Solved: boot-start-marker and boot-end-marker

wuh · ‎03-26-2009

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?

thanks,

Han

Hello Han,

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

use

sh run | inc boot system

sh conf | inc boot system

So I think it shouldn't be a real issue

Hope to help

Giuseppe

Beginning with IOS Version 12.3(4)T, Cisco introduced the concept of boot markers. Essentially, all boot system command lines are now placed between two permanent boot markers located within the configuration file. These markers cannot be erased and make locating the boot system commands easy.
