Digi 90000566_H manual Using the web UI, Disable all reservations that were previously added

	set dhcpserver
Examples	Configure the IP address range for the DHCP server scope and enable it
	set dhcpserver item=scope action=set enabled=on
	startip=10.30.1.150 endip=10.30.1.199
	Since the “leasetime” and “offerdelay” options are not specified, the default
	values for them are used, unless they were previously changed to another
	value by use of a “set dhcpserver item=scope” command (or using the web
	UI).
	Add an IP address reservation for a client:
	set dhcpserver item=reservation action=set range=1 enabled=on ip=10.30.1.195
	clientid=00:09:26:19:51:05
	Since the leasetime option is not specified, the DHCP server's scope lease
	time is used, unless a lease time was previously changed to a value by use
	of a “set dhcpserver item=reservation action=set range=1” command (or
	using the web UI).
	Disable all reservations that were previously added:
	set dhcpserver item=reservation action=set range=all enabled=off
	Permanently remove a reservation that was previously added:
	set dhcpserver item=reservation action=revert range=1
	Any client that has the lease for the reserved IP address that is removed in
	this manner, will still keep its lease. However, without the reservation,
	future address leases to that client are not guaranteed to be for this same
	IP address, which is the purpose of a reservation.
	Add an IP address exclusion range for the scope:
	set dhcpserver item=exclusion action=set range=1 enabled=on
	startip=10.30.1.170 endip=10.30.1.179
	This exclusion instructs the DHCP server to not issue leases for the IP
	addresses from 10.30.1.170 to 10.30.1.179 inclusive. Note that reservation
	leases may be configured for any address in that range, and the DHCP
	server will permit a lease of such an address to the correct client only. That
	is, reservations override exclusions.
