Show Boot Command and Upgrades

Unanswered Question

I recently upgraded software on three Cat 4006 switches. I followed articles found on the Cisco support site and the upgrades seem to be successful. I upgraded all three to Version NmpSW: 7.6(6) and Bootstrap 6.1(5). According to the article for upgrading the ROMMON, the last step is to 'Show Boot' to make sure everthing looks right. Here are three examples of what 'Show Boot' displayed. I'm particulary concerned about the 'Boot Variable' line. It varies on each switch. Example 1 is how I believe the boot variable should display after upgrading.? But, example 2 shows the new 7.6(6) .bin file as well as the one it replaced, 7.4(2). And example 3 shows the pomupgrade .bin file.

Not sure why these vary? Each switch seems to working fine, is there any thing to be concerned about with the way the Boot Variable line is displaying and can I just leave it the way it is, or do I need to do something to correct it? If so, can you give me some directions or a support article on how to correct it?


Example 1

mas5-4006> show boot

BOOT variable = bootflash:cat4000-k8.7-6-6.bin,1;bootflash:cat4000.6-3-5.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg


Configuration register is 0x2

ignore-config: disabled

auto-config: non-recurring

ROMMON console baud: 9600

boot: image specified by the boot system commands


Example 2

Console> show boot

BOOT variable = bootflash:cat4000-k8.7-6-6.bin,1;bootflash:cat4000-k8.7-4-2.bin,

1;bootflash:cat4000.6-3-5.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg


Configuration register is 0x2

ignore-config: disabled

auto-config: non-recurring

ROMMON console baud: 9600

boot: image specified by the boot system commands


Example 3

mas22-4006-1> show boot

BOOT variable = bootflash:cat4000-promupgrade.6-1.bin,1;bootflash:cat4000-k8.7-6

-6.bin,1;bootflash:cat4000.6-3-5.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg


Configuration register is 0x2

ignore-config: disabled

auto-config: non-recurring

ROMMON console baud: 9600

boot: image specified by the boot system commands


Thanks

The boot variable will use the first valid filename from the list.


The boot variable is populated by the boot system command in the switch running configuration.


You can modify the boot variable string by removing/adding information from the boot system command.

Get rid of the boot statement pointing to the prom upgrade on example 3 , "clear boot system flash bootflash:bootflash:cat4000-promupgrade.6-1.bin . The rest are fine . If you don't want the old files in bootflash just delete and squeeze bootflash and then clear the corresponding boot statement pointing to that old image.
