DHCP Static Binding on Cisco IOS

We are replacing our Core L3 switch, but we would like to keep the DHCP bindings, so it will be less of a disruption.  Is it possible to export the current bindings from the old switch and import them into the new?

Re: DHCP Static Binding on Cisco IOS

Hi

You can use the command ip dhcp database command to store all binding on a tftp or ftp drive.

Then if you configure the dhcpn pool on both switches, you'll avoid ip conflict.

Here a documentation you can read:

Thanks
