CAT9K_IOSXE Guestshell ZTP - works only for python not shell script ?

gnijs · ‎06-26-2018

Hello,

Can someone confirm that on a Cat9000 ZTP is only triggered when the DHCP bootfile option returns a .py file ??

So i have made a nice shell script to do ZTP, but the guestshell is not triggered when i point the bootfile to a .sh file ??

Loading http://1.1.1.1/ztp/ztp.sh
Loading http://1.1.1.1/ztp/ztp.sh

(-> he loads the file, path detected via dhcp boot option)

(-> when it is a .py file, it triggers guestshell here, but when it is a .sh file, it doesn't ??)

ZTP requires Python scripts. You can have a Python script invoke your .sh after copying it down (or encode it in the script and write it to disk once running in guestshell), but I think it would be better to port your logic from Bash to Python.

**bleep**. I think i am just going to spawn a new bash shell from within python. Problem with python is that from within python it is difficult to install new modules and how about adding environment variables for proxy or DNS access....in bash, you just source some downloaded .sh scripts.

With the dohost command, you could likely do what you need from Bash to bootstrap. In terms of additional Python libraries, you could still download stuff and then "import" it.
