Examples of using the <CONFIG> tag

[Jamie Getty]

Hey there. I'm looking to gain an understanding on the <CONFIG> tag ,and by extension, some understanding on konfd.

I want to generate a running configuration of my device, by logging each command that the user enters. Hopefully, we can then use this config to set the device to an earlier state.

I thought it would be as simple as adding the tag "<CONFIG operation="set"/> in the relevant .xml file, but that doesn't seem to be enough to log the command. I know there's a daemon called konfd that records commands, but I'm not sure how to utilize that.

What steps do I need to start logging user commands?

Currently, I am using a command called "capture start" to begin logging commands. This command uses a config tag to start konfd as such:

 <COMMAND name="capture start"
                     help="Start CLI commands capturing">
   <ACTION>rm -f ${capfile}; /sbin/konfd; cfg_stopped=0; sleep 1</ACTION>
   <CONFIG operation="unset" pattern="^configure" file="${capfile}"/>
 </COMMAND>

However, from now on, I want to log all commands, starting from boot.

I thought about calling konfd from the startup XML file, but since the <STARTUP> tag doesn't let you nest <CONFIG> tags inside it, I don't know how to properly configure konfd from here.

There is a special hook type for logging.

<HOOK name="log" builtin="hook_log@my_plugin"/>

You can write your own klish plugin, define a hook for logging with function type

CLISH_HOOK_LOG.

The "config" hook is for something like cisco's running-config, not for logging.

Thank you for the advice. Still, I think it would do good for me to get a better understanding of how konfd and konf work.

If I did want to do a cisco-style running config for all commands, what is the best way to start konfd, and the best way to log to the running config?

[Serj Kalichev]

To implement cisco-like running-config you need to execute konfd daemon. The klish (clish binary) can interact with it using CONFIG options. The konf utility is just a simple utility to interact with konfd daemon using shell (testing for example).
