    • Cool start: If you have saved both configurations on the router and dial shelf, power off the dial shelf and router shelf, then power them on again.

    • Warm start: Login into the DSC with dsip console slave 12 command, as shown here:

      routershelf#dsip console slave 12
Trying Dial shelf slot 12 ...
Entering CONSOLE for slot 12
Type "^C^C^C" to end this session

dialshelf#enable
dialshelf#write
Warning: Attempting to overwrite an NVRAM configuration previously
written by a different version of the system image.
Overwrite the previous NVRAM configuration?[confirm]
Building configuration...
[OK]

dialshelf#reload
Proceed with reload? [confirm]

  2. The keyboard will be frozen since the DSC is being reloaded. You cannot use exit in this case.

    Press CTRL + C thrice (^C^C^C) to exit the dial shelf.

  3. If you are back on the router shelf, write the config and reload the box.

    routershelf#reload
Proceed with reload? [confirm]

Verify

This section enables you to verify the process used to boot the Dial Shelf, and the Router Shelf.

When you have reloaded the router shelf, the following message is displayed on the console after a few minutes. Press Return to get started.

*Oct 9 09:26:46.763: %SYS-6-BOOTTIME: Time taken to reboot after
 reload = 123 seconds
*Oct 9 09:26:55.507: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 12 
Succeeded

Now you can use the execute-on slot 12 show version command to verify if the router shelf and dial shelf run the same IOS software version. If they do, wait for a few minutes until all Feature Boards are booted up.

*Oct 9 09:29:28.515: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 2
Succeeded
*Oct 9 09:29:28.615: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 3
Succeeded
*Oct 9 09:29:28.807: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 4
Succeeded
*Oct 9 09:29:28.887: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 5

*Oct 9 09:29:29.915: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 0
Succeeded
*Oct 9 09:29:30.587: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 6
Succeeded
*Oct 9 09:29:30.699: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 7
Succeeded
*Oct 9 09:29:30.823: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 8
Succeeded
*Oct 9 09:29:30.887: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 9
Succeeded
*Oct 9 09:29:30.991: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 10
Succeeded
*Oct 9 09:29:31.115: %DSIPPF-5-DS_HELLO: DSIP Hello from shelf 1 slot 11
Succeeded

Note: If you have fewer cards in the chassis, the bootup time will be much faster.
