HereIGoAgain2601 Posted July 27, 2023 Posted July 27, 2023 Does anyone know if there is a command that can bulk apply an IP helper to all of the VLANs? We have an old LA Cisco network that has been split out into hundreds of VLANs and need to change the IP on our DHCP server! I've got one that works 1 at a time - just looking for a shortcut! Surely there must be one! Cheers!

HereIGoAgain2601 Posted July 27, 2023 Author Posted July 27, 2023 Amazing, that's just saved me hours of work. Thanks so much!
FN-GM Posted July 27, 2023 Posted July 27, 2023 (edited) You're welcome! Another tip, but it will cause an outage. 1. Download the config 2. In a text editor find and replace 3. Load the new config as a startup config 4. Reload the switch Edited July 27, 2023 by FN-GM 1
