Conversion on Supervisor Engine with MSFC1

From NesevoWiki
Jump to: navigation, search

Step 1

Establish a console connection to the SP.

Log your console session as a best practice. The log enables you to capture a record of the session and compare the log to the steps in this document, if you need to troubleshoot. For example, in Windows HyperTerminal, choose Transfer > Capture Text in order to log a console session. Refer to Connecting a Terminal to the Console Port on Catalyst Switches for more information.

Step 2

Back up the CatOS configuration from the Supervisor Engine and the Cisco IOS Software configuration from the MSFC1.

You need to reconfigure the switch after you convert to Cisco IOS Software as the system software because the conversion process loses the configuration. If you back up the files, they can serve as a reference after the conversion or as a backup if you decide to convert back to CatOS. Issue the copy config tftp command on the Supervisor Engine and the copy start tftp command on the MSFC1 in order to back up the configurations.

Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for more information on the use of the copy config tftp and copy start tftp commands to back up configuration files.

Step 3

Issue the show module command in order to confirm that the PFC and the MSFC1 are installed in the switch.

Note: You cannot run a Cisco IOS Software image (c6sup11*) without a PFC and an MSFC.

Step 4

Verify that the Cisco IOS Software image (c6sup11*) is available on the SP bootflash or on the PC card in slot0 of the Supervisor Engine module.

Note: Where you choose to store the Cisco IOS Software image (c6sup11*) depends on the Supervisor Engine flash device capacity and image size.

Issue the dir command in order to verify the location of the Cisco IOS Software image (c6sup11*).

   Console> (enable) dir bootflash:

   Console> (enable)

If the Cisco IOS Software image (c6sup*) is missing from either bootflash: or slot0:, download the image. Step 5 provides this procedure. If the image is present, go to Step 6. Step 5 (Optional)

Note: Complete this step only if the Cisco IOS Software image (c6sup11*) is missing from either bootflash: or slot0:. See Step 4 in order to determine if you need to complete this step.

Issue the copy tftp bootflash: command or the copy tftp slot0: command in order to download the image to either the SP bootflash or to the PC card in slot0.

Note: You might need to format the PC cards if it has never been used before or if it was formatted with the Cisco IOS Software algorithm. Issue the format slot0: command or the format slot1: command or both commands in order to format PC cards on a Supervisor Engine 1, 1A or 2.

Note: You can free up space as necessary on the flash devices. Issue the delete bootflash: command or the delete slot0:filename command in order to delete the file. Then, issue the squeeze bootflash: command or the squeeze slot0: command in order to erase all deleted files from the device.

   Router#

Step 7

Issue the dir bootflash: command in order to verify that the MSFC1 boot image is present on the RP bootflash.

A boot image for the MSFC1 (c6msfc-boot) is a requirement and must be in the RP bootflash.

   Router#dir bootflash:
   Directory of bootflash:/
       1  -rw-     1879040   Nov 02 2003 22:29:32  c6msfc-boot-mz.121-19.E1a

If the c6msfc-boot image is missing from the RP bootflash, download the image. Step 8 provides this procedure. If the image is present, go to Step 9. Step 8 (Optional)

Note: Complete this step only if the c6msfc-boot image is missing from the RP bootflash. See Step 7 in order to determine if you need to complete this step.

Issue the copy tftp bootflash: command in order to download the image to the RP bootflash.

Note: You can free up space as necessary on the RP bootflash. Issue the delete bootflash:filename command in order to delete the file. Then, issue the squeeze bootflash: command in order to erase all deleted files from the device.

   Router#copy tftp bootflash:

Step 9

Verify that the BOOTLDR variable statement points to the c6msfc-boot image in RP bootflash and that the configuration register is set to 0x2102. This setting tells the MSFC1 to boot automatically.

Issue the show bootvar command in order to check the BOOTLDR variable and configuration register settings.

   Router#show bootvar
   BOOT variable = sup-slot0:c6msfc-jsv-mz.121-19.E1a,1
   CONFIG_FILE variable =
   BOOTLDR variable = bootflash:c6msfc-boot-mz.121-19.E1a
   !--- The BOOTLDR variable statement is set correctly for the MSFC1. 
   Configuration register is 0x2102
   !--- The configuration register is set to 0x2102, which is  correct.
   Router#

If the BOOTLDR variable statement or the configuration register is not set correctly, complete Step 10 in order to change the setting. If both these settings are correct, go to Step Step 11 . Step 10 (Optional)

Note: Complete this step only if the BOOTLDR variable statement or the configuration register was not set correctly. See Step 9 in order to determine if you need to complete this step.

