I configured static IP addresses but their previous addresses are still there in the dashboard. Thanks! Hi @jvelasco, A 'button' to clear DHCP Leases from dashboard is certainly a feature request at this time point in time as others have commented. However, there is a way to clear the DHCP Leases on a VLAN without having to reboot the appliance by following these steps: - Create a DHCP Reservation on the VLAN that blocks out the entire DHCP range - Save the configuration and let MX downloads it (might take a minute or two) - Clear the DHCP Reservation and save the configuration again Hope this helps, if you are still having trouble, I would recommend reach out to support (that's whom I got this info from). You can find support information from dashboard under Help > Get Help. Cheers, -Alex UPDATE FOR ANYONE THAT MIGHT RUN INTO THIS I found this thread because I had to do this for a VOIP rollout. I repeated these steps - Decreased the DHCP Lease Time to 30 minutes Create a DHCP Reservation on the VLAN that blocks out the entire DHCP range Save the configuration and let MX downloads it (might take a minute or two) Clear the DHCP Reservation that blocks out the entire DHCP range Save the configuration again It seemed to work at first. All client DHCP leases were removed from the dash... except they some came back with the original entries. All of the phones are still advertising that their lease time will expire in 20+ hours. Effectively maintaining the lease time they originally had. Not sure if this is because they're VOIP endpoints, but it only half worked. The machines on the same VLAN cleared out their DHCP leases and were on the new 30 minute lease time, the phones were not.
