主題: Re: Remove Lease via omshell
Hi Billy
Selecting by anything only works when it matches one lease. That hardware-address must correspond to more than one lease, so in that case hardware-address and dhcp-identifier are not unique selectors. ip-address is always a unique selector for a lease.
I don't know about removing a lease, I thought that was only for host entries, perhaps someone else can help?
