I have a Cisco 4948e (the silver one not the gross teal one)
I am booting into rommon after copy run start. Config-register is 0x2102
This is after the initial setup as I have rebooted the switch with no config just fine.
rommon 5 >dir bootflash:
File Size (Bytes) File Name
---------------------------------------
40128461 cat4500e-ipbasek9-mz.152-4.E5.bin
39979805 cat4500e-ipbasek9-mz.152-4.E7.bin Total space = 128206848 bytes, Available = 38068224
bytesrommon 6 > [interrupt]rommon 6 >boot flash:cat4500e-ipbasek9-mz.152-4.E7.bin
Invalid filename flash:cat4500e-ipbasek9-mz.152-4.E7.bin. It must begin with device name
It says its an invalid file name, but boots right up to my previous config.
I don't think my other switches have this problem.
Thank you, Thank you!

#dir bootflash: <--- check the this file available in bootflash - cat4500e-ipbasek9-mz.152-4.E7.bin
if the image not in bootflash, copy from USB or what ever source.
#configure terminal
(config)#boot system flash bootflash:cat4500e-ipbasek9-mz.152-4.E7.bin
(config)#end
#write memory
Check the boot variable again to make sure it is set properly so that the switch boots up the correct system file on the next reboot.
#show bootvar
Configuration register is 0x2102
Reload the device test it booting correctly.

try below
>boot bootflash:cat4500e-ipbasek9-mz.152-4.E7.bin
Once it boots check the boot variable. and setup accordingly.
#show bootvar

I get the following from show bootvar
komodo#show bootvar
BOOT variable =
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

- Take care of this good suggestion :
>boot bootflash:cat4500e-ipbasek9-mz.152-4.E7.bin

I have done some more research and it looks to be a common issue on the 4500 series of switches.
Have any sources of how to configure the bootvar correctly?
THANK YOU!

Hello
Check to see what currently resides in you flash directory
dir /all file systems
If the old and image files are their verify their integrity
verify /md5 flash:/xxxx.bin
Next remove old bootvar and create a new one
config t
no bootvar or no boot
boot system flash:/new-image.bin
boot system flash:/old-image.bin
end
write
show bootvar or boot
reload
02-07-2021 04:37 AM
komodo#verify /md5 bootflash:/cat4500e-ipbasek9-mz.152-4.E5.bin
.........................................................................................................................................................................................................................................................................................................................................................................................................................................Done!
verify /md5 (bootflash:/cat4500e-ipbasek9-mz.152-4.E5.bin) = b8724ee095836a5f012ce21967061e7e
komodo#
komodo#verify /md5 bootflash:/cat4500e-ipbasek9-mz.152-4.E7.bin
...........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................Done!
verify /md5 (bootflash:/cat4500e-ipbasek9-mz.152-4.E7.bin) = 88f5966e3d1f4181b31bb7d40a7f53e2
config t
no bootvar or no boot
boot system flash:/new-image.bin
boot system flash:/old-image.bin
end
write
show bootvar or boot
reload
I will try this shortly
THANK YOU!

Hello
has now you have confirmed its bootflash make sure that is specified.
boot system bootflash:/new-image.bin
boot system bootflash:/old-image.bin
02-07-2021 07:48 AM
This ended up working
#configure terminal
(config)#boot system flash bootflash:cat4500e-ipbasek9-mz.152-4.E7.bin
(config)#end
#write memory
Check the boot variable again to make sure it is set properly so that the switch boots up the correct system file on the next reboot.
#show bootvar
Configuration register is 0x2102
