Take a "snapshot" of the configuration before major change

[Localhost]

Hi everyone!

I have recently started working with Extreme moving from HP/Cisco which we still use.

With Nexus I can checkpoint the configuration of the switch before a major change and possibly tell the switch that I lock myself out to apply the old configuration after a certain amount of time. This is a very important feature for us as often we work with devices very far away.

I have tried to look into the forum and documentation but I could not find a way to do this:

- take a snapshot/checkpoint of the config and tell the switch to apply the old config unless I do something (i.e. with Cisco before major change I schedule a restart in 10 minutes. I change the configuration, if that locks me out for some reason the device reboots with the old config

I am sure this is a common requirement and wondering if you had experience with this.

thanks heaps,

Nick

Hey Nick

There is a script that was written that allows for us to implement a roll back feature where the config will not take affect until you do a save. It is a simple thing to implement and when I find it I will post a link to it.

Another thing that customers have used in the past is to use a script to use the old config and set a reboot timer. The way it works if you are making a change remotely and you lock yourself out the script will load the old config and automatically reboot to get you back in business. I have seen this used mainly during code upgrades or major config changes during a cutover where the customer doesn't want to drive to a far distance.

Let me see if I can find that script and will post it tomorrow.

Hope that helps

I believe it works the same way on EXOS. Schedule the reset and do not save the config. If you cut yourself the reset is performed with the last saved config.
