Does this functionality exist in Cisco IOS?

Question

Cisco

Good afternoon!
Previously, I often worked with Junos, at the moment I have to deal with IOS more and more.
Two possibilities are really missing:
- see the changes made to the configuration (on Junos this was possible with the show system rollback A compare B command)
- ask the piece of hardware to drop the configuration after some time has elapsed (ala commit with the specified amount of time
) not given. In my opinion, I have seen equal functionality before, but I can’t find it.
Prompt, please, whether there is something similar at a tsiska?

Answer 1

view the changes made to the configuration (on Junos this was possible with the show system rollback A compare B command)

show archive config differences running-config startup-config

You will first need to activate configuration archiving ( archive).

Answer 2

Watching what IOS. The usual one is not, XR can, XE is also kind of. The reason is, XR-XE are built on BSD (like Junos itself), and the usual one is of its own design.
However, in IOS there is no need to commit-apply anything. You just drive in the lines, if something does not start, you reboot the piece of iron. You can specify a reboot after a certain time (for example, after 5 minutes).

Answer 3

- set the hardware to drop the configuration after some time has elapsed (ala commit with the specified amount of time)
reload in 5
... configure ...
if lost - reboot, the config was restored
if not lost and everything is OK:
reload cancel

Answer 4

Certainly. IOS XR can definitely commit and rollback
