Hi Team,

Whenever i upgrade an IOS i run this command to verify the file after
the download to check the health of the file. This time for upgrading
from 12.2(40) SG to 12.2(50) SG2 I downloaded the new IOS into the
bootlfash and i am getting this wierd warning when i run the verify
command and am not sure what to do with it. If you have any idea what
it means pls let me know. I have the upgrade scheduled in a day so
request your prompt response. The better side of the whole thing is
that i am getting the same warning for the existing IOS (cat4500-
ipbasek9-mz.122-40.SG.bin) as well. The switch is up since 10 weeks
with this IOS.
