We have two new 6503E/12.2(17d) installed. I found there is no boot-start-marker and boot-end-marker seen in the config.
When I put the boot command, I didnt see these two only boot command itself in the config.
Does it affect anything?
do you see the boot system commands ?
compare also with sh bootvar
boot-start-marker and boot-end-marker are simply there to help us locate boot commands: for several years they weren't present but boot system commands could be used in the same way
sh run | inc boot system
sh conf | inc boot system
So I think it shouldn't be a real issue
Hope to help
