Alcatel Unleashed

I have configured OS6450-24 as DHCP-server ,its working fine,'

But I need to release all lease provided by DHCP Server in my case OS6450.

is their any command on any way to do it.
I have tried :
dhcp-server disable
dhcp-server enable

reboot the switch many times, but nothing worked out,Please help!!!

not sure and never tested: there is a dhcp-lease-file within the switch-directory. disable dhcp-server, delete this file, change the lease-time to a shorter value, enable and restart the dhcp again.
