Hi Cannot change dhcp ip starting and ending ip address. I want to change starting ip address and ending ip address. After changing it to make the range smaller, and click on Update & Save to Device successfully. however, when click on the new created dhcp server, I can the original starting and ending ip address are still there. Why it happen? Thanks

- Look at impact of your commands by taking diffs on the running-config (before after ->with the CLI) , then subsequent use of the CLI and changing running config 'manually' (not with GUI) , may be easier to achieve what you need ,

I've just tested on 17.9.3 and when I change it then Update and Apply it works correctly so the question is what version are you using? It might also be a browser issue.

You're a regular poster so you should know by now to quote the model and software version you're working with.

Personally I would just use CLI to configure DHCP - quicker and easier and simpler.

@Rich R you are right. and I agree with you. this should not be a problem. My version is 17.9.2. I also do not think it is software issue. The reason why i brought the question is to further confirm my thought and find if there is other issue. Thanks