Issue these commands in order to set the BOOTLDR variable statement and change the configuration register setting:


   !--- Verify the boot image name.
   Router#dir bootflash:
   Directory of bootflash:/

   CONFIG_FILE variable =
   BOOTLDR variable = bootflash:c6msfc-boot-mz.121-19.E1a
   Configuration register is 0x2102
   Router#

Step 11

In order to go back to the SP, press Ctrl-C three times on the RP.

Note: If you issued the session module command in order to access the RP, you must issue the exit command instead of Ctrl-C.


   !--- Press Ctrl-C three times.

   !--- This is the SP console prompt.

Step 12

Change the configuration register setting on the SP so that the switch does not boot the CatOS image and goes to ROMmon.

   Console> (enable) set boot config-register 0x0
   Configuration register is 0x0
   ignore-config: disabled
   auto-config: non-recurring, overwrite, sync disabled

   BOOT=bootflash:cat6000-supk8.8-1-1.bin,1;
   rommon 2
   !--- Note: This prompt is SP ROMmon.

Cisco IOS Software does not use the CONFIG_FILE environment variable, so the variable can cause a problem. In order to avoid the problem, remove either bootflash:switch.cfg or slot0:switch.cfg from the environment settings. Issue these commands:

   rommon 2 > CONFIG_FILE=
   !--- Note: This prompt is SP ROMmon.
   !--- The CONFIG_FILE statement is case sensitive and is all capital letters.
   rommon 3 > BOOT=
   !--- The BOOT statement is case sensitive and is all capital letters.
   rommon 4 > confreg 0x2102


   You must reset or power cycle for new config to take effect
   !--- When you set the config register to 0x2102, the SP autoboots once
   !--- the BOOT variable is set to the correct IOS image file name after it 
   !--- converts to Native IOS mode.

Step 15

Boot the switch with the Cisco IOS Software image (c6sup11*).

Issue either the dir bootflash: command or the dir slot0: command. The command you issue depends on the device to which you previously downloaded the Cisco IOS Software image. Then, issue the boot bootflash: command or the boot slot0:filename command in order to start the bootup sequence.

Step 16

At this point, the Cisco IOS Software image (c6sup11*) has successfully booted, but the Supervisor Engine Flash devices are still formatted with the previous CatOS algorithm. Therefore, Cisco IOS Software cannot correctly write to sup-bootflash: or slot0:. You need to reformat these Flash devices and replace the images that are on the Flash devices.

Issue the format command in order to format both the Supervisor Engine bootflash and slot0 Flash devices.

   Router>enable
   Router#format sup-bootflash:
   Format operation may take a while. Continue? [confirm]
   !--- Press Enter or Return.
   Format operation will destroy all data in "sup-bootflash:".  Continue? [confirm]
   !--- Press Enter or Return.


   Format of sup-bootflash complete
   Router#
   Router#format slot0:
   Format operation may take a while. Continue? [confirm]
   !--- Press Enter or Return.
   Format operation will destroy all data in "slot0:".  Continue? [confirm]
   !--- Press Enter or Return.
   Enter volume ID (up to 64 chars)[default slot0]:
   !--- Press Enter or Return.
   Format of slot0 complete
   Router#

Step 17

When you format the Supervisor Engine Flash devices in Step 16, the Cisco IOS Software image (c6sup11*) used to boot the Supervisor Engine, as well as all data on the device, is erased. You need to recopy the Cisco IOS Software image (c6sup11*).

Note: Remember that the conversion lost the configuration. You need to configure an IP address and possibly static or dynamic routing in order to reestablish connectivity to your TFTP server. Verify that you can ping your TFTP server from the switch.

Issue the copy tftp command in order to copy the Cisco IOS Software image (c6sup11*) to either the sup-bootflash: or slot0: Flash device.

   Router#copy tftp slot0:
   !--- The Cisco IOS Software image (c6sup11*) copies to slot0: in this case.
