address. If no reply is received, the DHCP server can assign the IP address.

grayed out and cannot be edited.
● Interface
Specify the interface via which the IP addresses are dynamically assigned.
● Subnet
Enter the network address range that will be assigned to the devices. Use the CIDR
notation.
● Lower IP Address
Enter the IP address that specifies the start of the dynamic address band. The IP address
must be within the network address range you configured for "Subnet".
● Upper IP Address
Enter the IP address that specifies the end of the dynamic address band. The IP address
must be within the network address range you configured for "Subnet".
● Lease Time
Specify how long the assigned IP address remains valid. Once this period has elapsed,
the device must either request a new IP address or extend the lease time of the existing
IP address.
