System Requirements
This example shows the autoboot configuration:
Console> (enable) show boot
BOOT variable = bootflash:cat4000.5-5-8.bin,1;
CONFIG_FILE variable = bootflash:switch.cfg
Configuration register is 0x102
ignore-config:disabled
auto-config:non-recurring
console baud:9600
boot:image specified by the boot system commands
Console > (enable)
Step 6 If the last line in the output of the show boot command is not boot:image specified by the boot
system commands
, use the set boot config-register command to set the boot configuration.
This example shows how to set the boot configuration:
Console > (enable) set boot config-register boot system
Configuration register is 0x102
ignore-config:disabled
auto-config:non-recurring
console baud:9600
boot:image specified by the boot system commands
Console > (enable)
Step 7 Use the set boot system flash command to prepend the promupgrade image to the boot string.
Note Make sure that you use the prepend keyword with the set boot system flash command. The
switch always boots the first image in the boot string, and you want the promupgrade image to
boot first.
This example shows how to prepend the promupgrade image to the boot string:
Console> (enable) set boot system flash bootflash:cat4000-promupgrade.6-1-4.bin prepend
BOOT variable = bootflash:cat4000-promupgrade.6-1-4.bin,1;bootflash:cat4000.5-5-8.bin,1;
Step 8 Reset the switch to boot the promupgrade program.
Caution No intervention is necessary to complete the upgrade. Do not interrupt the boot process by performing
a reset, power cycle, OIR of the supervisor engine, etc. for at least five minutes! If the process is not
allowed to complete, you may damage the switch and have to return it to Cisco for repair.
Upgrading the ROMMON may require up to 5 minutes because the switch boots the promupgrade
image. This special program erases the current ROMMON from Flash memory and installs the new one.
After installing the new ROMMON, the system resets again and boots the next image in the BOOT
string. If the BOOT string was configured as described in Step 7 on page 5, the next image is the software
image that the switch was originally configured to boot.
Note A Telnet session is disconnected when you reset the switch; you will lose connectivity to the
switch for approximately one minute.
If you are connected to the console serial port, output similar to the following is displayed after you reset
the switch:
0:00.530901:ig0:00:10:7b:aa:d3:fe is 172.20.59.203
0:00.531660:netmask:255.255.255.0
