Recording of the process from cisco3169 CatOS to Native IOS

Engine: WS-SUP720-3B Master/Slave
Line Card: Five WS-X6148X2-45AF.
Cisco CompactFlash Memory Card, 128 MB 2.
The device was originally in cisco ios mode, but because IOS didn't support WS-X6148X2-45AF line cards at the time so the CatOS mode to support the above line card, cisco launched the supported IOS version s72033-advipservicesk9_wan-mz.122-18.SXF.bin, the customer requested to change to the IOS version again. The two CompactFlash Memory cards were formatted in the original IOS mode, and can be written to catos and IOS in both modes during the upgrade. The upgrade process is as follows:

1. Unplug the backup engine to support hot swapping.) Upload the IOS image file to CompactFlash Memory Card in catOS. Because IOS is more than 70 MB in size, TFTP cannot be used for transmission and is not reliable. Therefore, you can use FTP for transmission and enter set ftp username; set ftp password to set the called FTP user name and password. Run:

SWITCH_1> (enable) copy ftp disk0:
IP address or name of remote host <172.21.239.40>?
Username for ftp?
Password for User ftp <>:
Name of file to copy from? S72033-advipservicesk9_wan-mz.122-18.SXF.bin

51290112 bytes available (76603392 bytes used)

2. view the current vswitch startup variable. The register value is 0x2102. Next, modify this value to 0x0.

SWITCH_1> (enable) sh boot
BOOT variable = bootflash: cat6000-sup720cvk8.8-4-3.bin, 1;
CONFIG_FILE variable = bootflash: switch. cfg
Configuration register is 0x2102
Ignore-config: disabled
Auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 9600
Boot: image specified by the boot system commands
Image auto sync is enabled
Image auto sync timer is 120 seconds

3. Modify the register value to 0x0.

SWITCH_1> (enable) set boot config-register 0x0
Configuration register is 0x0
Ignore-config: disabled
Auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 9600
Boot: the ROM monitor

4. Confirm that the value has been modified and reset.

SWITCH_1> (enable) sh boot
BOOT variable = bootflash: cat6000-sup720cvk8.8-4-3.bin, 1;
CONFIG_FILE variable = bootflash: switch. cfg
Configuration register is 0x0
Ignore-config: disabled
Auto-config: non-recurring, overwrite, sync disabled
ROMMON console baud: 9600
Boot: the ROM monitor
Image auto sync is enabled
Image auto sync timer is 120 seconds
SWITCH_1> (enable) reset

5. The system restarts and enters the ROMMON mode. Enter SET to view environment variables.

9. Format sup-bootflash in IOS format

Router # format sup-bootflash:
Format operation may take a while. Continue?
Format operation will destroy all data in "sup-bootflash:". Continue?
Format of sup-bootflash complete
Router # dir sup-bootflash:
Directory of sup-bootflash :/
No files in directory

10. This step is an optional step to verify whether the flash card can be written. If the flash card can be written, no additional lattice is required. A small IOS file can be used to write IOS files to disk0 using the TFTP protocol. During the conversion process, data can be written. Therefore, the flash card is not re-formatted, And the IOS upload process is not required.
11. Modify the startup parameters. Start the vswitch with the IOS image in disk0 next time. Save

Router (config) # boot system flash disk0: s72033-advipservicesk9_wan-mz.122-18.SXF.bin
Router (config )#
Router # wr m

12. display the register value of the exchange processor. Because in catos mode, we modify the register value of the exchange processor to 0x0, so we have to change it back to 0x2102.
Router # remote command switch show boot
BOOT variable = bootflash: cat6000-sup720cvk8.8-4-3.bin, 1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist

So far, the main engine has been converted. Turn off the power, unplug the main engine, insert it into the backup engine, and repeat the above to convert it. After the backup engine is converted, you can insert the primary engine directly. The backup engine is active while the master engine is hot standby. After the master engine is fully started, you can plug and unplug the backup engine once. This will restore the master to active and standby to hot standby.
In this version, the redundancy mode is SSO, so the ping packet is not lost when any engine is plugged in.
