Hi all,
We are using ISE to deploy IP-SGT mappings to several switches and we just observed that after the deployment the switch config is not saved automatically (by ISE). Obviously if the config is not saved manually and a power outage occurs then the new mappings are lost.
Any feedback will be welcomed, we are interested to see if this is as designed or maybe a bug so we will open a TAC case.
Thanks,
Adrian

My guess is that it is by design. IP-SGT mappings change over time and ISE regularly communicates with the switches using SXP to ensure the mappings are there, updated, or removed as necessary. If the switch were to restart, it would re-establish the SXP connection with ISE and the mappings would be pushed down again.
Someone could be in the middle of making other changes on the switch and I don't necessarily think it would be good for ISE to save the configuration which would include other changes outside of IP-SGT mappings.

In my opinion when ISE is the pushing static IP-SGT mappings it acts like a kind of automation tool that the engineer is using in a controlled way as he needs to trigger the deployment manually using the deploy button so no unexpected saves can happen. It doesn't make a lot of sense to connect to each and every affected device separately and save the config manually when the automation is used, if not doing it automatically then at least letting the user decide if the save should be done.
