running-config to candid-config OR candid-config to running-config

L0 Member

Hello All,

 

Kindly help understand the concept.

 

I am preparing for my PCNSE and I was reading through the a manual provided by Palo Alto (EDU-255).

 

Under Configuration Operations, at one point the document reads that “the running configuration is copied to a candidate configuration during firewall startup”. On the very next page, the document reads that “at boot time the latest configuration on disk is loaded to the candidate configuration in control-plane memory. An auto-commit copies the candidate configuration to the running configuration in control-plane memory. The running-configuration in control-plane memory is then pushed to the data-plane memory”.

 

 

Thanks,

learner

the first description is the same as the second, only with fewer steps 🙂

 

upon reboot the candidate configuration is purged. once the device is booted, the stored config (running-config.xml) is loaded as candidate-config.xml and then pushed onto the chipset

 

the running and candidate are 2 files, while the 'live' config is the machine translated snippets that are loaded onto the chips/in memory to do their job

the running-config.xml is the master file

 

hope this makes sense

When  you say that upon reboot candidate config is purged does it mean that it gets purged with runnin config ?

 

live config is always the running config?

it is removed from 'working' memory (on the management plane) and overwritten with the running-config upon reboot

 

running-config is the config that has been pushed upon the dataplane processes so running-config is always the configuration that is being enforced by the firewall, while the candidate config is the 'admins playground' for as long as the admin does not commit

Thank you!

 

You cleared the doubt.
