Clear DHCP leases - MX84

Hi, 

May I know if there is a way to clear out the DHCP Leases in a certain VLAN?

I configured static IP addresses but their previous addresses are still there in the dashboard. 


Thanks!

Re: Clear DHCP leases - MX84

I don't know the answer.  You could try turning DHCP off and then back on again.

I believe as soon as the client disconnects and reconnects to the network it will go through the DHCP process again. At that point they will receive the newly assigned static address. If they try to renew the lease I think the DHCP server will refuse and assign them the static IP address too.

Every time I'm in a situation where I need to clear a DHCP lease on Meraki, I hit this button so hard...

There is no way (that I know of) to clear a DHCP lease manually in Meraki. Best is to lower lease time, in the DHCP server, and wait for the leases to renew, to the shorter lease time.

Hi,

I think that is the "wish button"?

Well, I will check your suggestion. Hopefully later on the update, they will have that feature.

Set the DHCP lease Time to 30 minutes in the evening when everyone leaves and wait.. That's how I handle this.

Re: Clear DHCP leases - MX84

Hi,

I've done two options, setting it at 30 minutes and then reboot.  At last, it renews all leases. 

But I think the Cisco Meraki must do something about this because it is really important. 


Thanks.

Re: Clear DHCP leases - MX84

is there any development going on for this issue? Manually changing dhcp leases to 30 min at the eod is not the ultimate solution. I hope there would be a select and delete option somewhere for removing dhcp leases.
