Hi @ktbyers - I recall we have discussed about this in the past and - if I'm not wrong - you said you have an idea how to implement this. Is that correct? If so, could you please expose a bit the idea, I'd like to give it a try. Thanks!

@mirceaulinic It looks like we should be able to do something like this (note, time is in minutes).

test123#configure replace flash:/candidate_config.txt force time 2
Rollback Confirmed Change: Backing up current running config to flash:pynet-rtr1-cfgMar--8-09-32-38.872-PST-19

@mirceaulinic I also see this configuration lock which we probably should be using:

pynet-rtr1#configure terminal lock 
Configuration session is locked. The lock will be cleared once you exit out of configuration mode.
Enter configuration commands, one per line.  End with CNTL/Z.

In another SSH session, I then tried:

pynet-rtr1#conf t
Configuration mode is locked by process '78' user 'pyclass' from terminal '8'. Please try later.

Ah that's really nice! I believed that's going to be way harder.
I plan for next week to focus more on the whole epic: napalm-automation/napalm-base#214 and I will try an implementation if you don't beat me :)

@mirceaulinic Yes, Cisco IOS for all its automation failings has so many features in it...that you can retrofit a lot of things onto it.

We have PR on this. Closing the issue.
