Hello everyone,
I would like to verify what is the actual boot image running on my catalyst 6503 E SUP 2T.
My IOS is s2t54-adventerprisek9-mz.spa.151-2.sy.bin and my Rommon is ok with the version 12.2(50r)sys3.
I tried many command without any success. Here's the commands that i have been tried:
- show bootvar
-show version
- show module
- show run
- show boot
I try to see the boot image that is use by my 6503 E and not only one that is configure under boot command.
I have configure my 6503 e like this: boot bootstrap bootdisk:/s2t54-boot-mz.SPA.151-2.SY.bin.
Thanks!

We're only starting to deploy sup2Ts, but its show version doesn't have something like (from a sup720):
System image file is "sup-bootdisk:s72033-advipservicesk9_wan-mz.122-33.SXI9.bin"?
[edit]
Did find one of our new sup2Ts, and its show version has:
System image file is "bootdisk:s2t54-advipservicesk9-mz.SPA.150-1.SY3.bin"

I am looking for the boot image and not the system IOS image . The boot image is a smaller version of the system IOS image that can be use for TFTP or access the switch if the IOS is corrupt.
Her's my two file under my flash:
1. IOS Image : s2t54-adventerpriseK9-mz.spa.151-2.SY.bin
2. Boot image: s2t54-boot-mz.spa.151-2.SY.bin
These are the images on my flash but again, I want to check the active, running image on my switch.
I understand that I can see the active running IOS image with different command. Like with the show version and show module (FW) but what about the active running Boot image.
Is it possible to see it ?
I need to verify that the one configure is really the one that is active and running
Thanks!

Ah, well if the sup2T is like the 720s, the actual booting is done by the images on the SP and/or RP. They, in turn, boot the IOS (according to boot strings, if so configured and enabled).
For multiple IOS images, including a reduced IOS image, you would need to look at the boot strings. Then check, for any image not actively running, check whether there's really an image where the boot string says it should be.
Again, not very familiar with the sup2T, but on a 720 you can specify just a device as part of the boot string, and the boot process will look for any valid image (I believe restricted to the root of the device) and boot it.
In other words, except for the running image, you need to analyze how the device is configured to boot using the boot strings (i.e. config-reg), whether boot strings have been defined, and whether there are valid images on your different flashes, and whether they all agree.
Even without explicit boot strings, a (720) can be configured to default boot using first valid IOS image found on its default boot device.
You asked about the "running image", again show version tells you that, but for how that image was actually selected during the boot process depends on all the above. Again, what image might be selected to boot into, depends on all the above.
As some of the boot devices can be changed on the fly, an accurate analysis of what should boot isn't a guarantee of what will be actually be booted at time of boot.
Personally, I like (on 720s):
boot system disk1:
boot system disk0:
boot system bootdisk:
Which allows me to change IOS by changing CFs in disk1 and disk0, and without touching config.
However, others prefer explicit device:IOSFileName.

Thanks for your answer !
So, no command exist to verify what is the version of this image tha running on my router: s2t54-boot-mz.spaxyzSY.bin
I can only verify the image save under the flash with the command (dir) and I can verify what is configure under the boot string. no other command exist to verify if what is configure is really the same image that is running. When i say image, I always refer to the same image s2t54-boot-mz........... not the system image.
Thanks again!

The last is the boot image as also shown in show version results.
The show version also shows actual running image and where it was loaded from.
So, unclear why you believe this infomation is not available.

THanks again for your help !
I was confused because I heard that the Rommon image, the image you refered to( V12.2(50r)SYS3)
is not the same as the Boot image that I refered before (s2t54-boot-mz-spa...).

I believe that IOS "boot" version is unnecessary. The ROMMON can boot the main IOS directly.
