IOS mismatch in boot and show ver

[mohib.abdul@cox.com]

Hi,

I have a   WS-C3750V2-48PS-S But here is the problem i am facing, when i do a show version on the device is see a different IOS than what i see in boot.

USER_SW1#show ver | in image|SW|Boot
ROM: Bootstrap program is C3750 boot loader
BOOTLDR: C3750 Boot Loader (C3750-HBOOT-M) Version 12.2(50r)SE, RELEASE SOFTWARE (fc1)
System image file is "flash:/c3750-ipservicesk9-mz.122-55.SE.bin"
Switch Ports Model SW Version SW Image
USER_SW1#show boot
BOOT path-list : flash:/c3750-ipservicesk9-mz.150-2.SE11.bin
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : no
Manual Boot : no
HELPER path-list :
Auto upgrade : yes
Auto upgrade path :
NVRAM/Config file
buffer size: 524288
Timeout for Config
Download: 0 seconds
Config Download
via DHCP: disabled (next boot: disabled)

Also i do not see anything for the boot in show run or show start

USER_SW1#sh run | in boot
boot-start-marker
boot-end-marker

I am confused as to what is  going on. can anyone shed some light on this. 

Regards,

Mohib

Un-huh. What's in flash and what does show bootvar reveal?

You can't find any important info about boot process in running-config. However, you can use following to find a lot of details about boot image, etc:

show version (current version of IOS, bootloader version, type of equipment, uptime, location of IOS image and so on)

show boot (version of image that used now and will be used on next reboot, location of config files)

dir or show flash: (content on flash, where you can check some necessary files, e.g. IOS file, located on flash by default in most types of devices)

This is the Bootloader, 12.2(50r)SE.

This is the IOS version the switch is running, 12.2(55)SE.

Bootloader and IOS version are two different "OS".  The only way to upgraded the bootloader is to upgrade the IOS.  If, say, the IOS was upgraded to 15.X, then the bootloaded will get automatically upgraded.
